摘　　要： 在采用缓凝剂的基础上,研究了水玻璃模数(n)、浓度(Css)以及矿渣替代碳酸盐矿质量分数(Ms)等对碱碳酸盐矿渣胶凝材料性能的影响,并对该体系反应产物的微观形貌和胶砂试体的孔分布进行了分析。研究结果表明,当采用适宜的n、Css和Ms 时,材料3d和2 8d的胶砂体抗压强度可分别达到5 0MPa和90MPa以上,且随龄期延长而不断增长。 The influence of the modulus (n), concentration (Css) of water glass and the replacement of ground carbonatite with ground blast-furnace slag (Ms) on the strength of alkali carbonatite-slag cementitious material (ACSCM for short) in the presence of retarder were studied in this paper. And the micro image of hydrate and micro pore distribution of this material were analyzed as well. The results showed that with appropriate n, Css and Ms, ACSCM with 3 d and 28 d compressive strength could be over 50 MPa and 90 MPa, respectively. Their strengths have been increased with the time lasting.
