本文从水泥基自流平砂浆的工作性能、力学性能考虑,选择适宜凝结时间和强度的水泥,并通过正交试验选择合适的外加剂,进而又引入了重钙和石膏等掺合料,调配出了一种新型水泥基自流平砂浆。此种自流平砂浆流动度大、经时损失小、收缩率低、表面光洁、耐磨性能优良。本文可指导自流平砂浆的生产,使经济效益最大化。 Based on the workability and mechanical properties of cement-based self-leveling mortar, the cement with suitable setting time and strength was selected and the suitable additives were selected by orthogonal test. Then, the admixture of gypsum and gypsum was introduced into the cementitious self-leveling mortar. A new cement-based self-leveling mortar. The self-leveling mortar has high fluidity, small loss over time, low shrinkage, smooth surface and excellent abrasion resistance. This article can guide the production of self-leveling mortar to maximize economic benefits.
