Abstract

The invention discloses concrete for a building. The feed additive is prepared from the following raw materials in parts by weight: 80-100 parts of cement, 30-50 parts of river sand, 30-50 parts of gravels, 20-30 parts of fly ash, 5-10 parts of silicon oxide, 20-30 parts of steel fibers, 10-15 parts of a surface enhancer, 8-12 parts of calcium lignosulphonate powder, 8-12 parts of epoxy resin, 6-8parts of acrylic emulsion, 4-6 parts of rubber powder, 1-2 parts of an anti-rust agent, 3-5 parts of auxiliaries and 60-80 parts of water. Compared with the prior art, a certain amount of steel fibers are doped into the concrete, so that the tensile strength, bending resistance, cracking resistance, wear resistance, impact resistance, fatigue resistance, toughness and the like of the concrete canbe improved; the surface reinforcing agent is fully permeated; effective components of the water reducing agent can be quickly subjected to chemical reaction with free calcium in concrete, so that the compactness of the structure is improved, a firm solid like massive rock is formed on the surface layer of the concrete, the strength and the wear resistance of the surface layer of the concrete structure are greatly improved, and the concrete structure is permanently closed, firm, wear-resistant, free of dusting and capable of bearing larger loads.

Description

technical field [0001] The invention relates to the technical field of preparation of concrete for construction, in particular to concrete for construction. Background technique [0002] Concrete for construction is a general term for engineering composite materials in which aggregates are cemented into a whole by cementitious materials. Generally speaking, the term construction concrete refers to the cement concrete obtained by mixing cement with cement as cementing material, gravel and fine sand as aggregate, mixed with water in a certain proportion, and admixtures and admixtures can also be added. , also known as ordinary building concrete, is widely used in civil engineering. [0003] Most of the existing building concrete is made of simple cement, gravel, and fine sand mixed with water. The surface of the building concrete produced in this way is prone to cracks, low tensile strength, poor corrosion resistance, and poor toughness. For example, the Chinese patent appli...
