減少による経済性に優れた製品を得ることが出来る。The properties of the Hydraulic Cement 1 blend naturally depend on the quality of the raw materials used, but it can also maintain properties that are useful in the second industry depending on the blending conditions. That is, it is well known that one of the most important mixing conditions for obtaining a satisfactory hydraulic cement 1-mixture is to knead the raw materials while minimizing the unit amount of water as much as possible. As a result, it is possible to obtain a product with high strength and less cracking, and also with excellent economic efficiency due to the reduction in the amount of cement per unit.
