Abstract
The invention discloses a lightweight thermal-insulation concrete, which is composed of the following raw materials in parts by weight: 70 to 120 parts of cement, 20 to 30 parts of lime, 20 to 80 parts of sand, 30 to 50 parts of coal slag, 25 to 55 parts of aluminium metallurgy slag, 40 to 80 parts of polypropylene fiber, 40 to 70 parts of foaming agent, and 50 to 90 parts of water; wherein the foaming agent is composed of plant-origin fatty acid, and is very safe. The provided concrete has the advantages of cheap raw materials, simple production technology, lightweight, thermal insulation property, energy saving, and environment-friendliness.
Description
Technical field
The invention belongs to building material field, be specifically related to a kind of lightweight insulating concrete.
Background technology
Along with the life idea of modern people and the variation of mode detail, the environmental requirement in buildings is also increased day by day.Heating,Ventilating and Air Conditioning (HVAC), while the living environment bringing comfortable and high-quality, also becomes the rich and influential family in building energy consumption.The heat insulation effect of construction wall is poor, can strengthen the use of Heating,Ventilating and Air Conditioning (HVAC) further, can cause the waste of energy consumption like this.Use the body of wall of conventional concrete construction of buildings, not only increase the load of building self, and considerably increase labour intensity, add construction costs.Along with becoming increasingly conspicuous of energy problem, country more and more payes attention to building energy conservation, and the height of building efficiency directly affects the energy resource safety strategy of China.Lightweight insulating concrete, energy-conserving and environment-protective, compared with conventional concrete, have lightweight, environmental protection, energy-conservation, efficient, of fine quality, cheap feature, have obvious practical value, are the concrete developing direction of future architecture thing.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of lightweight insulating concrete is provided, reduce concrete weight, improve concrete heat-insulating property, meet the energy-conserving and environment-protective requirement of buildings.
The present invention implements by the following technical programs:
A kind of lightweight insulating concrete, is made up of the raw material of following parts by weight: cement 70 ~ 120 parts, 20 ~ 30 parts, lime, 20 ~ 80 parts, sand, cinder 30 ~ 50 parts, aluminium making residue 25 ~ 55 parts, polypropylene fibre 40 ~ 80 parts, whipping agent 40 ~ 70 parts, 50 ~ 90 parts, water.
Further, described lightweight insulating concrete can be made up of the raw material of following parts by weight: cement 100 parts, 30 parts, lime, 50 parts, sand, cinder 30 parts, aluminium making residue 25 parts, polypropylene fibre 70 parts, whipping agent 65 parts, 90 parts, water.
Further preferably, described lightweight insulating concrete can be made up of the raw material of following parts by weight: cement 85 parts, 22 parts, lime, 60 parts, sand, cinder 45 parts, aluminium making residue 40 parts, polypropylene fibre 55 parts, whipping agent 50 parts, 80 parts, water.
In such scheme, described whipping agent can be vegetablefats acid, is safety and environmental protection health product, can not works the mischief to human body.
The preparation method of this lightweight insulating concrete and the auxiliary materials of interpolation can concrete production technology routinely carry out.
Whipping agent in material of the present invention can make concrete build shaping after, after natural curing, form a large amount of pore closed at inside concrete, thus alleviate concrete weight, improve concrete heat insulation effect.Polypropylene fibre is added in concrete, can reduce or prevent concrete premature cure stage after building, plastic shrinkage and tiny crack is caused because of bleeding and moisture loss, also the tiny crack can reduce, prevented from the concrete hardening later stage from producing desciccation crack and temperature variation causing, thus improve the performances such as concrete antiseepage, freeze proof, resistant abrasion.Simultaneously because a large amount of fiber is randomly distributed in concrete, after making the deformability of concrete structure, incipient crack, residual strength, toughness all improve.
Advantage of the present invention is: raw materials for production low price, and component proportion is simple, does the concrete prepared and has lightweight, insulation, advantage that intensity is high, and energy-conserving and environment-protective.
