Problems solved by technology

[0002] Concrete is the most widely used building material in modern times. Simple concrete has poor performance, and admixtures need to be added to improve performance. Existing concrete admixtures can improve the water resistance of concrete, control the setting time, entrain air, dye, and improve the durability of concrete. Sex, but the performance is single, can not meet the demand

Abstract

A concrete admixture is composed of by weight, 20-30 parts of water reducer, 10-20 parts of silane coupling agent, 20-30 parts of polyhydroxybutyrate, 3-7 parts of defoamer, 10-15 parts of air entraining agent, 5-10 parts of hydroxypropyl ethyl cellulose, 5-8 parts of calcium formate and 3-8 parts of polyethylene glycol. The concrete admixture is easy to prepare, the raw materials are green and environmentally friendly, the water retention property, fluidity and durability of concrete can be effectively improved, the strength of the concrete is improved, and separation is reduced.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a concrete admixture. Background technique [0002] Concrete is the most widely used building material in modern times. Simple concrete has poor performance, and admixtures need to be added to improve performance. Existing concrete admixtures can improve the water resistance of concrete, control the setting time, entrain air, dye, and improve the durability of concrete. Sex, but the performance is single, which cannot meet the demand. Contents of the invention [0003] Purpose of the invention: In order to overcome the above disadvantages, the present invention provides a concrete admixture, which can improve the comprehensive performance of concrete, and has a simple proportion and green raw materials. [0004] Technical solution: The invention discloses a concrete admixture, the raw materials of which include by weight components: 20-30 parts of water reducing agent, 10-20 ...
