摘　　要：通过正交试验,研究了用水量、砂率、沸石掺量、矿渣掺量、沸石比表面积5因素对矿渣-沸石混凝土工作性能、抗压强度和氯离子渗透性的影响。综合考虑各因素对三指标的影响,得出制备C40混凝土的适宜配合比为:水量160kg/m3,砂率40%,矿渣掺量30%,沸石掺量15%,沸石比表面积530m2/kg。通过扫描电子显微镜SEM对混凝土微观结构和水化产物形貌进行了简要分析。By using the orthogonal test, the influences of the water consumption, sand ratio, dosage of zeolite and slag and specific surface area of zeolite on the workability, compressive strength and chloride ion penetration of the slag-zeolite concrete are studied. The results show that the suitable mix proportion of C40 slag-zeolite concrete is that： the water consumption is 160kg/m3, the sand ratio is 40%, the dosage of slag is 30%, the dosage of zeolite is 15%, and the specific surface area of zeolite is 530 m2/kg. The microstructure of concrete and morphology of hydration products are analyzed by scanning electron microscopy.
