摘　　要：研究了矿渣细化后对相同比表面积普通水泥的力学性能影响以及硬化浆体结构的形成、发展。研究结果表明,由于矿渣水化速率的提高,导致在矿渣参与水化后的低钙条件下形成粗大柱状的钙矾石,破坏已硬化的水泥浆体结构,并由此影响水泥力学性能的正常发展。The effect of addition of ultra fine GGBS on physical properties of ordinary Portland cement with same surface specific area was studied,and the formation and development of cement hardened paste was also studied.The results showed that due to the rate of hydration of GGBS was accelerated,the coarse columnar ettringite was formed under the low calcium condition.The structure of hardened cement paste was damaged by coarse columnar ettringite,and affected physical properties of cement.
