根据现行设计规范,砌筑砂浆强度等级 M15、M10按试块的抗压强度平均值定义的砂浆在砌体设计规范中,没有提供参加设计的标准值。又根据 GB 50153-92(试行)当材料保证率为95%时,砌筑砂浆试配强度应为:f_(m,o)=f_(m,k)+1.645σ(保证率95%)式中:f_(m,o)——试配强度; According to the current design code, the masonry mortar strength grades M15 and M10, which are defined by the average compressive strength of the test block, do not provide design standard values ​​for masonry design specifications. According to GB 50153-92 (trial), when the material guarantee rate is 95%, the strength of masonry mortar test should be: f_(m,o)=f_(m,k)+1.645σ (guarantee rate 95%) Medium: f_(m,o)—Test intensity;
