the growing use of geosynthetics in sustainable construction

 Geosynthetics are a vital component of modern sustainable construction, enabling engineers and architects to design more eco-friendly, cost-effective, and resilient infrastructure projects. By incorporating geogrid products into their plans, construction professionals can enhance soil stabilization, erosion control, and drainage systems while reducing the environmental impact of their work.

One of the primary benefits of using geosynthetics in sustainable construction is their ability to improve soil stability and prevent erosion. Unstable soils can cause significant damage to infrastructure, leading to costly repairs and maintenance issues. Geogrids provide a reinforcing layer that improves the soil's load-bearing capacity and resists the forces that can cause instability, such as wind, water, and seismic activity. As a result, structures built with geogrids are more durable and require less maintenance over time.

Another key advantage of geogrids is their ability to facilitate proper drainage, which is crucial for sustainable construction. By enabling water to flow freely through the soil, geogrids can help prevent flooding, reduce runoff and soil erosion, and minimize the potential for soil contamination. This, in turn, can help protect local ecosystems and groundwater resources.

In addition to their practical benefits, geosynthetics also offer several sustainability advantages. For example, many geogrid products are made from recycled materials, reducing waste and promoting circular economy principles. Furthermore, by enhancing the durability and longevity of infrastructure projects, geogrids can help reduce the carbon footprint associated with frequent repairs and replacements.

Geogrids are used in a wide range of sustainable construction projects, including roadways, bridges, retaining walls, and green roofs. They can also be employed in landscaping, agriculture, and military applications, further highlighting their versatility and potential. As the demand for sustainable infrastructure continues to grow, geosynthetics will undoubtedly play an increasingly critical role in shaping the future of construction.

In conclusion, geogrids are a valuable and essential tool for sustainable construction. By improving soil stability, facilitating proper drainage, and offering numerous sustainability benefits, geosynthetics are helping to create more resilient, eco-friendly, and cost-effective infrastructure projects. As the world continues to prioritize environmental responsibility, geogrids will play an increasingly vital role in meeting these goals.

