Dry-mixed mortar or dry mortar is made of cement, sand, mineral and functional additives, mixing together proportionally. It is often in powder or granule form pre-mixed in special factory and transported to construction site. After stirring with adequate amount of water, it can be used directly.
There are usually two kinds of dry mortars- normal type and purposed type-Normal type includes masonry mortar, plastering mortar and ground mortar, Special purposed ones like tile adhesive, interface dry powder, insulating mortar, self-leveling, water-proof mortar, repair mortar, wall putty and tile grout,etc.
Comparing with traditional made-on- site mortar, it has many advantages like stable quality, complete kinds, high work efficiency, good work performance and easy to operate ,etc.
- Dry-mix mortar can be transported simple container, stirred automatically, pumped and applied by machine, thus making work efficiency to 500-600%. Stirring and applying by machine also ensures mortar can be processed and used correctly, avoiding water added too less or much, or other potential mistakes during formulation or inexperienced workers. It can make quality stable and durability longer.
- Dry-mix mortar helps the improvement of industrial structure, modernizes the construction industry, reduces cement waste and project cost.
- Dry-mix mortar as a thermal insulation and environmental friendly material, can contribute to energy saving and emission reduction, which should be promoted on large scale.
- Dry-mixed mortar brings significant economic benefits, while ensuring quality, the thickness of dry mixed mortar can be reduced, saving materials, and reducing material loss during transportation and use. The use of dry mixed mortar can improve work efficiency by 5-6 times. In the current situation of a significant increase in labor prices, the superiority of reducing personnel and increasing efficiency is particularly important.
- Dry mixed mortar meets environmental requirements: The use of dry mixed mortar reduces dust pollution on the construction site, improves labor protection, and is beneficial to environmental protection.
- The variety of dry mixed mortar products is complete, which can meet different engineering requirements.
In summary, dry-mixed mortar has been widely used in construction due to its advantages of stable quality, convenient use, energy conservation and emission reduction, significant economic benefits, environmental protection, and diversified product types.
