砌体材料强度等级评定和砂浆试配强度确定

Assessment of Masonry Material Strength Level and Determination of Mortar Trial Strength

本文简要介绍砌体材料强度等级规定和评定方法,通过讨论砂浆强度等级规定和评定,对砂浆强度等级建议按照砂浆的标准强度划分等级,对砌筑砂浆试配强度计算式以及水平灰缝饱满度和砂浆强度保证率的关系提出商榷并进行探讨。

This article introduces chiefly the strength level requirements and evaluation methods of masonry material. Through the discussions on mortar strength level requirements and assessment, the author suggested that the classification of mortar strength level should be in according with the standard strength of mortar. This article further discussed the calculation equation of mortar trial strength, the relation between horizontal joint fullness and mortar strength guaranteed rate.
