Improvement of Setting Property of Magnesia Phosphate Cement by Recycling Boron Mud

Abstract:

Boron mud has problems of disposal and health hazards when discharged directly to the environment, so the problem of boron mud needs to be resolved as soon as possible. Although many kinds of treatments about boron mud's problems had been tried, the pollution of boron mud also exists. While magnesia phosphate cement has many excellent characters, so it has a fine future in engineering projects, yet its application scope is limited greatly by the rapid rate of hydration reaction. This work based on the systemic researches of hydration mechanism of magnesia phosphate cement, then proposed a new method of using boron mud to produce magnesia phosphate cement, and the produced cement has an enough setting time. So this way can not only improve the setting property of magnesia phosphate cement but also help to the reclamation of boron mud.
