Abstract

The invention discloses a colored carbonized hardening material and its preparation method and application. The colored carbonized hardening material is composed of the following raw materials in parts by weight: 83-88 parts of carbonized gelling material, 0.5-2 parts of pigment, and 0.4-1.5 parts of carbonization enhancer 10-15 parts of water. The colored carbonized hardening material provided by the invention has rich colors, high compressive strength, good wear resistance, long service life, and can be used as colored ceramic tiles; the preparation method of the colored carbonized hardening material has simple preparation process, high controllability and low cost , At the same time, it can solidify carbon dioxide, which is in line with the concept of green energy saving and emission reduction in today's society.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a colored carbonized hardening material and its preparation method and application. Background technique [0002] The cement industry is the main part of the construction industry. Since the original Portland cement was invented, it has become the most widely used building material in the world due to its good mechanical properties and construction performance. However, the cement industry is globally recognized as a large carbon dioxide emitter, and its carbon dioxide emissions mainly come from the combustion of fossil fuels and the decomposition of calcium carbonate. 2 A large amount of emissions, the global temperature is gradually rising, leading to the greenhouse effect, which runs counter to today's sustainable development. CO 2 The use of carbonization has attracted more and more attention from scholars, and carbonization has emerged as the times require. [...
