Concrete sanding The original of Because:
one Water cement ratio. cement mortar When configuring, the water cement ratio is too large, resulting in too thick cement mortar, which leads to Cement floor It is easy to sand. Cement floor sanding repair agent
two The calendering time is improper. （ one ）Too early. At the beginning of cement hydration, calendering will cause incomplete gel and too much water Cement table The surface appears water gloss, so the strength and abrasion resistance of the surface cement mortar are not good. （ two ）Too late. If the cement mortar has set and hardened during calendering, the difficulty of calendering will increase, and improper operation will damage the hardened surface, which will greatly reduce the strength and anti-wear ability of the surface sand.
three Improper maintenance. Cement mortar floor generally needs curing seven Days. This period includes initial setting, final setting, hardening and hydration of cement after mixing with water. Although you can walk when it dries the next day, the beginning of cement hardening does not mean the end of hydration. Hydration will also penetrate into the cement particles and continuously strengthen the strength of cement mortar floor from the inside. If the curing time is not enough, the hydration of cement will be affected, thus affecting the strength.
If cement mortar construction twenty-four Water curing within hours may cause hollowing, which will adversely affect the quality of the cement floor.
Concrete sand control agent
How to govern Concrete sanding ？
You can use the concrete Seal curing agent!
What is concrete sealing curing agent?
Compounds infiltrated into the concrete and semi hydrated cement, free calcium, silicon oxide and other substances contained in the set concrete undergo a series of complex chemical reactions to produce hard substances. These compounds will eventually improve the compactness of the concrete surface, thus improving the strength, hardness, wear resistance, impermeability and other indicators of the concrete surface, So as to solve the problem of concrete sanding.
