The role of masonry mortar is to make block materials bonded into a whole. Generally the strength of block material is higher than that of mortar. The block materials in the mortar of low strength are usually in the state of flexural and shear stress. For the structural failure of masonry, the block material is.. read more →

The consistency of wet-mixed masonry mortar is mainly determined by such factors as the type of block material, climatic conditions for construction, distance and conditions of transport, of which the type of block material is the main factor, related to the property and size of block material. If the block material is great in density.. read more →

The amount of water used for masonry mortar is 260-300 kg/m³, and the amount of cement used for traditional masonry mortar is 180-300kg/ m³. The main role of controlling the water retention rate is to ensure that too much moisture of mortar will not be absorbed by block materials before setting and hardening, and that.. read more →

The raw materials of masonry mortar mainly are cementitious materials, aggregates, admixtures and additives.   Cementitious Materials Cement is the main cementitious material of masonry mortar. Currently the most commonly used are ordinary Portland cement, slag cement and etc., but slag cement is easy for bleeding, it should be kept in mind during use. Since.. read more →

The density of building mortar refers to the mass density of a certain proportion of uniformly mixed and stirred cementitious materials, sand and water. As for the component materials of mortar, their respective density is as follows: the apparent density of lime putty (1350kg/m³) > the bulk density of cement (1280kg/m³) > density of water.. read more →
