Abstract

The invention discloses a cement slurry testing device, which is used for testing the permeability of the cement slurry. The equipment comprises a first shell and a second shell, and the second shell is detachably and fixedly connected with the first shell. A cylinder is formed, and the inner wall of the first housing and the inner wall of the second housing are enclosed to form an accommodating cavity inside the cylinder, and the accommodating cavity has an opening for injecting the test material. The invention also discloses a cement slurry testing method. The invention can adapt to the characteristics of the substrate to be repaired and strengthened, and quickly and effectively and accurately quantitatively characterize the permeability of the slurry.

Description

technical field [0001] The invention relates to the technical field of material testing, in particular to a cement slurry testing method and cement slurry testing equipment. Background technique [0002] In construction occasions such as crack repair and ground reinforcement, it is usually necessary to use permeable cement slurry. The permeable cement slurry can penetrate into the voids of the matrix and then solidify to achieve the purpose of repair or reinforcement. [0003] However, at present, the viscosity of the slurry is mostly used to characterize the permeability of the slurry. However, the permeability of the slurry is also related to the characteristics of the matrix to be repaired and reinforced, such as the width of the crack and the particle size of the soil. Slurry with the same viscosity has different permeability in different matrices, so it is not intuitive and accurate to use viscosity to characterize the permeability of slurry, and cannot effectively quan...
