不同底模对砂浆强度的影响

Effect of Different Bottom Formwork on Strength of Mortar

通过对不同底模的水泥砂浆试块和混合砂浆试块的强度试验研究,在相同稠度情况下,采用不同底模时,水泥砂浆强度比混合砂浆强度影响大。研究结果表明:钢底模比砖底模的离散性小;随着稠度变化,水泥砂浆采用钢底模比采用砖底模影响因素大,但混合砂浆采用钢底模比砖底模影响因素小。

The strength of cement mortar and mixed mortar with different bottom formwork were studied by tests.Results show that under the same consistency,the change of bottom mould has bigger influence on the strength of cement mortar than mixed mortar.Specifically,the discreteness of mortar strength with steel formwork is smaller than that with brick formwork.With the change of consistency,the cement mortar strength shows higher variation with steel formwork than with brick formwork.However for mixed mortar strength,the influence of consistency with steel formwork is smaller than that with brick formwork.
