Abstract

The present invention relates to air-adding concrete. The air-adding concrete has the components of the respective weight percent of 50% to 60% of quartz sand, 5% to 20% of cement, 20 to 40% of lime, 8% of gypsum, 0.05 to 0.12% of aluminium powder and water as the rest. The manufacturing method of the air-adding concrete of the present invention comprises the following steps: 1, the quartz sand is firstly ground and then manufactured into slurry; 2, the components are proportioned according to the weight percent; 3, the components are poured, evaporated and cut after maintenance; 4, the components are manufactured into block finished products and packed after being maintained in a steam pressurizing mode in a steam pressurizing kettle. The present invention has the advantages of low manufacture cost, good quality, light weight, easy construction, convenient electric pipe and water pipe burying, good fireproof performance, favorable sound isolation effect and heat preservation effect, quartz sand waste material is fully utilized to replace the principal raw material of flyash and sandstone of the existing blocks, the quartz sand is changed from wastes into valuables, and the present invention does not flake, bulge or crack after being plastered.

Description

A kind of aerated concrete and making method of adding

Technical field

The present invention relates to a kind of material of construction, mainly is a kind of aerated concrete and making method of adding, between the internal partition wall, market that is used for skeleton construction divides and the non-load bearing wall of all kinds of buildingss.

Background technology

At present in the material of construction, because that conventional clay is ruined the field is serious, country has limited use, particularly non-load bearing wall and has banned use of clay brick.And all there is certain shortcoming in some main productss of using at present: the GRC light partition board can shrink and cause the straight flange cracking; Also can ftracture after aerated blocks whitewashes, even can sheet flake and come off; Not only price is expensive but also sound insulation is also bad for light steel keel gypsum board; The woven wire sandwich panel, it is big to whitewash difficulty, and the water power pipe is buried underground and is difficult for construction, and is unhygienic; The cinder holllow building block can not bury fulgurite, water pipe underground, and raw material resources is limited.

Summary of the invention

The objective of the invention is in order to overcome above-mentioned deficiency, and provide a kind of quartz sand that makes to turn waste into wealth, utilize quartz sand to add aerated concrete and making method for main raw material.

The technical solution adopted for the present invention to solve the technical problems.This aerated concrete that adds, the weight percent proportioning of its composition is respectively: quartz sand 50%, cement 15%, lime 25%, gypsum 8%, aluminium powder 8/10000ths, all the other are water.

This making method that adds aerated concrete comprises the steps:

1), quartz sand is ground back slurrying earlier;

2), by following weight percent proportioning: quartz sand 50%, cement 15%, lime 25%, gypsum 8%, aluminium powder 8/10000ths, all the other are water;

3), a cast and a vapour are handled the back cutting of resting;

4), in autoclave, behind the steam press maintenance, make the building block finished product packing.

Advantage of the present invention is: dioxide-containing silica is at the title quartzite more than 98.5%, quartzite is called quartz sand after fragmentation, quartz has higher fire performance, make full use of the quartz sand waste material, the main raw material flyash and the sandstone that replace existing building block, quartz sand is turned waste into wealth, and not only low cost of manufacture, and quality is good.Product of the present invention has following characteristic: in light weight, construction easily buries fulgurite, water pipe conveniently; Fire resistance is good, and soundproof effect is good, does not flake after whitewashing, and does not play drum, does not ftracture; Heat insulation effect is arranged.

Embodiment:

Below in conjunction with embodiment the present invention is further described.

Embodiment 1: this aerated concrete sheet material that adds, and the weight percent proportioning of its composition is respectively: quartz sand 50%, cement 15%, lime 25%, gypsum 8%, aluminium powder 8/10000ths, all the other are water.

The making method that adds the aerated concrete building block of the present invention, it comprises the steps:

1), quartz sand is ground back slurrying earlier;

2), by following weight percent proportioning: quartz sand 50%,, cement 15%, lime 25%, gypsum 8%, aluminium powder 8/10000ths, all the other are water.

3), organizing mould and reinforced mesh handles;

4), a cast and a vapour are handled (being naturally cooling) back cutting of resting;

5), steam press maintenance was made the sheet material finished product packing after tens hours in autoclave.
