China Construction Commercial Concrete insists on taking innovation as the engine, focusing on the cutting-edge technology of concrete, and promoting the continuous "innovation" of green low-carbon concrete. Since 2025, six scientific and technological achievements of the company have been successfully authorized by the State Intellectual Property Office.
1. A kind of low-carbon mass concrete and its preparation method
a technical achievement declared by China Construction Commercial Concrete, a kind of low-carbon mass concrete and its preparation method, has been authorized by the State Intellectual Property Office. This achievement adopts direct and indirect carbon reduction technology, through aggregate selection, mix proportion optimization, adding heat storage particles and other methods, to reduce the amount of fly ash and cement in concrete, reduce CO2 emissions, reduce the cracking risk of mass concrete caused by temperature stress, and generate low-carbon mass concrete with good construction performance, high strength, strong durability and not easy to crack.
2. A kind of heat-resistant low-carbon concrete and its preparation method
a technical achievement "a kind of heat-resistant low-carbon concrete and its preparation method" declared by China Construction Commercial Concrete Jiangsu Region has been authorized by the State Intellectual Property Office for invention patent. Under the synergistic effect of tuff powder, corncob ash and freeze-drying, a kind of refractory aggregate with closed outer surface and porous inner surface is obtained, and the heat-shrinkable fiber is used to improve the heat resistance and crack resistance of concrete at high temperature.
3 Preparation device and method
of recycled aggregate based on water jet crushing of waste concrete a technical achievement declared by Zhongjian Commercial Concrete, Preparation device and method of recycled aggregate based on water jet crushing of waste concrete, was authorized by the State Intellectual Property Office. This achievement invents a recycled aggregate preparation device based on water jet crushing of waste concrete, which comprises a high-pressure water pump, a longitudinal high-pressure water jet pipeline, a transverse high-pressure water jet pipeline, a recycled aggregate collection plate and a recycled aggregate grading mechanism, which can strip out the aggregate from waste concrete and waste reinforced concrete and carry out particle grading. Concrete with different properties is prepared according to different grades of recycled aggregate.
4. A kind of anti-seepage and anti-cracking mass concrete and its preparation method
, a technical achievement declared by China Construction Commercial Concrete Jiangsu Region, "a kind of anti-seepage and anti-cracking mass concrete and its preparation method", was authorized by the State Intellectual Property Office for invention patent. In this study, modified blast furnace slag powder, sodium acetate, expanded perlite water-absorbing aggregate and self-repairing polyvinyl alcohol fiber were used to improve the anti-seepage and anti-cracking performance of concrete.
5 a High Temperature Resistant Quench High Performance Concrete and Its Preparation Method
a technical achievement "a High Temperature Resistant Quench High Performance Concrete and Its Preparation Method" declared by Zhongjian Commercial Concrete Jiangsu Region has been authorized by the State Intellectual Property Office as an invention patent. By introducing temperature gradient composite aggregate, silicon carbide, plantain seed shell glue and other materials into concrete, the internal and external temperature gradient of concrete can be greatly reduced under high temperature and rapid cooling conditions, and the compactness and crack resistance can still be maintained at a high level, which can effectively solve the problem of cracking and strength acceleration caused by high temperature stress of concrete. And that service cycle life of the engineer structure is prolonged.
6 a kind of mass concrete based on construction waste and its preparation method
a technical achievement declared by China Construction Commercial Concrete, a kind of mass concrete based on construction waste and its preparation method, was authorized by the State Intellectual Property Office. This achievement uses high-pressure water jet to crush construction waste and further strengthen the surface to obtain recycled coarse aggregate, and the remaining liquid-phase part of the waste slurry residue is ultra-fine ground to obtain recycled waste slurry powder, which is combined with modified compound a gent to complete the preparation of mass concrete, so as to realize the resource utilization of construction waste. The obtained mass concrete has the advantages of low hydration heat, high strength, small shrinkage and the like, and has remarkable economic and environmental benefits.
