Abstract

The invention discloses durable concrete for wall columns. The concrete is prepared from components of raw materials as follows: Portland cement, coarse sand, medium-coarse sand, gravel, water, mineral powder, coal ash, natural zeolite ultrafine powder, a polycarboxylate water reducer, stannous chloride, sodium chromate, calcium nitrate, acetamide, ethylene glycol, lignin salt, alkylbenzene sulfonate, triterpenoid saponins, sodium hexametaphosphate, citric acid, polyvinyl alcohol fibers, glass fibers and polyisobutene fibers. The durable concrete for the wall columns has the advantages of being high in strength, good in durability, wide in application range and the like.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to durable concrete for wall columns. Background technique [0002] Concrete is the most used building material today, and high-performance concrete represents the development direction of concrete technology. The wall column is an important part of the construction project. It bears the force of the entire construction project. As the main structure of the entire construction project, the quality requirements are very high. Concrete is one of the main construction materials in the wall construction process. The quality of the concrete material has a serious impact on the construction quality of the wall column, and affects the service life and use function of the project. Currently, the durability of concrete used for wall studs has yet to be improved. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention propose...
