Abstract
The invention discloses lightweight aggregate concrete including the materials in parts by weight: 1000 parts of cement, 100-180 parts of fly ash, 600-1000 parts of 1-3 mm scoria, 1200-1700 parts of 5-8 mm scoria and 18.6-19.9 parts of an additive. The additive includes the materials in parts by weight: 7.5-8.8 parts of a water reducer, 10 parts of latex, 0.1 part of a foaming agent and 1 part of a polypropylene short fiber. The lightweight aggregate concrete has the beneficial effects that a wall board developed by the scoria concrete has the advantages of light weight, thermal insulation, high strength, environmental friendliness, greenness, energy saving, waste utilization and the like, is a green building material suitable for construction industrialized application and promotion, and can be widely applied in concrete products.
Description
Technical field
The present invention relates to a kind of concrete, particularly to a kind of light aggregate concrete.
Background technology
China's scoria resource is the abundantest, and with northern area for many, quality is preferable.Scoria is a kind of merit
Can type environment-friendly materials, be by volcanic glass, the porous being of great rarity of mineral and bubble formation after volcano eruption
Shape stone material.Scoria rough surface, granule unit weight is 450kg/ cubic meter, and loose volume weight is 250kg/ cube
About meter, natural scoria porosity is 7l.8 81%, and water absorption rate is 50-60%.Its feature is quality
Gently, intensity height, acid and alkali-resistance, corrosion-resistant and pollution-free, "dead" etc., be the most natural, green,
The product of environmental protection.
At present, at building engineering field, energy-saving and emission-reduction are problems in urgent need to solve, particularly relevant mixed
In solidifying geotechnique's journey, how to gather materials on the spot, some go out of use and pollute the material of environment and how to effectively utilize
In concrete, to meet building energy conservation and to alleviate the requirement of construction weight, thoroughly reduce correlation engineering cost.
Summary of the invention
The invention aims to solve energy-saving and emission-reduction and reduction engineering cost in cement concrete engineering
Problem and a kind of light aggregate concrete of providing.
The light aggregate concrete that the present invention provides includes cement, flyash, 1-3 scoria, 5-8 fire
Fructus Crataegi and additive, the content of the most various materials is: cement 1000 parts, flyash 100-180 part,
1-3 scoria 600-1000 part, 5-8 scoria 1200-1700 part, additive 18.6-19.9 part.
Additive includes water reducer, latex, foaming agent and polypropene staple, the most various materials
Content be: water reducer 7.5-8.8 part, 10 parts of latex, foaming agent 0.1 part, polypropene staple 1 part.
Water reducer is polycarboxylate water-reducer.
Latex is styrene-acrylate emulsion.
Foaming agent is added water made by Caustic soda, osseocolla, Colophonium, nm vacuum agent, the most various materials
Content is Caustic soda 1.3 parts, 5 parts of osseocolla, Colophonium 10 parts, nm vacuum agent 0.5 part, 100 parts of water.
The ratio of mud of concrete is 0.55-0.63.
The preparing process of the present invention:
In view of scoria porous surface, the concrete grade caused by its suction for reducing cement reduces and material
Material waste, slag concrete feeding sequence is: first puts into whole scoria coarse-fine aggregate and stirs, then
Add about 1/3 water stirring make scoria surface wettability, be subsequently adding flyash stirring, be eventually adding cement and
The water of residue about 2/3 continues stirring and is simultaneously introduced additive to making concrete.
Beneficial effects of the present invention:
The light aggregate concrete raw material sources that the present invention provides are extensive, and scoria is cheap natural of a kind of lightweight
Material, porous, heat conductivity is little, and flyash falls within profit waste materials, is that major ingredient is made with both materials
Finished product concrete cost less than with label normal concrete, weight ratio normal concrete light about 40%, can be effective
Reduce structural weight per square meter, significantly reduce the basic cost of relevant building.Slag concrete is utilized to develop
Wallboard, has the features such as lightweight, insulation, high-strength, environmental protection, green, energy-conservation and profit be useless, is to be suitable for building
The green building material that commercial application is promoted, can be widely applied in concrete product.
