高性能膨胀剂(CMA)的研究与生产

Research and production of high performance expansion admixture(CMA)

综合目前国内膨胀剂领域的发展方向和借鉴以往研究成果,采用CaO(钙质熟料)、钙矾石、MgO三个膨胀源的相互作用,三者膨胀适当组合,取长补短,以获得更适宜的膨胀量和膨胀发挥,使膨胀曲线更趋合理。研究了不同掺量不同活性钙质熟料对CMA膨胀剂性能的影响,提出了制备钙质熟料的理化指标,并将CMA与传统膨胀剂的性能进行了对比。

To synthesize the development direction of civil expansion admixture field presently and refer to the performance of past, utilizing the reciprocal action and suitable combination of three expansion fountain namely CaO(calcareous clinker), AFt and MgO to get better expansivity, to make expansion curve more reasonable. The influence of different amount of addition and reactivity of calcareous clinker on the CMA expansion admixture's performance was studied, and the index of furnishing calcareous clinker was put forward, moreover, the performance of CMA and traditional expansion admixture was paralleled.
