在集料的表面水中溶解少量亲水性粉末状聚合物,可以减少喷射砂浆和混凝土在施工时的粉尘量。在集料的表面水中溶解亲水性聚合物后,可使集料表面形成一层具有粘性的表面
Dissolving a small amount of hydrophilic powdery polymer in the surface water of the aggregate can reduce the amount of dust that is sprayed on the mortar and the concrete during construction. After the hydrophilic polymer is dissolved in the surface water of the aggregate, a surface with a sticky surface can be formed on the surface of the aggregate.
