Year-on-year decrease 3.
Cambridge, in collaboration with companies, have developed the first 3D printed concrete infrastructure component for a national highway project. The component is a type of retaining wall known as a "head wall", which has been installed on the A30 motorway in Cornwall. Sensors are embedded in the retaining wall structure, which can provide real-time information, including measured data of temperature, strain and pressure. This "digital twin" wall can help find and correct potential faults. By using 3D printing technology, the team designed and built a curved hollow wall without formwork and steel reinforcement, and the strength of the wall comes from its own geometry. Walls are manufactured using 3D printing technology, resulting in significant savings in costs, materials and carbon emissions. This
week, the national concrete price index closed at 131.26 points, down 0.20% from the previous month and 8% from the previous year. Regionally, the price of concrete in Hunan and Hubei markets has been reduced by about 20-30 yuan per square meter. Local concrete prices in Guangxi, Zhejiang and Jiangsu have been reduced by 5-10 yuan per square meter, while concrete prices in other provinces and cities in China have generally remained stable. In
the next ten days, the main rain areas will be located in the southeastern part of central and southern China, the eastern part of Jiangnan, Jianghuai, Huanghuai, the eastern part of North China, the southern part of Northeast China, the Yunnan-Guizhou Plateau and the southern part of the Xizang, with a cumulative precipitation of 60-100 mm in most areas, 120-200 mm in some areas and more than 300 mm in the southeastern coastal areas; The precipitation in most of the above areas is 3 to 70% more than that in the same period of the year, and 1 to 2 times more in some areas. In terms of temperature, high temperature weather in China mainly occurs in Xinjiang Basin, western Gansu, western Inner Mongolia and other places, with the highest temperature generally ranging from 35 to 38 ℃, and locally above 40 ℃; there is no persistent significant high temperature weather in the central and eastern regions of China.
To sum up, the domestic precipitation will increase significantly next week, the local high temperature will continue, the downstream construction intensity will be limited, the construction projects will continue to advance slowly, in addition, the social funds are still tight, the demand increment is insufficient, the supply of enterprises is more cautious, so the market concrete shipments will continue to maintain a low level. At the same time, the price of raw materials in the upstream continues to fall, and the cost side is difficult to form an effective support. Overall, the concrete market will continue the downward trend of weakness next week.
