Concrete tiles should GB175 provisions Portland cement and ordinary portland cement, in order to obtain high early strength with the corresponding strength grade, reducing the drying shrinkage. Early strength slag Portland cement Caizhuan lower mold, in the natural curing conditions, too much missing edge off angle will affect the appearance of the product quality; should not be used pozzolana cement, because the drying shrinkage is large, improper maintenance and construction will cause the tiles crack, affect the safety of the use of the building; the use of fly ash cement, fly ash in the case of large color brick mold box wholesale nine, drying shrinkage products than large, poorly controlled, it can make brick cracks, causing structural damage. Therefore, this standard requires compliance with GB175 Portland cement and ordinary Portland cement.
