The invention discloses a
coal gangue baking-free
brick with mouldproof and antibacterial effects. The
coal gangue baking-free
brick is prepared from
coal gangue,
basalt powder, electrolytic
manganese residue,
hemp fiber,
chitosan,
red mud, limestone, aluminum dihydrogen
phosphate, water glass, modifier, cementing material,
boron mud and a proper amount of water. The baking-free
brick is easy to produce and low in cost. Through the synergistic effect of different materials, the prepared baking-free brick is high in strength, low in heat
conductivity coefficient, good in anti-crack effect, energy-efficient and
environmentally friendly, and meets constructional
engineering requirements and the requirement for environment protection; besides good mouldproof, antibacterial and pest killing effects, excellent performances including light weight, high strength, heat insulation, sound insulation and low water absorbability are realized; the baking-free brick has excellent high and low
temperature resistance, the problems of ordinary baking-free bricks of being poor in
crack resistance and freezing resistance are solved, and the application range of the baking-free brick is widened greatly.