The Mount Tai - leader of the five sacred mountains

Mount Tai, located just north of Tai’an city in East China’s Shangdong province, is a mountain of historical and cultural significance. The word tai in Chinese means stability and peace and the name Tai'an is attributed to the saying: "If Mount Tai is stable, so is the entire country" (both characters of Tai'an have an independent meaning of stability and peace). Mount Tai is crowned by Jade Emperor Peak (in Chinese mythology, the Jade Emperor is the most powerful god in heaven) with an altitude of 1,545 meters.
The formation of Mount Tai dates back to the Archeozoic Era, and now it is growing at the speed of 0.5 millimeters per year. It faces the Yellow Sea to the east and the Yellow River to the west, and is in the neighborhood of Confucius’ hometown, Qufu, and the City of Springs, Jinan. In 1987, Mount Tai was listed as both World Natural Heritage and World Cultural Heritage by UNESCO.
Leader of the Five Sacred Mountains
mount taiMount Tai, leader of the five sacred mountains
Among the Five Sacred Mountains of Taoism (the other four are Heng Mountain of Hunan Province, Hua Mountain of Shaanxi Province, Song Mountain of Henan Province and Heng Mountain of Shanxi Province), Mount Tai is only the third highest. Why it is seen as the leader of the Five Sacred Mountains? In absolute terms Mount Tai can not be considered as the highest of China’s mountains, but because it is close to the sea and rivers and rises abruptly from the relatively low rolling hills and Qilu plains, its relative height is quite impressive, with an altitude difference of 1395 meters within nine kilometers. Moreover, in Chinese culture, east is regarded as a sacred direction, since it is where the sun and the moon rise. Therefore Mount Tai is often regarded as the first of the Five Sacred Mountains. It is associated with sunrise,
birth and renewal.
For thousands of years, Mount Tai has been the sacred mountain where Emperors held the ceremony of offering sacrifices to heaven and earth to pray and say thanks for peace and prosperity. Seventy-two emperors are said to have performed mountain worship ceremonies on Mount Tai. Among them, Emperor Wu of the Han Dynasty had visited Mount Tai eight times. It is the first and foremost thing for emperors to do when they ascend to the throne, because Mount Tai is seen as the symbol of the county’s peace and prosperity.
Mount Tai held a sacred position in state politics, and also enjoyed a high status in the world of Taoism and Buddhism. The temples on its slopes have been a destination for pilgrims for 3,000 years. View famous mountains in China.
Natural Beauty
Featuring antiquity, grace, serenity of seclusion, risk and wonder, Mount Tai boasts 156 peaks, among which Jade Emperor Peak, Heaven Candle Peak and Sun Viewing Peak are the most famous; 138 cliffs, the highlight of which is Fan Cliff; 72 caves; 72 grotesque stones, among which the Immortal Bridge is the most distinctive; 130 streams; 64 waterfalls, including the renowned Dragon Pool Waterfall, Yunqiao Waterfall and Santan Waterfall; and 72 springs. It lies in the zone of oriental deciduous forest, with about 80 percent of its area is covered with vegetation. The flora is known to comprise almost 1,000 species. Some of the trees in the area are very old and have cultural significance, such as the Han Dynasty Cypresses, which were planted by Emperor Wu of the Han Dynasty, Tang Chinese Scholar Tree (about 2,100 years old), Welcoming Guest Pine (500 years old) and Fifth Rank Pine, which was named originally by Emperor Qin Shihuang, but was replanted about 250 years ago.
Its distinctive natural environment gives Mount Tai four natural wonders: Sunrise on Mount Tai, Rime and Glaze Scenery, "Buddha’s Light" on Mount Tai and the Sea of Clouds.
Cultural and Historic Relics
The majesty of Mount Tai has profoundly moved many visitors at all periods of history: the emperors who claimed they were the sons of heaven, the proud high-ranking officials, brilliant poets, Buddhists, Taoists and ordinary people too. They left numerous cultural and historic relics. There are in total 2000 historical relics. There are 58 ancient building complexes, which are mainly in Ming and Qing Dynasty style, and 29 are well-preserved. They built at the foot of Mount Tai and along its slopes; among which Dai Temple, Bixia Temple, Hong Mountain Gate, Nantian Gate and Daizhong Arch Gate are masterpieces among ancient Chinese buildings and the representation of China’s culture of thousands of years. Interestingly, from Dai Temple, (the place for offering sacrifice to the Emperor of Earth) located at the foot of Mount Tai, to Jade Emperor Summit, the temples built along the slopes are said to compose a ten-kilometer road from the nether world to heaven.
Besides, there are countless inscriptions on the cliffs and steles from historic celebrities, using such laudatory descriptions of Mount Tai as “towering majesty in the east”, “supporting the sky and holding up the sun” and “as lofty as heaven”.

The Forbidden City — 9999 Rooms for 14 Emperors

The Forbidden City is:
the best-preserved imperial palace in China,
the largest ancient palatial structure in the world, and
the essence and culmination of traditional Chinese architectural accomplishment.
History
The Forbidden City, situated in the heart of Beijing, was home to 24 emperors of the Ming (1368–1644) and Qing (1644–1911) Dynasties.
The construction of the grand palace started in the fourth year of Emperor Yongle of the Ming Dynasty (1406), and ended in 1420.
In ancient times, the emperor was said to be a son of Heaven, and therefore Heaven’s supreme power was bestowed upon him. The emperors’ residence on earth was built as a replica of the Purple Palace where God was thought to live in Heaven.
Names: Such a divine place was certainly forbidden to ordinary people and that is why the Forbidden City is so named. Originally called Zijin Cheng ('Purple Forbidden City'), in China now it is usually called Gugong (故宫 /goo-gong), the 'Former/Old Palace'.
Features
It is the world's biggest ancient palace.
It is considered to be among the world's top 5 most important palaces.
China's most popular single site tourist attraction.
The structure is almost 600 years old.
Home of dynastic clans for 500 years.
A million articles are considered national heritage.
1987 UNESCO World Heritage List
The largest collection of ancient wooden structures in the world.
A stunning array of ancient treasures and buildings: with ancient porcelain and jade, gardens, plazas, historic sites, and 9,999 rooms
Entrance
Most travelers enter the Forbidden City through Tian'anmen, the Gate of Heavenly Peace. Through the gate, across an expansive brick-paved square, you will reach the main entrance to the palace, Meridian Gate (Wumen in Chinese).
Meridian Gate was the place where the Emperor announced the new lunar calendar on the winter solstice. Enter through Meridian Gate, and go across Golden Stream Bridge, then you will arrive at the outer court. The Forbidden City falls into two parts: the outer court and the inner palaces.

