摘要
Substantial research results show that the magnetised water can make the cement hydration reaction more completely, so the properties of magnetised water are studied in the thesis. The research starts with the chemical properties of magnetised water such as the conductivity, viscosity, pH value. On the basis of the study of magnetised water by the predecessors, a test about the application of magnetised water on sprayed concrete has been taken based on the selected magnetised parameters. The magnetised water which is used to mix concrete can improve the performance of concrete. This paper presents the effect of magnetised water on performance of sprayed concrete in laboratory. The results indicate that the early strength of concrete mixed with magnetised water has been obviously improved. © W. S. Maney & Son Ltd 2015.
