Abstract

The invention discloses a red concrete block and a preparation method thereof. The block comprises white cement, iron tailings, fly ash, gravel, calcium aluminum silicate, hydroxyethyl methyl cellulose ether, basalt fibers, redispersible latex powder, mineral wool slag, a naphthalene-based superplasticizer, chromium-yttrium-aluminum red ceramic, sodium thiosulfate, red mud and a composite additive. Various raw materials of the concrete block are creatively and organically combined, and the red concrete block with good compression resistance, fire-proofing, heat insulation, health care, environmental protection, small heat-conducting coefficient, light weight, low water absorption and bright color is obtained with an optimized preparation process.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a red concrete block and a preparation method thereof. Background technique [0002] With the rapid development of my country's building ceramics industry, my country's demand for building ceramic materials is becoming more and more vigorous, and at the same time, the requirements for various performances of building materials are getting higher and higher. It is more and more common to use concrete decorative blocks for the walls of residential quarters, roofs and floors of buildings, square walls, and protective slope embankments. Especially the research of colored blocks is a direction of research now. However, the current concrete blocks generally use ordinary pigments, and their self-weight and thermal insulation properties cannot meet the needs of buildings for building energy conservation. Contents of the invention [0003] The purpose of the pre...
