Abstract

The invention discloses a method for preparing waste glass refractory high-strength concrete, which comprises the following steps: step 1, performing dry grinding on waste glass and aluminum slag to obtain waste glass particles, aluminum slag and waste glass powder; Water ethanol is used as grinding medium to carry out wet grinding treatment to waste glass powder to obtain glass powder slurry; step 3, wash and suction filter the glass powder slurry in step 2 to obtain ultrafine waste glass powder; step 4, process step 3 Superfine waste glass powder, cement, waste glass particles, aluminum slag, river sand, gravel, mixing water, water reducer and retarder are mixed and stirred to obtain refractory high-strength concrete. The invention selects solid waste as a raw material for preparation, is energy-saving and environment-friendly, and the superfine glass powder can improve the mechanical properties of concrete, and the fire-resistant performance of concrete can be improved through the reaction of silicon phase and aluminum phase.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a method for preparing refractory high-strength concrete by mixing waste glass. Background technique [0002] At the beginning of the 20th century, refractory materials were developed in the direction of high-purity, high-density and ultra-high temperature products, and amorphous refractory materials and refractory fibers that did not require firing at all and had low energy consumption appeared. With the development of new energy technology, refractory materials with comprehensive and excellent properties such as high temperature resistance, corrosion resistance, thermal shock resistance, and refractory erosion have been widely used. Under the promotion of the development of high temperature industry and technological progress, my country's refractory industry has developed rapidly. The output of refractory materials has ranked first in the world for many...
