Heat-preservation sound-proof low-density foamed concrete

Abstract

The invention discloses heat-preservation sound-proof low-density foamed concrete. The heat-preservation sound-proof low-density foamed concrete is characterized by being prepared from, by weight, 40-100 parts of cement, 5-40 parts of carbide slags, 5-40 parts of active powder, 1-20 parts of foaming agents, 0.1-8 parts of foam stabilizers, 0-8 parts of water reducing agents, 0-8 parts of coagulation accelerator, 0-25 parts of waterproof agents, 0.1-5 parts of anti-cracking agents and 25-150 parts of water, and the foamed concrete is prepared from the materials through mixing, foam molding and maintenance. The heat-preservation sound-proof low-density foamed concrete has the advantages of being low in dry density, low in heat conductivity coefficient, high in strength, wide in raw material source, low in cost, simple in preparation technology, convenient to prefabricate in factories or pour on site and the like; the heat-preservation sound-proof low-density foamed concrete is suitable for building exterior wall heat-preservation engineering, roof heat-preservation engineering, floor heating heat-preservation engineering, composite heat-preservation wall engineering, backfilling engineering, retaining wall slab engineering and the like.

Description

technical field [0001] The invention relates to a chemical foaming foam concrete. As a light heat-insulating and sound-insulating material, the present invention is suitable for building exterior wall insulation engineering, roof insulation engineering, floor heating engineering, composite wall insulation engineering, backfill engineering, retaining wall panel engineering, etc., and is especially suitable for building exterior wall insulation systems, Roof insulation system, floor heating engineering and composite wall insulation engineering, etc. Background technique [0002] At present, there are more than 10 types of external thermal insulation materials for building external walls in my country, such as expanded polystyrene (EPS) boards and extruded polystyrene (XPS) boards, among which EPS board thin plaster external wall external thermal insulation systems are widely used throughout the country. technology, accounting for almost more than 90% of energy-saving buildings...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to solve the deficiencies of existing physical foaming to prepare foamed concrete and to realize the recycling of calcium carbide slag, etc., to provide a kind of raw material with wide sources, low price, simple preparation process, and convenient for factory prefabrication and on-site pouring. Method for preparing heat-insulating and sound-insulating low-density concrete

The foam concrete of the present invention has low dry density (50-350kg / m 3 ), high strength (0.06-1.6MPa), low thermal conductivity (0.03-0.08W / m K), flame retardant, wide source of raw materials, low price, simple preparation process, high cost performance, etc., which solves the current thermal conductivity of foamed concrete The high coefficient makes it impossible to replace the organic insulation boards for interior and exterior walls. At the same time, it also improves the added value of the utilization of waste resources of calcium carbide slag, turning waste into treasure and turning harm into profit. It can completely replace the current organic insulation materials for exterior wall insulation, Roof insulation, floor heating engineering and composite wall insulation engineering and other fields