Terracotta Army - Xi'an China

The Terracotta Army (Chinese: 兵马俑; literally: "Soldier-and-horse funerary statues") is a collection of terracotta sculptures depicting the armies of Qin Shi Huang, the first Emperor of China. It is a form of funerary art buried with the emperor in 210–209 BCE and whose purpose was to protect the emperor in his afterlife.
The figures, dating from approximately the late third century BCE, were discovered in 1974 by local farmers in Lintong District, Xi'an, Shaanxi province. The figures vary in height according to their roles, with the tallest being the generals. The figures include warriors, chariots and horses. Estimates from 2007 were that the three pits containing the Terracotta Army held more than 8,000 soldiers, 130 chariots with 520 horses and 150 cavalry horses, the majority of which remained buried in the pits nearby Qin Shi Huang's mausoleum. Other terracotta non-military figures were found in other pits, including officials, acrobats, strongmen and musicians.
Discovery
The Terracotta Army was discovered on 29 March 1974 to the east of Xi'an in Shaanxi province by farmers digging a water well approximately 1.6 kilometres (0.99 mi) east of the Qin Emperor's tomb mound at Mount Li (Lishan), a region riddled with underground springs and watercourses. For centuries, occasional reports mentioned pieces of terracotta figures and fragments of the Qin necropolis – roofing tiles, bricks and chunks of masonry. This discovery prompted Chinese archaeologists to investigate, revealing the largest pottery figurine group ever found in China.
History
The mound where the tomb is located
The construction of the tomb was described by historian Sima Qian (145–90 BCE) in his most noted work Shiji, written a century after the mausoleum's completion. Work on the mausoleum began in 246 BCE soon after Emperor Qin (then aged 13) ascended the throne, and the project eventually involved 700,000 workers. Geographer Li Daoyuan, writing six centuries after the First Emperor's death, recorded in Shui Jing Zhu that Mount Li was a favoured location due to its auspicious geology, "famed for its jade mines, its northern side was rich in gold, and its southern side rich in beautiful jade; the First Emperor, covetous of its fine reputation, therefore chose to be buried there". Sima Qian wrote that the First Emperor was buried with palaces, towers, officials, valuable artifacts and wondrous objects. According to this account, 100 flowing rivers were simulated using mercury, and above them the ceiling was decorated with heavenly bodies below which were the features of the land. Some translations of this passage refer to "models" or "imitations;" however, those words were not used in the original text, which makes no mention of the terracotta army.
High levels of mercury were found in the soil of the tomb mound, giving credence to Sima Qian's account.
Later historical accounts suggested that the tomb had been looted by Xiang Yu, a contender for the throne after the death of the first emperor. However, there are indications that the tomb may not have been plundered.
Scientific research
In 2007, scientists at Stanford University and the Advanced Light Source facility in Berkeley, California reported that powder diffraction experiments combined with energy-dispersive X-ray spectroscopy and micro-X-ray fluorescence analysis showed that the process of producing Terracotta figures colored with Chinese purple dye consisting of barium copper silicate was derived from the knowledge gained by Taoist alchemists in their attempts to synthesize jade ornaments.
Since 2006, an international team of researchers at the UCL Institute of Archaeology have been using analytical chemistry techniques to uncover more details about the production techniques employed in the creation of the Terracotta Army. Using X-ray fluorescence spectrometry of 40,000 bronze arrowheads bundled in groups of 100, the researchers reported that the arrowheads within a single bundle formed a relatively tight cluster that was different from other bundles. In addition, the presence or absence of metal impurities was consistent within bundles. Based on the arrows’ chemical compositions, the researchers concluded that a cellular manufacturing system similar to the one used in a modern Toyota factory, as opposed to a continuous assembly line in the early days of automobile industry, was employed.
Grinding and polishing marks visible under a scanning electron microscope provide evidence for the earliest industrial use of lathes for polishing.
