Embodiment Construction

[0020] Below in conjunction with specific embodiment, further illustrate the present invention.

[0021] A method for artificially preparing fragile materials, characterized in that it comprises the following steps:

[0022] Step 1, preparation of raw materials:

[0023] The raw materials used are cement, clay, and water, and the mass ratio of the cement, clay, and water is 250-400:1000:50-560;

[0024] Step 2, stir:

[0025] Put the raw materials in step 1 in a container, and stir evenly to obtain cement slurry, the plastic viscosity of which is 0.009 Pa·s.

[0026] Step three, granulation:

[0027] The cement slurry that step 2 is obtained is kneaded into the particle that diameter is 20mm;

[0028] Step four, pressing:

[0029] The granules prepared in step 3 are put into a mold with a circular groove, and pressed to obtain spherical granules with a size of 20mm;

[0030] Step five, shaping:

[0031] The spherical granules prepared in step 4 were shaped for 24 hours,...

Abstract

The invention relates to an artificial preparation method of a fragile material, which is characterized in that the method comprises the following steps: preparing raw materials of cement, clay, and water, wherein the mass ratio of the cement, clay and water is 250-400:1000:50-560; then stirring, compacting and molding the raw materials to obtain the final product.

Description

technical field [0001] The patent of the present invention relates to a method for artificially preparing fragile materials. Background technique [0002] Fragile materials were prepared to better study the crushing of granular materials. So far, the crushing of materials is mainly carried out for natural materials, such as sand and rockfill materials. However, due to the complex properties of natural material particles, such as irregular particle shape, different joints and fissures inside the material, and different particle mineral compositions, many factors that affect the mechanical properties of materials are coupled together, and it is difficult to study the influence of a single factor. . Therefore, the artificial preparation of fragile materials has become a new method. The predecessors have also proposed some methods for the preparation of fragile materials, such as using glass beads, gypsum rods, quartz particles, cemented sand and other materials to simulate na...
