The additive is a generic term for a few materials which could change some properties of mortar, such as redispersible polymer powders (or emulsion), fibers, retarding agents, fluidizing agents, deformation agents for adjusting the volume of mortar, and water-repellent agents. The special performance that additives give dry-mixed mortar is the key to distinguish it from.. read more →

The redispersible powder is a special water-based emulsion made by spray drying and a polymer binder prepared mainly based on the vinyl acetate-ethylene copolymer. After partial evaporation of water, polymer particles form a layer of polymer film by agglomeration and play the role of adhesive. When redispersible polymer powder is used together with inorganic cementitious.. read more →

After redispersible polymer powder is added into cement mortar, the tensile strength and flexural strength of mortar will be significantly improved, while the compressive strength won’t get significantly improved, even declined. The reason is that the toughening effect of redispersible polymer powder has enhanced the internal tensile strength of mortar and the bonding tensile strength.. read more →

After dry-mixed mortar added with redispersible polymer powder is mixed with water, the modification of redispersible polymer powder on cement mortar is accomplished by redispersion of powder, hydration of cement and film formation of polymer. The film forming process of redispersible latex powder in mortar can be divided into three stages.   In Stage One,.. read more →

Redispersible polymer powders are polymer emulsions which have been converted by a series of process such as high temperatures and pressures, spray drying and surface treatment to powdered thermoplastic resin materials. When mixed with water, these powdered organic binders can redisperse in water back into new emulsions with essentially identical properties to the original copolymer.. 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 →

What is masonry mortar?

Dry-Mixed Mortar 0 Comment

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 →

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 →
