古建筑砌筑灰浆抗压强度试验研究

Experimental Study on Mortar Compressive Strength of Ancient Architecture

通过对4种不同成分组成的灰浆,采用试块法与回弹法对其抗压强度进行对比分析,并采用场发射扫描电镜对4种灰浆进行微观分析。试验结果表明,在灰浆中掺加适量的黄土、水泥等材料,能明显改善灰浆的抗压强度,微观分析的结果也印证了不同成分灰浆的抗压强度的变化;回弹法测试可以作为现场快速检测古建筑灰浆强度的手段得以应用。

Through the composition of four different compositions of mortar, by trial block method and re- bound method and carried out a comparative analysis of the compressive strength, and the field emission scanning electron microscopy （FESEM） of four kinds of mortars were microscopic analysis. Experimental results show that in the mortar mixed with appropriate amount of loess, cement and other materials, can significantly improve the compressive strength of mortar, microscopic analysis results confirm the compar- ative analysis of the compressive strength; rebound method to test can be as a site for the rapid detection of ancient building mortar strength means can be applied.
