Abstract

The invention discloses a special building foam brick. The special building foam brick comprises, by weight, 20-30 parts of building garbage, 7-13 parts of calcined kaolin, 10-20 parts of diatomaceousearth, 5-10 parts of granite, 15-25 parts of fly ash, 4-9 parts of floating beads, 6-14 parts of epoxy resin, 20-30 parts of cement, 5-12 parts of expanded perlite, 6-11 parts of talc powder, 2-4 parts of calcium stearate, 4-8 parts of modified bagasse, 2-5 parts of lignin, 2-4 parts of sodium lignosulfonate, 1-3 parts of sodium dodecyl sulfate, 2-3 parts of water reducing agents and 4-8 parts ofChinese herbal medicine mixtures. The special building foam brick has the advantages that raw materials for the special building foam brick and ratios of the raw materials are controlled, accordingly, the prepared special building foam brick is low in heat conductivity coefficient and density and high in compressive strength and flexural strength, and has a nerve soothing function, aroma furthercan be released by the special building foam brick, and the like.

Description

technical field [0001] The invention belongs to the technical field of foam bricks, and in particular relates to a special foam brick for construction and a preparation method thereof. Background technique [0002] Foam bricks have good compressive properties: the compressive strength is greater than 0.5Mpa, the highest strength can reach more than 10.5Mpa, no cracking, long service life, foam bricks are also made of different raw materials. Foamed cement bricks are made by mixing and coagulating small foam particles with cement. They have high-quality properties of light weight, heat preservation, sound insulation and fire prevention, and the cost is greatly reduced due to the use of small diameters. They are ideal for non-load-bearing walls. Autoclaved foam concrete bricks are mainly made of cement, slag powder, and river sand as raw materials. After mixing, they are foamed with pressure air and forced to mix air into the mixed slurry. The concrete with micro-bubble struct...
