Abstract

The invention relates to the field of buildings, in particular to concrete for the buildings. The concrete comprises the following components as raw materials in parts by weight: 80-100 parts of silicate cement, 60-80 parts of sulphoaluminate cement, 50-70 parts of phosphate cement, 40-60 parts of gravel, 50-80 parts of river sand, 5-15 parts of rubber powder, 4-15 parts of gypsum, 3-12 parts of plant fiber, 13-28 parts of polyvinylcarbazole, 1-6 parts of cubic boron nitride particles, 2-25 parts of polyvinyl ether, 3-18 parts of alkenyl succinic acid, 5-23 parts of petroleum sulfonate, 7-17 parts of anti-rust oil and 500-1000 parts of water. Through addition of the alkenyl succinic acid, the petroleum sulfonate and the anti-rust oil, the corrosion resistance of the concrete can be improved; through addition of the plant fiber, the tensile strength of the moulded concrete is improved; through addition of the cubic boron nitride, the hardness of the moulded concrete is improved; throughaddition of the polyvinylcarbazole, the heat preservation effect of the concrete is improved.

Description

technical field [0001] The invention relates to the construction field, in particular to concrete for construction. Background technique [0002] Concrete is one of the most important contemporary civil engineering materials. It is prepared in a certain proportion by cementitious materials, granular aggregates, water, and admixtures and admixtures added when necessary. After uniform mixing, dense molding, curing and hardening Concrete is a kind of artificial stone material that is formed. Concrete has the characteristics of rich raw materials, low price and simple production process, so its consumption is increasing. However, the current concrete still has the problems of low strength and poor corrosion resistance. Contents of the invention [0003] The object of the present invention is to provide concrete for construction, to solve the problems of low concrete strength and poor corrosion resistance. [0004] In order to solve the above-mentioned technical problems, the ...
