有底试模与无底试模对砂浆强度的影响

The effect of mould with bottom and without bottom to mortar strength

砂浆是砌体工程不可缺少的建筑材料,不同的行业关于砂浆的规定和要求不同,致使砂浆的质量控制标准不同。通过分别对有底试模和无底试模成型水泥砂浆和水泥混合砂浆试件的抗压强度进行对比,说明试模类型对砂浆抗压强度的影响,并提出根据工程实体的实际情况选择砂浆试模的类型。

Mortar is an essential building materials for masonry engineering,but the requirements of different industries on the mortar are different,resulting in the mortar quality control standards are different.Through the compressive strength comparing test for cement mortar and cement composite mortar with mould with bottom and mould without bottom,it shows that the type of mortar mould has effects on mortar compressive strength,and we should choose the type of mortar mould according to the actual engineering situation.
