Abstract As a traditional industry, the cement industry is a large resource and energy consumer and a large carbon emitter. This is inconsistent with the “construction of a resource-saving and environment-friendly society” advocated by China. In recent years, people have gradually paid attention to the use of cement clinker and other auxiliary mineral admixtures are used in concrete instead of cement. Through a large number of experiments, this work has proved that the best specific surface areas of cement clinker and superfine composite admixture are 370 m2/kg and 650 m2/kg, respectively; on this basis, the research the effect of different proportions of cement clinker, superfine composite admixture, fly ash, on the performance of cement mortar and the effect on the performance of C30 concrete. The clinker and concrete are tested and analyzed by chemical analysis, XRD and SEM, etc. The result shows that the most suitable ratio of C30 concrete is water 175 kg/m3, conch cement clinker 130 kg/m3, stone 1 050 kg/m3, sand 810 kg/m3, superfine composite admixture 110 kg/m3, fly ash 80 kg/m3, ore the powder is 40 kg/m3, the water reducing agent is 8.9 kg/m3, and the performance of the prepared C30 concrete is good, and the compressive strength meets the requirements.
