The influences of magnetized water on physical properties of concrete

摘要

The influences of magnetized water on the mechanical and optic properties of concrete, including mass density tensile strength, tensile strength, compressive strengths, deformation modulus, Poisson's ratio, cohesive force and internal friction angle as well as the infrared spectrum of absorption and fluorescence spectrum, are studied and measured in detail by different methods, involving the synthetic method of ultrasonic and rebounded techniques as well as infrared and fluorescence spectrum method, respectively. The results obtained from these investigations indicate that the mass density, tensile strength, tensile strength, compressive strengths, deformation modulus and Poisson's ratio of the concretes, but its cohesive force and internal friction angle decrease, some new peaks in the infrared spectrum occur after magnetized water is joined into the concrete relative to those of pure water. These show clearly that the magnetized water enhances the combined force among the molecules, corpuscles and components in the concrete and lifts its mass density. Thus the mechanical and optic properties of the concrete containing magnetized water. This is due to the increases of hydrophilic feature of concrete after magnetized water is joined into it.
