普通混凝土配合比设计及试配

The Design and Trial-Mixing of Ordinary Concrete Mixing Proportion in Ready-Mixed Concrete Mixing Station

针对预拌混凝土企业确定混凝土配比时"重设计、轻试配"的现状,结合配合比设计的条件要素,从混凝土配合比设计、试配、调整三个方面,系统阐述预拌混凝土配合比设计的全过程,突出强调了试配的重要性,进一步明确预拌混凝土配合比设计是在经验、理论指导下的实践性过程。

In the light of the situation in which the ready-mixed concrete plants ＂emphasise design and belittle trial-mixing＂ in determining the mixing proportion, the present essay systematically discusses the whole process of the design of the mixing proportion of ready-mixed concrete from the three aspects of design, trial-mixing and adjustment by incorporating the elements in the design of mixing proportion. The essay emphasizes the importance of trial-mixing and makes it clear that the design of the mixing proportion of ready-mixed concrete is a practical process under the guidance of experience and theory.
