摘要
本文通过水泥基复合材料水泥、膨胀剂、粉煤灰、引气剂、高效减水剂中SO3与Al2 O3含量对钙矾石及混凝土膨胀性能的影响进行了研究 ,指出了SO3与Al2 O3及其比值对膨胀性能影响的重要性。试图使人们在使用补偿收缩混凝土前事先确定膨胀量 ,再根据膨胀量去确定水泥基复合材料中的SO3与Al2 O3含量 。
By studying the influence of SO 3 and Al 2O 3 in cement group complex materials,which include cement,expansion agent,fly ash,airenteraing,super plasticizer water reducer,on ettringite and concrete expansion property,it points out the importance of the influence of SO 3,Al 2O 3 and their ratios on expansion property.It intends to make people determine the expansion valumn before using concrete of compensate shrink,then determine SO 3 and Al 2O 3 in cement group materials according to the expansion valumn,consequently it obtains the conversion from certain property to ration.
