Abstract
The invention relates to foam concrete. The foam concrete comprises, by mass, 60-90 parts of water, 120-150 parts of cement, 200-250 parts of sand, 250-300 parts of gravel, 6-10 parts of blast furnace slag, 6-10 parts of tephros, 5-8 parts of diatom powder, 10-20 parts of reinforced fibers, 20-30 parts of air entraining agent and 15-20 parts of water reducing agent. The foam concrete has the advantages of low density, light weight, heat insulation, sound insulation, seismic resistance, high strength, less proneness to cracking and low internal basicity.
Description
Technical field
The invention belongs to building material technical field is and in particular to a kind of foam concrete.
Background technology
Foam concrete is otherwise known as lightweight concrete, is that a kind of profit is useless, environmental protection, energy-conservation, cheap and have non-flame properties
Novel building energy-saving material, according to application demand by air or nitrogen, carbon dioxide, oxygen etc. by way of chemically or physically
Gas is introduced in concrete mortar, through reasonable maintenance molding, and is formed containing tiny sealed porosity in a large number, and has quite strong
The concrete product of degree, is applied to retaining wall, builds sports ground and track and field runway, sandwich structure, combined wall board, pipeline return
Fill out, lean concrete packing course, roofing side slope, the aspect such as the support of storage tank footing, have that density is little, light weight, insulation, sound insulation, anti-
The performances such as shake, but, there is the defects such as low strength, cracking in it, its performance is further improved in the application.
Content of the invention
In view of this, it is an object of the invention to passing through to change technical recipe and the parameter of foam concrete, overcome existing
The defects such as foam concrete low strength, cracking, provide a kind of foam concrete of excellent performance.
For reaching above-mentioned purpose, the present invention provides following technical scheme：
A kind of foam concrete, includes following component in parts by mass：60～90 parts of water；120～150 parts of cement；Sand 200
