| 摘 要： | 研究了以矿渣、石膏、石灰为主要原料的矿渣胶凝材料在蒸养下抗压强度的影响因素,并通过正交实验方法对原料的配合比、蒸养条件等进行了优选。结果表明:在蒸养温度80℃时,掺入8%的石膏、14%的石灰复合激发剂能较好激发矿渣的活性,胶凝材料28d的抗压强度达到85MPa。

| Abstract: | The influencing factors of compressive strength of the alkali slag cementitious material prepared by slag,gypsum and quicklime under steam curing were investigated.The ratio of these feed materials and the condition of steam curing were optimized by the method of orthogonal design.The test results showed that under the conditions of the steam curing temperature is 80℃,the dosage of gypsum is 8%,the dosage of quicklime is 14%,the activation of slags can effective accomplished,and 28day′s compressive strength of the cementitious material is above 85 MPa. |
