风旋砂对普通干混砂浆性能影响的试验研究

Experimental study on the effect of wind-spinning sand on the properties of ordinary dry mixed mortar

本文主要研究风旋砂在普通干混砌筑和抹灰砂浆中的应用,主要研究风旋砂对普通干混砌筑和抹灰砂浆的性能(保水性、抗压强度和拉伸粘结强度等)的影响。结果表明:在满足普通干混砂浆工作性能及力学性能条件下,风旋砂可以应用于普通干混砌筑和抹灰砂浆中。

This paper mainly studies the application of wind-spinning sand in ordinary dry-mixed masonry and plastering mortar,and mainly studies the effect of wind-spinning sand on the properties(water retention,compressive strength and tensile bond strength,etc.)of ordinary dry-mixed masonry and plastering mortar.The results show that wind-spinning sand can be used in ordinary dry-mixed masonry and plastering mortar under the condition of satisfying the working and mechanical properties of ordinary dry-mixed mortar.
