Combining meticulously, designing scientificly and making experiments completely,we develop QW series of composite high-efficiency additive,which fits the minus temperature high-performance concrete in the special environment of Qinghai-Tibet plateau.

To highly president the characteristic and economic characteristic of concrete by fully improving the characyeristic of highly effectual admixture, and combining with the reasonable adjustment of the proportion of kinds of binding materials in premixing concrete.

A new colour cement based coating is prepared by using Portland cement as the base material,adding in pigment,filler,and compound admixture,and modified by filling an emulsion.

Under these conditions,compound admixture for high content slag cement has also been made.

With the conditions of slag cementitious of low clinker, compound admixture for high content slag cement was made.

Through experiments, the content proportion for producing gypsum tailings wall materials and the optimum amount of CaO composite additives were determined in this paper.
