可再分散乳胶粉在新型自流平地面砂浆中的应用

Application of Redispersible Polymer Powders Based on a New Cementitious Self-leveling Floor Mortar

介绍三元胶凝体系在单组分水泥自流平砂浆中的作用机理,可再分散乳胶粉的添加对水泥自流平砂浆性能的影响。结果表明,配比合理的水泥三元胶凝体系能够有效地补偿水泥自流平砂浆的收缩,添加可再分散乳胶粉可以明显提高自流平砂浆的流动度、粘结强度、抗拉强度、抗折强度。

Introduced the function mechanism of ternary cementitious systems and effection of redispersible polymer powders based on a new cementitious self - leveling floor mortar. The result indicated that the allocated proportion reasonable ternary cementitious systems can compensate effectively contraction of cementitious self - leveling floor mortar, this redispersible emulsion powder could remarkably improve fluidity, adhesion strength, tensile strength and bending strength of the self -leveling materials.
