Abstract

The invention discloses concrete and a preparation method thereof. The concrete is prepared from 2-20 of cement, 1-10 of fly ash, 1-10 of mineral powder, 2-50 of sand, 20-70 of stone, 0.1-10 of a water reducing agent, 0.01-20 of a synergist and water. The concrete is mixed with the synergist, so that the pore structure of the concrete is improved effectively, the compactness of the concrete is improved relatively, water permeability is reduced, and capacities such as anti-permeability, antifreezing property, chemical resistance, rust resistance and the like of the concrete are improved; besides, after mixing with the synergist, bleeding and segregation phenomena of a concrete mixture can be relieved, the setting of the concrete mixture is delayed, cement hydration heat emission speed is reduced, and the probability of cracks caused by inside and outside temperature differences is reduced; cement particles are effectively dispersed and particle surfaces are wetted sufficiently by water, so that the hydration area of the cement particles is increased, hydration is more sufficient, and concrete strength is improved.

Description

technical field [0001] The invention relates to the field of civil engineering materials, in particular to concrete and a preparation method thereof. Background technique [0002] Concrete, referred to as "concrete (tóng)": refers to the general designation of engineering composite materials that use cementitious materials to cement aggregates into a whole. Aggregate; mixed with water (may contain admixtures and admixtures) in a certain proportion, the cement concrete obtained by mixing is also called ordinary concrete, which is widely used in civil engineering. [0003] The cement industry is an industry that consumes a lot of resources and energy, and is a major emitter of greenhouse gases. The energy and resource consumption of cement production accounts for a large proportion of the entire industrial consumption and resource consumption. Cement is currently the most widely used building cementitious material. As the concrete industry with the largest amount of cement,...
