Description

Product Introduction:
Qiangnai Gypsum Plaster Mortar is a single-component, pre-mixed dry powder product precisely measured and uniformly mixed from low-energy modified semi-hydrated building gypsum, selected (lightweight) aggregates, and polymer-modified activators. After adding water according to the specified ratio and mixing evenly, it can be used for wall leveling construction, suitable for both manual and mechanized spraying construction.
 
Product Reference Standards:
GB/T 28627-2012 "Plastering Gypsum"
GB 6566-2010 "Limits on Radioactive Nuclides in Building Materials"
JC 890-2001 "Mortar for Masonry and Plastering of Autoclaved Aerated Concrete"
GB 18582-2008 "Limits on Hazardous Substances in Interior Wall Coatings of Interior Decoration and Renovation Materials"
 
Scope of Application:
Plastering gypsum is suitable for general plastering work on interior walls and ceilings of buildings, excluding damp areas such as kitchens and bathrooms. Lightweight plastering gypsum is suitable for plastering and leveling most base materials (autoclaved aerated concrete, lightweight partition boards, bricks, concrete, etc.). The conventional plastering thickness of plastering gypsum is 5mm~25mm, the minimum thickness of the finished plastering surface is 5mm, and the total thickness of ceiling plastering should be less than 10mm.
 
Main Advantages of the Product:
1. High coverage, reducing construction costs.
2. No need for water curing, reducing construction costs; labor and material saving construction, its weight is only half of traditional cement mortar;
3. Early strength and fast hardening, good volume stability, and guaranteed wall leveling quality;
4. Low density, effectively reducing building load;
5. Green, environmentally friendly, and safe;
6. Excellent fire prevention, heat insulation and heat preservation performance, energy saving and consumption reduction;
7. Regulates air humidity and creates a comfortable living environment;
8. It can attenuate sound pressure and prevent sound energy projection, and has good sound insulation performance.

High-ductility concrete

High-ductility concrete (HDC) is a special concrete product with high ductility and plasticity. Its main components include cement, aggregates, fibers, admixtures, and additives. The addition of fibers, its key core material, significantly improves its ductility, toughness, fatigue resistance, and impact resistance. It is suitable for structural reinforcement projects that require resistance to vibration and cracking, such as traditional buildings, modern buildings, and municipal engineering projects, to address the brittleness and poor crack resistance of traditional concrete.
