Thixotropic cement slurry system types and evaluation methods

Abstract

: Thixotropy is one of the important contents of the rheology for dispersed systems. Thixotropy is widely used in engineering cement slurry, and the thixotropy of substances in actual engineering is often used as an auxiliary means and method of engineering technology. The concept and mechanism of thixotropy are briefly introduced. The thixotropic cement slurry system is divided into inorganic and organic types, and the shortcomings of various types of thixotropic cement slurry are pointed out. The evaluation methods of the thixotropic ring method, static shear force method, hysteresis ring total energy method, thixotropic index method, thin blade horizontal cutting method, step method, hysteresis loop method, and thixotropic coefficient method is introduced. Finally, future research on thixotropy has prospected.
