Description

【Technical field】 [0001] The invention belongs to the technical field of preparation of concrete for construction, and in particular relates to a formula of 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 exam...
