On the premise of the quality of concrete, reducing the dosage of cement is to reduce unit cost of concrete price, which is also one of the important measures to prevent concrete cracking. In the commercial concrete with fly ash, not only can reduce the hydration heat, but also can reduce the cost. According to the market, prices for cement commonly 1/3 of fly ash. If excessive dosage of fly ash, the configuration of concrete strength can not meet the design strength. If the amount of fly ash replacing cement is too small, it will be short of cost reduction purpose, does not favor the concrete crack control at the same time.
