摘　　要：主要介绍了复掺技术在冬施商品混凝土中的试验及应用,提出了配合比设计思路,确定了不同混凝土等级的胶凝材料总量,对常用混凝土等级进行了负温强度试验,并在工程中应用,取得了较好的技术经济效果。This paper mainly introduces the ready mixed concrete in winter construction. The amount of cementing materials for different experiment and application of multi - mixing technology in thought of mixture proportion design is proposed. The total strength grade is determined. The compressive strength used concrete strength grade were tested and applied in the engineering at negative temperature. A of commonly result is acceptable technologically and economically.
