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 →
Aerated concrete is the porous structure, with many air vents inside. Pores of good quality are closed circular ones; while those of poor quality are continuous through pores. The porosity of aerated concrete is generally 65%-75%, with the maximum up to 80%. When the traditional laying method is used in construction, sintered solid clay.. 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 →
The selection principle of ready-mixed mortar is that the use of wet-mixed or dry-mixed masonry mortar is determined by the situation of project and surrounding suppliers of ready-mixed mortar. If wet-mixed masonry mortar is selected for use, then the consistency and water retention of wet-mixed mortar should be determined by the types of block materials;.. read more →
First, masonry mortar is required to have good operability, including liquidity, cohesion and thixotropy. The mortar with good operability can easily form a uniform thin layer on the surface of rough block materials, and can be tightly bonded with the bottom surface. The use of mortar with good operability can not only facilitate the construction.. read more →
Masonry mortar is an integral component used to bond bulk materials as a whole and constitute some desired functional properties together. Masonry mortar mainly plays a role in masonry construction, load transfer and deformation coordination, and is an important part of masonry structure. Although masonry mortar accounts for only a relatively small part of masonry.. read more →
