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 →

The traditional method of pasting tiles or stone is to adopt the on-site preparation, mixing cement, sand, 108 glue and water according to a certain proportion and then pasting. Since the water retention of mortar of this kind is low, tiles should be soaked and wetted in water beforehand, and then put mortar onto the.. read more →

①. It has good water retention. Tiles do not need soaking treatment before pasting, can be used in construction for a longer time and smeared in large area; it has good adhesion effects, strong vertical flow resistance, and the construction can be from top to bottom.   ②. Since it has good workability, slide resistance,.. read more →

The material composition of ceramic tile adhesive mortar generally includes: ①Cement: inorganic cementing material; ②Redispersible latex powder: enhancing the bonding strength for all substrates (especially non-porous substrates and large-size tiles; or pasted on the smooth surface and unstable substrates), increasing the tensile strength, reducing the elastic modulus, increasing the water retention, improving the workability, and.. read more →

The building gypsum is the main raw material that guarantees the bond strength of adhesive plaster, and should meet the requirements of national standard GB / T 9776-2008.   As for the setting time of building gypsum, the standard requires that the initial setting be greater than 6min and that the final setting be less.. read more →

Plastering mortar is a functional material rather than a structural material, and mainly plays the role of protecting the wall, in addition to leveling the wall. The quality of plastering mortar is ultimately reflected in its project quality. The main problems existing in plastering mortar are cracking, hollowing and shedding, for which a major reason.. read more →
