1, the technical performance of cement must meet the requirements of the existing national standards, in particular, should maintain product homogeneity and stability, chemical composition, fineness, age intensity grade, setting time, standard consistency water demand and other indicators can not have Large fluctuations, especially the intensity value can not be ups and downs.
2, Concrete batch plant in the preparation of concrete water to be small, good mobility, and admixtures have a better adaptability; cement grinding not only to control the fineness and to rational control of cement particle size and particle shape.
3, concrete mixing plant varieties of cement mixed material matching mix to science, reasonable;Attaches great importance to the gypsum variety choice, should attach great importance to the control of temperature of the cement factory.
4, in the special requirements of concrete, should provide special cement, if low alkali requirements to provide low-alkali cement; have low heat requirements, the commercial concrete mixing plant to use hydration heat low cement.
