Three, sand and gravel aggregate industry this week dynamic
1, annual output of 17 million tons! The project is located in Duwafang Village, Dinosaur Mountain Town, Lufeng City, Chuxiong Prefecture, with 41296
reserves of 210.8 million tons per year! The project includes two projects of soil environment improvement and waste gravel resource reuse, which are invested and constructed by Ningxia Golden Grape Agriculture and Forestry Science and Technology Co., Ltd., in which the waste gravel resource reuse project is to use the natural gravel produced in the process of land consolidation to produce construction aggregate and machine-made sand. The construction scale of each station is three 150t/H aggregate production lines, with an annual treatment capacity of 3.6 million tons of gravel, and the three temporary treatment stations have a total treatment capacity of 10.8 million tons per year.
3.2 billion yuan!
4. Comments on
the dynamics of the concrete industry this week 1. Striving for the progress of spring scenery, the recovery rate of Chongqing's high-speed rail projects reached more than
90% on February 5, 2023. Six high-speed railways in Chongqing, including Chengdu-Chongqing Middle Line, Chongqing-Wanzhou, Chongqing-Kunming, Xikun and Chengdu-Wanzhou, entered the construction climax immediately after the festival. More than 900 high-speed rail project sites in Chongqing have resumed production at more than 820 project sites, with a recovery rate of more than 90%, and more than 30000 construction workers have resumed production.
2. The world's first application
of prestressed concrete-filled steel tubular lattice tower for wind turbines has been completed. Recently, in Leling City, Dezhou City, Shandong Province, the world's first 165-meter-high prestressed concrete-filled steel tubular lattice tower prototype project has been installed. The tower breaks through the key scientific problems of the complex stress mechanism of the corner steel tube concrete component, the fatigue damage mechanism of the node, the failure mechanism of the whole structure under the coupling load of compression, bending, shear and torsion, and the like, The analysis method of concrete filled steel tubular (CFST) members under uniaxial cyclic loading and compression-bending-shear-torsion coupling loading is established, the analysis method of fatigue performance of T-shaped tube-plate joints of CFST stiffening rings is proposed, and the refined and efficient calculation method of prestressed concrete-filled steel tubular lattice tower structure is established. It is estimated that the prototype will generate more than 12.4 million kilowatt-hours of clean electricity annually, save about 0.4 million tons of standard coal, reduce carbon emissions by about
1.3. The Housing and Urban-Rural Construction Bureau of Dongguan City, Guangdong Province, issued the Notice on Several Measures to Strengthen the Management of Ready-mixed Concrete Industry, which calls for severe punishment of enterprises that fail to meet the quality standards and cracking down on the illegal supply of ready-mixed concrete, so as to promote the healthy and orderly development of the city's ready-mixed concrete industry. The competent construction department will take the qualified rate of concrete entity core-pulling strength as the benchmark, and make statistics on the results of concrete entity core-pulling strength at the construction site every year according to the ready-mixed concrete enterprises supplied, so as to manage the quality risk of enterprises at different levels.
This week, the national concrete price index closed at 140.01 points, down 0.06% month-on-month and year-on-year. 9. Regionally, the price of concrete in Chongqing market was reduced by 10 yuan per square meter, while the price of concrete in other provinces and cities in China remained stable. In
the next ten days, there will still be more rainy weather in the southern region, but the intensity will be significantly weakened in the later period. There will be 30-50 mm precipitation in Jianghuai, southern Jianghan, Jiangnan, northern Guangdong, Eastern Guizhou, southwestern Hubei, southeastern Chongqing and southeastern Xizang, and 60-90 mm precipitation in the north-central part of Jiangnan; In addition, the accumulated precipitation in northwestern Xinjiang, southeastern Qinghai, eastern Northwest China, central and southern North China, eastern Northeast China, Huanghuai and other places is 5 to 15 millimeters, and 20 to 30 millimeters in some areas; most of the above areas are 50 to 2 times more than same period of the year, and 30 to 70% less in southeastern central and southern China and southeastern Jiangnan. In terms of temperature, the average temperature in the north-central part of Xinjiang, the northern part of North China, the southern part of Northeast China, the south-central part of the Qinghai-Xizang Plateau and most parts of Yunnan is 1 to 2 degrees higher than that in the same period of the year, the average temperature in the central part of Inner Mongolia, the northwestern part of Sichuan and the southwestern part of the Xizang is more than 4 degrees higher, the temperature in Jianghuai, Jianghan and the western part of Jiangnan is about 1 degrees lower, and the temperature in most other parts of China is close to that of the.
To sum up, the precipitation in the south will gradually weaken next week, and the construction conditions are expected to improve. At present, workers have begun to return to work one after another, and the construction progress of some key projects has been accelerated. However, the situation of capital shortage in the downstream real estate industry has not been significantly alleviated, and the market demand will remain weak in the short term. In terms of cost, the price of upstream raw materials has maintained a weak adjustment trend in the near future, and the support for concrete prices is fatigue. On the whole, the concrete market demand will maintain a slow recovery trend next week, and the concrete price will be weak and stable.
