Effect of Polishing Brick Powder on Mortar Sorptivity and its Mechanism

摘要

In this study, the effect of polishing brick powder replacement cement slurry method on water absorption of motar is discussed. A series of mortar samples are prepared for testing water penetration amount at unit surface area with square of time and permeable porosity. The results show that the replacement of cement slurry with polished brick powder will increase the permeable pore of mortar and increase the sorptivity per unit area, thus effectively reducing the sorptivity of mortar at the same water cement ratio or strength.
