Welcome to your call. The reason concrete analysis of a cement from the sand, uneven mixing????? Uneven mixing mortar, mortar shrinkage when watering, draft varies, sand, peeling from too much water at the prone. ????? 2, improper preparation of water-cement ratio??????? (1) water-cement ratio is too small, resulting in large amount of cement, mortar, relatively dry and hard, construction difficulties, undermining the strength of the surface layer. ??????? (2) water-cement ratio is too large. In order to enhance the workability of the mix, arbitrarily increase the water-cement ratio, resulting in too little amount of cement, surface bleeding phenomenon, mortar strength decreases, the surface layer do not wear loose cement gray appear after walking surface, resulting in from sand phenomenon. ?????? 3, the raw material does not meet the requirements??????? (1) of sand particle size too small, too large mud. Sand particle size is too small, when mixing cement ratio is increased, reducing the strength; excessive sand, clay, cement content per unit volume is reduced, the impact force at the time of mixing the adhesive, reducing the strength, resulting in surface resistance Grinding reduced, resulting from sand phenomenon. ??????? (2) low-grade cement strength, stability using substandard, expired, wet, caked cement. Cement stored for too long, improper care, appeared damp, agglomeration, is still used for concrete floor construction, resulting in cement activity affected, resulting in the surface layer of mortar strength is reduced; cement stability failure, when setting and hardening deformation is too large, greatly reduces the overall strength, surface loose in the external force, the surface layer off easily, peel, formed from the sand.
