The cement to concrete ratio must be suitable to meet the customer's requirements, which is commonly known as slump. If you want to have a small slump, the size distribution of cement is very important. If the size of cement is unreasonable, the demand for cement may become larger, the cost of the enterprise is bound to increase, and the speed of hydration will become faster, cement and polycarboxylate superplasticizer will be more unsuitable. The particle size of cement is also related to the grinding of the mill, and there may be excessive grinding of the mill.
If the material mixed with cement is strong in water absorption, and the adaptability of polycarboxylate superplasticizer is also poor, which affects the adaptability of cement and water reducer.
As for how to solve the problem, first of all, the raw material ratio should be calculated, the mixing amount of the material should also be adjusted, and then the machine should be adjusted to a good state when grinding.
