What's the effect of mixed mortar lime paste?
Improve workability and speed up the curing process. The setting time of some cements is also regulated by stone.
Lime paste in mixed mortar is a cementitious material (rigid cementitious material, the original lime mortar is also very good strength), resulting in strength. He has another role: good workability (i.e., workability of cement mortars). The utility model has the advantages of easy upper knife and high fullness of the masonry mortar. (specifications are not commonly used: if the upper masonry mix mortar to use cement mortar, should be improved than the mixture of mortar a strength grade. Why? Is lime paste stronger than cement? No! It is the mortar of the mixed mortar that has higher plumpness than the cement mortar. That is, it is easy to do so.
Why should the plastering of the inner wall plastering be layered? Now the plastering is mostly done by hand, and the body exerts limited pressure on the plastering layer. The ash layer thickness of the RCC is not solid, easy detachment. In addition, mortar sometimes has a hard cement material, too thick, unfavorable consolidation. The smoothness of the wall is also achieved by layer by layer. And the plastering layer has the consolidation contraction, and the layered construction will be beneficial to coordinate the shrinkage deformation.
