Abstract

The invention discloses a concrete preparation process. The concrete preparation process is characterized by specifically comprising the following steps of S1, preparing raw materials: taking the following raw materials in parts by mass: 400-550 parts of cement, 60-90 parts of fiber filler, 12-15 parts of retarder, 600-750 parts of sand, 30-45 parts of additive, 80-100 parts of silicon powder, 80-110 parts of fly ash, 50-80 parts of surfactant and 300-350 parts of water, S2, material crushing: fully mixing the cement, the fiber filler, the silicon powder and the fly ash in parts by weight, andthen putting the mixture into a crusher to be crushed to reach the use specification, and S3, primary stirring and mixing: selecting the crushed cement, fiber filler, silicon powder and fly ash and uniformly mixing with water and sand which are proportioned in parts by weight. The fiber filler can effectively control microcracks caused by factors such as plastic shrinkage, air shrinkage and temperature change of the concrete, and the anti-cracking and anti-seepage performance and the anti-impact and anti-abrasion performance of the concrete are improved.

Description

technical field [0001] The invention relates to the field of concrete preparation, in particular to a concrete preparation process. Background technique [0002] Concrete, referred to as "concrete" for short: refers to the collective name of engineering composite materials in which aggregates are cemented into a whole by cementitious materials. Generally speaking, the term concrete refers to the cement concrete obtained by using cement as the cementitious material, sand and stone as the aggregate; mixed with water (may contain admixtures and admixtures) in a certain proportion, and stirred. Concrete, which is widely used in civil engineering. [0003] For example, the Chinese patent whose authorized announcement number is CN111592283A discloses a commercial concrete and its preparation process, which belongs to the field of building materials and is used for building construction. It solves the problem of cracks in existing concrete. According to the weight percentage, it i...
