Abstract

The invention discloses a concrete formula and a preparation process. The concrete comprises the following components in percentage by weight: 20-35% of cement, 10-25% of fly ash, 5-15% of slag, 10-25% of straw powder, 2-6% of a thickening agent, 6-10% of lightweight aggregate, 3-8% of an expanding agent, 1-4% of a water reducing agent and 20-35% of water. The concrete disclosed by the invention has excellent concrete working performance, reflects the development direction of environment-friendly concrete, has excellent performances such as light weight and high strength, has an environment-friendly advantage, can absorb and consume a large amount of industrial and agricultural wastes, and has an environment-friendly significance; the added expansive agent can improve the strength of concrete in the later period, the concrete setting time is appropriately prolonged, the concrete further has characteristics of excellent high crack resistance, excellent seepage resistance and good adaptability, the added thickener solution molecules can be connected to form the net structure, the solvent and the other dispersion media are completely contained in the net structure, the whole system forms the non-fluidity semi-solid, and the viscosity of the concrete can be improved.

Description

technical field [0001] The invention relates to the field of concrete production, in particular to a concrete formula and a preparation process. Background technique [0002] Concrete refers to the collective name of engineering composite materials that use cementitious materials to cement aggregates into a whole. Generally speaking, concrete refers to using cement as cementitious material, sand and stone as aggregates; Aggregate) according to a certain proportion, the cement concrete obtained by stirring, also known as ordinary concrete, it is widely used in civil engineering. [0003] Concrete has the characteristics of abundant raw materials, low price, and simple production process, so its consumption is increasing. At the same time, concrete also has the characteristics of high compressive strength, good durability, and wide range of strength grades. These characteristics make it widely used. It is widely used not only in various civil engineering, but also in shipbuil...
