Wood fiber is widely used in dry powder mortar, such as tile adhesive, jointing agent, dry powder coating, interior and exterior wall putty, interface agent, insulation mortar, anti-cracking plaster mortar, waterproof mortar and plaster plaster. Because wood fiber is a natural fiber insoluble in water and organic solvents, it has excellent flexibility and dispersibility. Adding … Continue reading
In recent years gypsum has been used more and more widely in the construction engineering, and the use of gypsum based dry mortar has become the main product of dry mortar. For example, as the interior wall plastering material, plastering gypsum has the functions of light weight, anti-inflammatory, sound insulation, heat preservation, sound absorption, etc. … Continue reading
Applying RDP into mortar is actually the modification of ordinary mortar, also known as polymer modified cement mortar. Through polymer modification, the brittleness, high elastic modulus and other weaknesses of traditional cement mortar are improved; the cement mortar is endowed with better flexibility and tensile bond strength to resist or delay the generation of cement … Continue reading
AbstractDamp masonry is a threat to architectural structures while also posing ahygienic problem to living conditions in the building’s interior. ydrophobicagents have been the preferred method for protecting masonry facades and building surfaces against moisture entry and weathering. Early water repellent systems had to be externally applied on finished constructed parts and outside structures. Such … Continue reading
Cementitious building materials such as concrete, mortar, and masonry tend to readily absorb water because of their pore and capillary structure. To prevent damage due to moisture absorption, the material’s absorbency can be reduced by the application of a water repellent sealer. Silanes and siloxanes, the two most common types of water repellents, are both … Continue reading
Moisture can do irreparable damage to gypsum building materials. To prevent this and to protect the set gypsum mortar against moisture, powder-form water-repellent agents are admixed to the dry-mix mortar. This requires manufacturers of standard powder-form water repellents to employ carrier or encapsulation materials as a way of converting the liquid active ingredients into a … Continue reading
ANTI CRACK FIBER Anti crack fiber is a new type of fiber of concrete and mortar which is composed of polypropylene and polyester. It is called secondary reinforcement of concrete. With the development of composite materials, anti crack fiber has been widely used in civil engineering. The results show that when the crack resistant fiber … Continue reading

Currently the most widely used RDP are EVA and Veova. The technology is mature and the application effect is good. In recent years vinyl acetate acrylic acid system has emerged as the focus of foreign competitive research and development, but it has not been widely used due to its immature technology, but its excellent comprehensive … Continue reading
