摘　　要：通过掺粉煤灰再生砂浆砖砌体与普通砂浆砖砌体在3种砂浆强度下的轴心抗压试验,观测砖砌体试件的变形和破坏特征,发现普通砂浆砌体和掺粉煤灰再生砂浆砌体弹性模量和应力应变关系较为类似,但掺粉煤灰再生砂浆砌体比普通砂浆砌体承载力偏低,脆性破坏更明显;参照《砌体结构设计规范》(GB 50003—2011)建议了掺粉煤灰再生砂浆砌体抗压计算式,旨在为后续相关的研究提供一定的参考。Three different mortar strength tests were performed for recycled masonry mortar incorporated with fly ash and ordina-ry masonry mortar. The deformation and failure characteristics of masonry specimens were evaluated. It was found that the elas-tic modulus and the relationship between stress and strain were similar for ordinary masonry mortar and masonry mortar recycled with fly ash.. The bearing capacity of recycled masonry mortar incorporated fly ash is lower than ordinary masonry mortar and its brittle failure is more evident. On the basis of ordinary masonry norms？ the compressive formula for recycled masonry mortar in-corporated with fly ash was proposed, which can provide a reference for subsequent researches.
