A few days ago, Dadongshan Construction Sandstone and Basalt Mine in Yiyang County was successfully sold, the mining right is located in the territory of Yiyang County Lacquer Town, the mining minerals are sandstone and basalt for construction, the 11374 of sandstone mine for construction is 0.04 million tons, the basalt mine for construction is 14.8431 million tons, and the transfer period is 31 years. Finally, it was won by Shangrao Yitou Mining Co., Ltd., a local state-owned enterprise, for 157 million yuan.
2. Annual output of 4.7 million tons! A
few days ago, the Shangsi Ecological Environment Bureau of Fangchenggang City of Guangxi announced the EIA of Deli Mining's aggregate project with an annual output of 4.7 million tons. The project is located in Nongyan Mountain, Baiding Village, Fozi Village, Miao Town, Shangsi County, Fangchenggang City, Guangxi, with three crushing system production lines. The project relies on the limestone mine of Deli Mining, which can process 4.7 million tons of building aggregate annually after completion.
3. Annual output of 2 million tons of fine aggregate! China Resources Cement Pingyuan County Green Calcium-based Industrial Park (Phase I) Maoping Mine Project formally signed!
On April 20, the Pingyuan County Government of Meizhou City, Guangdong Province and Huarun Calcium Industry New Materials (Pingyuan) Co., Ltd. formally signed a contract on the Maoping Mine Project of Pingyuan County Green Calcium Industrial Park (Phase I).

4. Comments on
the dynamics of the concrete industry this week 1. The world's largest span arch bridge with a span of 600 meters was successfully closed
on April 30. Tian'e Longtan Bridge, the world's largest span arch bridge invested by Guangxi Communications Investment Group and constructed by Guangxi Road and Bridge Engineering Group Co., Ltd., was successfully closed with concrete roof ring. The rigid skeleton of the bridge is wrapped with C60 concrete, with a total volume of 27994 cubic meters and a weight of 72784 tons. It is divided into three construction links, namely, the bottom plate ring, the web plate ring and the top plate ring. It takes 221 days to balance the loading with the technology of 3 rings, 6 sections and 8 working faces. In view of the construction of concrete wrapped with stiff skeleton, the project developed the construction technology of "3 rings, 6 sections and 8 working faces", which solved the problems of large deviation of linear change caused by unbalanced loading of arch ribs and excessive tensile stress of concrete, and reduced the risk of cracking; Based on the principle of aerial work on the ground and combined with the design of suspended combined scaffolding, the problem of aerial work construction platform is solved.
2. The first concrete modular high-rise building in China will be completed
next month. Recently, the EPC project of Longhua Zhangkengjing affordable housing, a concrete modular high-rise building in China, has completed structural capping and will be completed and delivered by the end of next month. The project consists of five high-rise buildings of nearly 100 meters, which are assembled by 6028 independent module units, and takes only one year from start to completion. Longhua Zhangkengjing Security Housing Project adopts the concrete MiC (Modular Integrated Construction) technology originally developed by China Construction Hailong Science and Technology. This technology is a highly integrated, new and efficient building form that integrates all building elements such as structure, interior and exterior decoration, electromechanical, water supply and drainage, heating and ventilation, etc. Factory production and on-site construction are parallel, which can effectively reduce construction pollution and save resources and energy while greatly improving the construction speed. In addition, standardized, refined and intelligent production management also guarantees the quality of the project. Compared with traditional construction methods, it can save more than 70% of on-site labor, reduce more than 75% of construction waste and more than 25% of material waste.
Last week, the national concrete price index closed at 138.73 points, flat on a month-on-month basis, down 7.28% year-on-year. Regionally, concrete prices in all provinces and cities in China have maintained stable operation. In
the next ten days, the accumulated precipitation in most areas of the south of the Yangtze River, most areas of the south of the central and southern China, the south of Sichuan, Chongqing, Guizhou, Yunnan, and the southeast of the Xizang will be 40 to 70 millimeters, and in some areas, 80 to 160 millimeters; the accumulated precipitation in the eastern part of Northwest China and the eastern part of the Qinghai-Xizang Plateau will be 15 to 30 millimeters; The precipitation in most of the above-mentioned areas is close to the same period of the year, among which the precipitation in the western and northern parts of Jiangnan, Yunnan and the western part of Guizhou is 30-60% more than that in the same period of the year, and the local precipitation is more than twice as much.
To sum up, the precipitation in China will decrease next week, and the impact of rain weather on construction activities will be weakened. The construction intensity of downstream infrastructure and municipal projects is expected to increase, but the demand for housing construction is still weak, dragging down the demand for concrete market, and the overall shipment volume shows a slight upward trend. At the same time, the price of raw materials in the upstream has stopped falling and rebounded, and the cost support has gradually stabilized. On the whole, the concrete market will recover slightly next week, and the quotations of enterprises are mainly stable.
