硅酸盐类水泥的磁性试验研究

Trial study on magnetism of Potland cement

从水泥的磁特性入手研究混凝土的磁特性,运用铁磁学的基本理论和试验方法对硅酸盐类水泥的磁特性进行试验研究。从实验所得的磁滞回线可知,普通水泥和复合水泥在外加高场作用下具有一定铁磁特性,而白色水泥则表现为弱磁性。通过量化分析,给出了鉴定水泥磁性的指标值为2.0Gs。

Start with cement magnetism,concrete's magnetism is studied.By basic theory and experiment method of magnetics,Pot-land cement's magnetism is studied.It can be known by the hysteresis curve gained by experiment result that Potland cement and composite cement have some iron-magnetism characteristics under function of added magnetic field,while the white cement shows weak magnetism.It has been given that the index value is2.0Gs when indentify cement magnetism on base of quantitative analysis of the characteristics.
