摘要:
为了探寻矿粉细度及掺入量对水泥和混凝土性能的影响，通过试验测试方法，分析了矿粉和水泥的基本性质，研究了超细矿粉和普通矿粉的掺量对水泥基材料标准稠度、凝结时间、流动度和力学性能的影响.结果表明：普通矿粉使水泥净浆标准稠度需水量下降，而超细矿粉则增加标准稠度需水量，两种矿粉都使水泥净浆凝结时间略微延长.普通矿粉可以改善水泥净浆的流动度，超细矿粉的加入则降低了水泥净浆的流动度.普通矿粉和超细矿粉降低水泥净浆早期（7 d）抗压强度，提高后期（28 d）抗压强度，掺10%～50%的普通矿粉的水泥净浆28 d抗压强度提高2.9%～9.7%，掺入超细矿粉28 d抗压强度提高3.9%～20.1%，普通矿粉和超细矿粉的最佳掺量为10%～30%；两种矿粉替代10%～50%水泥所配制的混凝土的强度得到了明显的提高.
Abstract:
To explore the influence of fineness and dosage of slag on cement and concrete, the basic properties of slag and cement were analyzed, such as the normal consistency, setting time, fluidity and mechanical properties of cement and concrete by adding ultrafine slag and ordinary slag. The results show that the water requirement for normal consistency of cement paste decreases by using ordinary slag, increasing by using ordinary slag; both of them slightly postpone the setting time of cement paste; ordinary slag improves the fluidity of cement paste, while the ultrafine slag reduces the fluidity of cement paste; the early(7 d) compressive strength of cement paste decreases and the later(28 d) compressive strength of cement paste increases when ordinary slag and ultrafine slag are added; the 28 d compressive strength of cement paste added 10%\|50% ordinary slag is improved by 2.9%\|9.7%,while it is improved by 3.9%\|20.1% after adding ultrafine slag;the optimal replaceable content of ordinary slag and ultrafine slag is 10%\|30%,and the compressive strength of concrete is enhanced greatly when the two kinds of slag are added to 10%\|50%,respectively.
