【摘要】 研究了粉磨对两种高钙粉煤灰物理化学性能的影响。通过混合水泥雷氏夹膨胀值、强度和自由线膨胀率等的试验测定,对两种高钙粉煤灰经粉磨后进行性能研究。结果表明,通过粉磨可以减缓甚至消除高钙粉煤灰带来的安定性问题,提高混合水泥强度,降低混合水泥自由线膨胀率。更多还原

【Abstract】 The effects of grinding on the physical and chemical properties with two types of high calcium fly ashes are studied.By testing ways of Le Chatelier’s expansion value,free expansion ratio,strength and so on,two types of high calcium fly ashes are studied.The results show that,through grinding,we could solve the soundness brought by high calcium fly ash,improve the strength of compounding cement and decrease free expansion ratio.更多还原
