Fourth, the concrete industry this week's dynamic comments
1, Sifang New Material: renewed business license, new business scope
on April 4, the announcement of Sifang New Material showed that. Chongqing Sifang New Materials Co., Ltd. held the first extraordinary general meeting of 2023 on March 15, 2023, deliberated and passed the Proposal on Amendment, and approved the company's new business scope of manufacturing and sales of commercial concrete prefabricated components and research and development and promotion of new material technology. Recently, the company has completed the registration procedures for industrial and commercial changes and obtained the business license renewed by Chongqing Market Supervision and Administration Bureau.
2. Qingdao University of Technology overcomes the problem
of marine concrete corrosion inhibition. Inspired by "lotus leaf does not touch water", Professor Li Shaochun, School of Civil Engineering, Qingdao University of Technology, jointly developed a bionic super-hydrophobic coating to put on a layer of "waterproof clothing" for concrete. This kind of "waterproof clothing" can not only solve the problem of basement seepage on land, but also solve the problem of ion permeation-microbial coupling corrosion inhibition of marine concrete, which can significantly improve the durability of marine concrete structures. Related technical products have been applied in Qingdao Metro Line 1, Sino-German Eco-Park, Qingdao International Academician Port and Xinxing Heavy Industry Group (Regional) Headquarters Phase I Project.
3. CSCEC Western Construction successfully completed the concrete pouring
of "the first traction pipe curtain in China". Recently, the concrete pouring of "the first traction pipe curtain in China" project of Xi'an Xianyang International Airport Phase III Expansion Project, which was supplied by Qinhan Factory of CSCEC Western Construction North Co., Ltd., was successfully completed. The pipe curtain in this construction is an important structure of the connecting area between the pipe gallery and the subway in the third phase of the airport project. C35 self-compacting concrete is used, and the backward back pressure pouring method is used for pouring. The location and size of the grouting hole, the overflow hole and the exhaust hole are simulated and calculated for many times, so as to ensure that the concrete in the whole pipe cavity is filled densely. Faced with the complex working conditions on site, the concrete tanker can not reach the construction area of the pipe curtain, the pumping span is 37 meters, and the pressure of the pump truck needs to meet the requirements of concrete pumping, the company has formulated a special pumping plan. According to the comprehensive factors such as the length, angle, aperture size and internal stirrup distribution of the pipe roof structure, the grouting pressure is accurately calculated, and the relay mode of using the roof pump and the truck-mounted pump is finally determined, and the project is guided to rationally arrange the truck-mounted pump pipeline, use the high-pressure pump and the high-pressure pump pipe, and minimize the pumping pressure loss.
This week, the national concrete price index closed at 140.31 points, up 0.02% month-on-month and down year-on-year. 6. Regionally, the local concrete price in Guangdong increased by 5 yuan per square meter, while the concrete price in other provinces and cities in China remained stable. In
the next ten days, the main precipitation periods will be 10-12 and 13-15 days, and the cumulative precipitation in northern Jiangnan, southern Guizhou, coastal Guangdong and southeastern Xizang will be 25-50 mm, of which parts of northern Jiangnan can reach 60-90 mm; In the northern part of Xinjiang, the middle and eastern part of Inner Mongolia, the southeastern part of Northwest China, the eastern part of North China, Northeast China, Huanghuai and other places, the precipitation is 5 to 20 mm, and the local precipitation is more than 30 mm; the precipitation in these areas is 2 to 50% more than that in the same period of the year, and the local precipitation is about twice as much. In terms of temperature, the average temperature in most areas north of Huanghuai is on the low side, while the average temperature in northern Xinjiang, eastern Northwest China, central and Western Inner Mongolia, northwestern North China, parts of southern Northeast China, southern Jiangnan and northern Guangdong is on the low side of 1-2 C and 3 C locally, while the average temperature in most other areas of China is close to the same period of the year. The average temperature in parts of Southwest China, Jianghan and Northwest Jiangnan is 1 to 2 degrees higher.
To sum up, the domestic rainfall will be significantly reduced next week, and the construction conditions will be improved compared with the previous period. Affected by this, the construction intensity of downstream projects is expected to rebound, and the shipment volume of concrete market will gradually increase. At present, orders for mixing stations in most areas are still concentrated in infrastructure and municipal projects, and housing construction projects are only partially improved, which makes it difficult to form an effective support for demand in the short term. In terms of cost, the price of cement and sand aggregate has dropped slightly recently, and the pressure on the cost side has weakened slightly. On the whole, the price of concrete market will remain stable next week, with a slight increase in some areas.
