Abstract

The invention discloses concrete with performance improved by using a BTC (bis-trichloromethyl carbonate) functional admixture. The concrete comprises the following components in parts by mass: 200-320 parts of cement, 60-90 parts of mineral powder, 40-60 parts of fly ash, 680-780 parts of sand, 1060-1100 parts of broken stones, 3.3-4.74 parts of a concrete admixture, 1.92-2.58 parts of the BTC functional admixture and 170 parts of water. The BTC functional admixture can improve the cohesiveness of the concrete, reduce the bleeding and segregability of the concrete and enhance the fluidity of the concrete, so that the service life of a pump pipe is prolonged, the use of a cementing material in the concrete is reduced, the cost of the concrete is lowered, the workability of the concrete is improved, and the concrete is convenient to construct.

Description

technical field [0001] The invention relates to a concrete whose performance is improved by using a BTC functional admixture, and belongs to the technical field of concrete. Background technique [0002] At present, commercial concrete is a high-tech product combining modern concrete and modern construction technology. In order to make commercial concrete stable, economical and cost-effective, it is necessary to strictly select the required raw materials and optimize the concrete ratio. On the one hand, because concrete companies are limited by the quality of local sand, stone and other raw materials, it is difficult to reduce production costs while satisfying the performance of concrete. Reducing costs without sacrificing concrete quality is a challenge for companies. Applying new materials and new technologies is a good way to solve problems. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the...
