Description
Technical field
The present invention relates to concrete additive technical field more particularly to a kind of environment-friendly concrete water-reducing agent and its preparation sides
Method.
Background technique
In recent years, the capital construction in China has been introduced into the stage of high speed development, indicates the great of urban modernization
Foundation engineering scale is unprecedented, none is not closely bound up with concrete for the development of these great architectural engineerings, and the performance of concrete is good
The bad superiority and inferiority that directly decide construction engineering quality.Conventional concrete is to make cementitious material with cement, and sand, masonry gather materials, with water
Cooperate by a certain percentage, a kind of construction material obtained from agitated, apply in practical projects, this kind of material often exposes
In various more harsh environment, the service life of concrete is caused to decline, it is in addition with the improvement of people's safety consciousness and existing
For increasing for architectural engineering particular/special requirement, high intensity, high fluidity, high-durability, high permeability resistant energy also proposed to concrete
Deng the higher requirement of update.Therefore, the method for seeking to improve the comprehensive performance of concrete becomes focus of attention in the industry.
It is the effective ways for improving concrete performance that concrete additive is added in concrete, and water-reducing agent refers in coagulation
Under conditions of native workability, cement consumption are constant, mixing water amount, the additive for improving concrete strength can be reduced；Pass through table
Face active function, complexing, electrostatic repulsion forces or steric repulsion power etc. hinder or destroy the flocculent structure of cement granules, from
And it while saving cement consumption, can guarantee the workability of concrete and a kind of concrete additive of intensity.However, existing
There is the concrete in technology at high cost with water-reducing agent, complex manufacturing technology, method to be not easy to grasp, product qualified rate obtained it is low,
