摘要

磁处理可以改善水泥浆的性能。介绍了试验仪器、试剂和试验方法。通过测定磁化前后水泥颗粒 ξ电位可知,在最佳磁感应强度 0.2 3T下,磁化后 ξ电位绝对值提高 2.5mV。对所选用的 6种常用的水泥添加剂进行了试验,对不同的添加剂,磁处理后 ξ电位绝对值有不同程度的提高,提高值约在 5~4 0mV之间,为从理论上解释磁处理改善水泥浆性能提供了依据。

Abstract

It is known that the method of magnetic treatment can be used to improve the performance of cement slurry. The test instruments, reagents and experimenting methods are presented. By measuring the zeta potential between cement granules before and after magnetization, it shows that under the premium magnetic induction strength of 0.23T, the absolute value of zeta potential after magnetization increased by 2.5mV. Six conventional cement additives are also tested, and the increases of absolute value of zeta potential range from 5~40mV. The test provides the theoretical evidence for interpreting why magnetic treatment can improve the performance of cement slurry.
