摘　　要：本文对同一龄期和同一设计强度等级的砂浆强度,采用各种砂浆强度检测方法进行检测评定,通过分析实际工程的检测数据,进行对比研究;对不同龄期、不同设计强度和不同砌体砖约束条件下的砂浆,采用各种砂浆强度检测方法进行检测,通过分析试验数据,进行对比研究。根据对比结果,结合实际检测鉴定操作经验,对砂浆强度的评定结果存在偏差的原因进行分析,提出了砂浆强度检测与评定的建议方法。According to the test data of some projects, using different but ordinary test methods, the assessing and comparing analysis of the mortar strength results, which are limited in the same age and designed strength grade, are carried out. At the same time, according to the experiment data, using different, ordinary test methods and different kinds of bricks, the assessing and comparing analysis of the mortar strength results, which are including different ages, designed strength grades and confining conditions, are presented. The reasons of influence on testing mortar strength are analyzed in response to comparing analysis results and actual testing experience, then some suggestions of choosing testing and assessing methods on mortar strength are also suggested.
