Abstract

The invention relates to a cement-slag-sand type aerated concrete building block and belongs to the technical field of manufacturing of concrete building blocks. The cement-slag-sand type aerated concrete building block is mainly composed of the following components: 18-20% of cement, 30-32% of slag, 48-52% of sand, 0.07-0.08% of aluminium powder, 4kg/m<3> of soda ash, 0.4kg/m<3> of borax and 0.6L/m<3> of soluble oil, wherein the ratio of water to material is 0.6-0.7. The cement-slag-sand type aerated concrete building block has the beneficial effects that technology is simple, matching is accurate, a manufactured brick is light in unit weight, good in thermal insulation property, sound insulation property, anti-penetrability performance and fire resistance, high in strength and environmental friendly, and resource is saved.

Description

A kind of cement-slag-sand mold air-entrained concrete building block
Technical field:
The present invention relates to a kind of cement-slag-sand mold air-entrained concrete building block, belong to building block manufacturing technology field.
Background technology:
Autoclave aerated concrete building block is to add aluminium powder to make air entraining agent in the batching with calcareous material (as cement, lime) and siliceous material (as sand, flyash, slag), through adding water stirring, casting, the expansion of getting angry, precuring cutting, then the porous silicate building block forming through autoclave curing.
The unit weight of autoclave aerated concrete building block is 1/3rd of clay brick, and heat-insulating property is 3-4 times of clay brick, and sound-proofing properties is 2 times of clay brick, and anti-permeability performance is the more than a times of clay brick, and fire performance is 6-8 times of Steel Concrete.The masonry strength of building block is about 80% of building block self intensity.
The construction property of autoclave aerated concrete building block is also very good, it not only can produce all size in factory, can also as timber, saw, digs, bores, follow closely, again because its volume ratio is larger, therefore speed of application is also very fast, can be used as the packing material of various buildings.
Summary of the invention:
Technical problem to be solved by this invention is to overcome the defect of prior art, and a kind of cement-slag-sand mold air-entrained concrete building block is provided.
Technical problem to be solved by this invention realizes by the following technical solutions.
Cement-slag-sand mold air-entrained concrete building block, is characterized in that: mainly following composition, consist of:
The specific requirement of described sand is: SiO2 total content >=70%, wherein quartz content >=40%; K2O+Na2O≤5%; Humus content≤3%; Carbonate content≤10%; Clay content≤8%; Cl-content≤0.02%, loss on ignition≤5%
The specific requirement of described slag is: 1. water extraction quality is good, and particle is loose, even, without scum and grit; 2. CaO >=40%, Al2O3=9%~16%, SO3=0.8%~1.6%, muriate≤0.02%; 3. mass ratio >=1 of CaO/SiO2.
Described soluble oil is specially: soluble oil is by oleic acid, trolamine and water, coordinates and forms at normal temperatures in 1:3:36 ratio.
The content of the CaSO42H2O of described gypsum should be not less than 80%, P2O5≤0.8%.
Beneficial effect of the present invention is: technique is simple, and proportioning is accurate, and the fragment of brick unit weight of making is light, good heat insulating, and the masonry strength of sound-proofing properties, anti-permeability performance, fire performance and building block is all better, and environmental protection economizes on resources.
