| 1. High water reduction rate: it can make the water reduction rate of mortar reach more than 20%, and greatly improve the fluidity of mortar under the condition of the same water addition of mortar. 2. Early strength and high strength: it can improve the early strength, ultimate strength and ultimate strength of mortar. It is the best choice for various applications requiring rapid curing. 3. High durability: reduce the water binder ratio of mortar, improve durability, reduce shrinkage and creep deformation, and reduce shrinkage cracking in the later stage of mortar curing. 4. Green environmental protection products: the production process will not produce pollution to the natural environment and meet the ISO14000 international standard for environmental protection management. |
| It is a polycarboxylic acid reinforced water reducer specially used for dry powder mortar. This product has good adaptability with cement and other admixtures. It is widely used in cement-based dry powder materials such as cement non shrinkage grouting / mechanical grouting material, repair mortar, cement base floor mortar, waterproof mortar, pointing agent and polystyrene particle thermal insulation mortar. It can improve the fluidity of mortar, improve the early and late strength of mortar It is of great help to reduce the shrinkage and cracking of mortar in the later stage of curing. In addition, the product can also be used in gypsum based dry powder materials, refractories and ceramic products. |
