The continuous development of modern building construction technology and building materials industry has prompted people to develop high-performance, various special-purpose mortar to meet the requirements of construction, decoration, functionality and adhesion, flexibility and durability in the process of using mortar with different bases. In order to make the mortar meet the above special requirements, polymer … Continue reading
Due to the recent rebound of epidemic in Germany, travel restrictions to Germany have been tightened again. In order to ensure the safety and health of exhibitors and spectators, the organizers decided on October 13, 2020 to postpone the “2021 European Coatings Exhibition “, which will be held in Nuremberg, Germany, to hold it from … Continue reading
Natural cellulose fiber is widely used in dry mortar, such as production of tile adhesive, joint filling agent, dry powder coating, internal and external wall putty, interface agent, insulation mortar, anti crack plastering mortar, waterproof mortar and plaster, etc. Because natural cellulose fiber is a kind of natural fiber insoluble in water and organic solvent, … Continue reading
Natural cellulose fiber is one of the important additives in dry mortar products. It has been used since it was introduced into China in 1990s. At present, the largest one is the Arbocel cellulose fiber series produced by the German JRS company. Although some domestic manufacturers have begun to produce similar products, but due to … Continue reading
Recycled gypsum as a raw material for mortars such as gypsum plaster is hindered by significant prejudice and is not well accepted in the industry. Gypsum plaster with partial replacement by recycled gypsum also demonstrates that sustainability of construction materials is possible and represents another positive step toward circularity in construction. 1 Introduction Recycled gypsum … Continue reading
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
