1. The strength of the block is made by the special formula through the long-term test. Finally, its compression strength reaches 70MPA, and its practicability is much higher than that of other materials.
2. Block durable high materials used in the same as the concrete performance, strong adhesion, consistent expansion coefficient, and even steam curing does not produce clearance, can merge with concrete as a whole, to prevent air, rain, water and other causes of reinforcement corrosion and concrete falls off, no mortar and the plastic pad of sorrows, greatly improving the security of the durability of the reinforced concrete.
3. The high precision and high strength concrete block of the protective layer is accurate, and has a protective layer of high steel seal, which is completely different from the random nature of the mortar pad.
4. After the pad is removed, the contact surface with no color difference pad and the template is of high stability, and no "patch" is consistent with the "patch" after stripping, which is especially suitable for the concrete structure of clear water.
The total alkalinity of the pad is low in environmental protection materials and the total alkalinity is low.
