1cover block has high strength
Made by special arrangement through long-term experiment, the compression strength is up to 70MPA, and its practicability is much higher than that of other materials.
2. High durability
Using the same materials and concrete, adhesion, expansion coefficient is consistent, do not produce gap even steam curing, completely can be combined with concrete, effectively prevent air, water, sea water infiltration caused by steel corrosion and concrete loss, no mortar and plastic pad, greatly improving the security of the durability of the reinforced concrete.
