Abstract

The invention discloses a brown concrete block and a preparation method thereof. The concrete block comprises white cement, iron tailings, umber, waste paper pulp residues, calcium aluminum silicate, ethoxyl methyl cellulose ether, basalt fibers, ethylene-vinyl acetate copolymer, micalex, a naphthalene-based superplasticizer, Mn1.5Crl.5O4 ceramic pigment, sodium thiosulfate, red mud, and a composite additive. The various concrete block raw materials are creatively and organically combined, and the preparation process is optimized, so as to obtain the brown concrete block with the characteristics of good compressive properties, high fireproofness and thermal insulation, healthy and environment-friendly effects, small heat-conducting performance coefficient, light weight, low water absorption, and bright color.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a brown 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 object of the pr...
