Powder concrete curing agent and preparation method thereof
The invention discloses a powder concrete curing agent and a preparation method thereof. The powder concrete curing agent comprises the following raw materials in percentage by mass: 40-60% of redispersible latex powder, 10-20% of polyvinyl alcohol powder, 15-30% of amorphous silicon dioxide, 1-5% of a tackifier PAM, 1-5% of ash calcium powder and 5-10% of cellulose ether. The powder concrete curing agent can effectively improve the water retention rate, the surface strength and the film-forming property of concrete, and is convenient to transport and simple to use.
本发明公开了一种粉体混凝土养护剂及其制备方法，其包括按质量百分比计的如下原料：可再分散性乳胶粉40％‑60％，聚乙烯醇粉末10‑20％，无定型二氧化硅15‑30％，增粘剂PAM1‑5％，灰钙粉1‑5％，纤维素醚5‑10％。本发明的粉体混凝土养护剂，可以有效提高混凝土的保水率以及表面强度和成膜性，且便于运输、使用简单。
