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 →
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 →
Q: What is gypsum-based mortar? A: Gypsum-based mortar is mainly composed of hemihydrate gypsum coupled with corresponding auxiliary materials and chemical admixtures, made by uniform mixing. In terms of using performance, generally it can be divided into gypsum-based plastering mortar for wall plastering and gypsum-based self-leveling mortar for ground leveling. Q: What is.. read more →
Gypsum putty is also known as wall scraping putty, a powdery material with building gypsum powder and talcum powder as main materials, mixed with a small amount of gypsum modifier. When using it, add water to stir evenly and level the wall by blade coating. It is the ideal base material for spraying coating and.. read more →
The properties of plastering mortar after hardening include the compressive strength, bond tensile strength, contraction, permeability resistance and frost resistance. Plastering mortar has requirements for appropriate compressive strength, high bond tensile strength and low contraction, as well as good permeability and frost resistance if used for exterior walls. The compressive strength should try to match.. read more →
The use of plastering mortar should be determined by the facade dimensional precision and wall structure of buildings. For example, since the brick structure wall has many mortar joints between blocks and large dimensional deviation of blocks, ordinary plastering mortar is usually used. As for reinforced concrete structure, if the dimensional accuracy deviation of template.. read more →
The performance of mortar before hardening is the operability of mortar, specifically manifested in the consistency, layering degree, water retention, density and setting time. The consistency index reflects the softness of mortar. If the consistency is great, mortar will be soft and easy for spreading; if the consistency is small, mortar will be relatively.. read more →
In the formulations of building materials, the dosage of cellulose ether is only 0.1% to 1%. But it plays an irreplaceable role. Various applications of cellulose ether in building materials will be introduced as follows. 1. Latex and Latex Building Materials Such cellulose derivatives as MC, CMC, HEC and HPMC can be used in the.. read more →
Q: What is the cementing material? And what types? A: Cementing materials are generally divided into two categories, inorganic and organic cementing materials. The cementing material generally used in buildings refers to the inorganic cementing material. It refers to such a category of inorganic powder material as is mixed with water or the aqueous solution.. read more →
