Abstract
The invention discloses lightweight aggregate concrete, and relates to the field of building materials. The lightweight aggregate concrete is prepared from aggregate, adhesives, additives, surface layer special adhesives and water. Aggregate is prepared from 45-50% of aerated concrete building block crushed aggregates, 30-35% of foamed cement heat preservation board crushed aggregates, 15-20% of fire coal slag and 5-8% of other materials according to the volume ratio through smashing, screening and other procedures. In order to solve the problem that a traditional construction mode of heat preservation and cushion is too high in manufacturing cost, heat preservation waste is used for heat preservation and cushion, a series of problems of heat preservation, sound heat preservation, filling, slope finding, environment protecting and the like are solved, and construction cost is reduced.
Description
Technical field
The present invention relates to building material field, be specifically related to a kind of lightweight aggregate concrete.
Background technology
According to " General Office of the State Council is about forwarding State Development and Reform Commission, house town and country construction portion green building row
The notice of dynamic scheme " etc. the requirement of laws and regulations, from 2015, point family floor of all residential housings
All should meet the requirement of insulation and sound insulation simultaneously.But, this most always puzzlement design and construction
The difficult problem of personnel.First being how to ensure construction quality and safety, in practice, many designers will divide family
The insulation of floor is arranged under plate (i.e. ceiling position), advantage of this is that and is easy to supervision, either with or without doing,
Do many thickness very clear, nor the quality of bed course can have been affected, but the harm of do so has been " coming off "
Risk the most prominent；Also have and heat-insulation layer is arranged under bed course, the most first do heat-insulation layer, then run business into particular one
Stone concrete bed course, advantage of this is that and be possible to prevent " coming off ", harm be take space big,
Hollowing cracking risk is big, the later stage is fixed the anchoring piece of timber floor and is difficult to " taking root "；Next to that how to reduce build
The load built, in existing insulation, acoustic construction mode, generally exists that structure is complicated, load is notable
The problem increased；It is how to reduce building cost again, at present, heat insulating and sound insulating structure current on market,
Its comprehensive cost is all at 60 yuan/about m2, relatively costly.Therefore, a kind of reasonable price of research invention,
Have " special concrete " of the functions such as insulation, sound insulation, filling, bed course be levelling simultaneously concurrently, have become as and build
Build point family floor insulation, a task of top priority for sound insulation.
Summary of the invention
Present invention aims to defect and the deficiency of prior art, it is provided that a kind of lightweight aggregate concrete,
It is for the too high problem of " insulation+bed course " this conventional construction mode cost, utilizes insulation waste material, holds concurrently
Gu Baowen and bed course, solve insulation, sound insulation, fill, look for the series of problems such as slope, environmental protection, reduce
Construction cost.
For achieving the above object, the technical solution used in the present invention is: it comprises following raw material: aggregate,
The special adhesive of adhesive, additive, surface layer and water；Described aggregate by air-entrained concrete building block particle,
The operations such as cement insulation board particle, coal-fired waste residue etc. are raw material, size-reduced, screening prepare, its
In the volume accounting of each raw material be: air-entrained concrete building block particle 45-50%, cement insulation board particle
30-35%, coal-fired waste residue 15-20%, other 5-8%.
Described adhesive is with cement as rubber cement, is aided with what flyash, additive and ZGS prepared.
Described additive is
Raw material prepares, and it is for improving the mobility of concrete, the shrinkage value of compensation material, improving material
Hydrophobicity performance and operable time.
The special adhesive of described surface layer, is with cement as rubber cement, is aided with the materials such as water conservation, cracking resistance, slow setting
Material prepares, and it, for being incubated the receipts light of terrace, to improve the intensity of surface layer, prevents surface layer dusting.
The invention have the benefit that
1. it has expanded the use function of concrete, not only solves the problem that construction floor is levelling, simultaneously
Herein in connection with construction of leveling blanket, synchronize to solve insulation, sound insulation, fill, look for the series of problems such as slope, environmental protection.
2. it breaches point the traditional construction technique of family floor insulation and a make, makes full use of production-goods again
Source, uses the construction technology and homogeneity material survived for a time, improve to greatest extent efficiency of construction,
Reduce building cost；
3. that reduce construction cost, the comprehensive cost of 40 yuan/about m2, be only equivalent on market current
The 2/3 of insulation material.
Detailed description of the invention
The present invention is further illustrated below.
The present embodiment the technical scheme is that it comprises following raw material: aggregate, adhesive, additive,
The special adhesive of surface layer and water；Described aggregate is by air-entrained concrete building block particle, cement insulation board
The operations such as particle, coal-fired waste residue etc. are raw material, size-reduced, screening prepare, the volume of the most each raw material
Accounting is: air-entrained concrete building block particle 45-50%, cement insulation board particle 30-35%, fire coal are useless
Slag 15-20%, other 5-8%.
Described adhesive is with cement as rubber cement, is aided with what flyash, additive and ZGS prepared, its
In the quality accounting of each composition be: cement 63%, flyash 14%, additive 2%, ZGS21%.
Described additive is
Raw material prepares, and it is for improving the mobility of concrete, the shrinkage value of compensation material, improving material
Hydrophobicity performance and operable time.
The special adhesive of described surface layer, is with cement as rubber cement, is aided with the materials such as water conservation, cracking resistance, slow setting
Material prepares, and it, for being incubated the receipts light of terrace, to improve the intensity of surface layer, prevents surface layer dusting.
Having the beneficial effect that of this detailed description of the invention
1. it has expanded the use function of concrete, not only solves the problem that construction floor is levelling, simultaneously
Herein in connection with construction of leveling blanket, synchronize to solve insulation, sound insulation, fill, look for the series of problems such as slope, environmental protection.
2. it breaches point the traditional construction technique of family floor insulation and a make, makes full use of production-goods again
Source, uses the construction technology and homogeneity material survived for a time, improve to greatest extent efficiency of construction,
Reduce building cost；
3. that reduce construction cost, the comprehensive cost of 40 yuan/about m2, be only equivalent on market current
The 2/3 of insulation material.
The above, be merely to illustrate technical scheme and unrestricted, ordinary skill people
Other amendment or equivalent that technical scheme is made by member, without departing from skill of the present invention
