Early strength crack resistant material KzM SR (Q)

Early strength anti cracking material is a fast setting and early strength cement-based quick repair, cushion reinforcement and leveling material that can compensate for cement shrinkage. It is particularly suitable for filling and repairing after slotting in new and old building floors, filling and repairing after removing the original filling layer or decorative layer of damaged floors, filling and repairing after crack expansion before waterproofing construction on floors, reinforcing non structural beams and columns, and repairing non load bearing damaged floors. The crack resistance leveling of seamless grinding stone foundation layer can also be used for grouting construction of small volume concrete gap holes, equipment foundations, etc. Its plastic state and hardening after mixing with water can produce controlled micro expansion performance, and an appropriate amount of crushed stone can be added to make early strength crack resistant concrete.
