High-fluidity concrete additive and preparation method thereof
The invention relates to a high-fluidity concrete additive and a preparation method thereof. The high-fluidity concrete additive comprises a surfactant material and coal ash. The preparation method comprises the step of adequately mixing boiling coal ash with an atomized surfactant solution. According to the high-fluidity concrete additive, the fluidity and the gradual fluidity of concrete can be improved, the activity index of coal ash can be improved, and the adaptability of a water reducer can be improved; the high-fluidity concrete additive is low in cost and easy to prepare and is particularly applicable to pump concrete or self-compacting concrete with relatively high requirement for fluidity.
