Basic Properties of Masonry Cement Mortar Affected by Content of Stone Powder

Abstract:

Article Preview

Experiments were carried out to study such basic properties as workability and strength of masonry cement mortar affected by mass content of cement equally replaced by stone powder. The mortar was designed in strength grade of M20 with three kinds of mix proportions, three replacing ratios of cement by stone powder. The results show that part of cement equally replaced by stone powder irregularly influences consistency and layering of fresh mortar but still brings fresh mortar into better workability; the optimum mass content of cement equally replaced by stone powder relates to the water to binder ratio of mortar, which are 5 %, 10 % and 15 % successively corresponding with 1.0, 0.9 and 0.8 water to binder ratio. Comprehensively concerned about the ratio of bending to compressive strengths of mortar, the referenced mix proportions of mortar with stone powder are proposed for application in practices.
