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 →
The tile adhesive mortar is the special adhesive mortar used for pasting ceramic wall and floor tiles, stone materials, etc., onto the substrate. According to the different composition, it can be divided into three broad categories: cement-based tile adhesive mortar, polymer emulsion tile adhesive mortar, and reactive resin tile adhesive mortar. The most commonly used.. 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 →
Floor mortar mainly has leveling, protective and decorative effects on the bottom floor and ground floor, and provides a solid and flat substrate for the floor. Floor mortar can be divided by purposes into screed mortar and surface mortar. Screed mortar mainly plays a role of leveling the ground, and should not contain lime ingredient.. read more →
What is adhesive mortar? A: Adhesive mortar is a kind of polymer reinforced cement-based ready-made dry-mixed adhesive mortar. It is made by mixing cement, quartz sand and polymer cementing materials with a variety of additives, has excellent flexibility and adhesion properties, as well as good sag resistance, water retention, water resistance, and easy operation,.. read more →
With the development of the cause of building decoration, in particular gypsum building materials continue to develop. For example, the construction of gypsum board used for partition within the wall requires the binder with a longer setting time; while the gypsum lines and decorative plaster used for construction requires the binder with a faster setting.. read more →
Most mortar is applied onto the surface of buildings, such as plastering mortar, floor mortar, waterproof mortar and decorative mortar, etc. Mortar has a very large contact area with the surrounding environment, so that the moisture in mortar is very easy to lose. In addition, the used site of mortar is not easy for conservation… read more →
