Abstract
The present invention is a kind of holllow building block for building and preparation thereof, and feature is by pearlstone 4-14%, industrial slags 50-75%, and cement 20-40% adds an amount of water and forms, and the step of its preparation is metering proportion, mixing stirring, discharging moulding, foster naturally stove.Its unit weight is 628-817kg/m
3, intensity reaches 2.24-3.96mPa, and antifreezing test meets national standard, whitewashes as body of wall and does not flake, do not ftracture.Adopt this technology to utilize industrial slags in a large number, turn waste into wealth, reduce and pollute, good economic benefit is not only arranged, very high social benefit is also arranged.
Description
The invention relates to a kind of structure of construction wall, specifically relate to a kind of body of wall that constitutes by holllow building block.This holllow building block is made up of pearlstone, industrial slags and cement, an amount of water, and the preparation process of forming.
The holllow building block of prior art mainly is crushed stone concrete and ceramsite concrete hollow block, but because the big (900Kg/m of its unit weight
3More than), fail to be used widely, especially the antidetonation area.Solid block mainly is the building block that gas concrete is made, and its unit weight is generally 700Kg/m
3About, because unit weight is lighter, the energy antidetonation, in multilayer, Highrise buildings, be widely used, but the building block that this gas concrete is made, and its weak point is that water-intake rate is big, a surfacing and a powder, doing when whitewashing,, even brushing measure such as 107 glue mud although adopt cleaning, water, after whitewashing soon still often big area flake, ftracture, cause and do over again, increase cost, waste material and man-hour.Another weak point of the building block that gas concrete is made is that intensity is lower, and anti-freezing property is poor, as enclosure wall quality accident takes place easily.
The purpose of this invention is to provide a kind of is glueing material with cement, is first packing material with pearlstone, to alleviate unit weight, is the holllow building block that second packing material is formed with slag, and unit weight is light, and intensity height, body of wall whitewash and do not flake, do not ftracture.
Another object of the present invention is to provide the step of preparation process of this holllow building block.
The objective of the invention is to realize by following technical scheme.
The present invention includes cement, slag, it is characterized in that by pearlstone, industrial slags and cement, add an amount of water and form, the weight % ratio of its composition is:
Pearlstone, 4～14
Industrial slags 50～75
Cement 20～40
Add suitable quantity of water
Pearlstone is for mixing bulk cargo, and its unit weight is 40～80Kg/m
3, the particle diameter requirement of industrial slags is＜10mm.Cement is 〉=325#.
Preparation of the present invention is characterized by batching → mixing stirring → discharging moulding → natural curing.
Batching is according to the composition weight % ratio weigh batching of the mixture of expanded perlite hollow building block;
Mix and stir,, with mixing and stirring half a minute in industrial slags and the cement input stirrer, add suitable quantity of water earlier, stirred 1～2 minute, drop into pearlstone again, stirred 1 minute according to the batching of weighing;
The discharging moulding, the compound after the stirring is poured out stirrer, the moulding of pressurization pressure machine;
Natural curing, the expanded perlite hollow building block after the moulding, at normal temperatures, it is wetting that watering keeps, natural curing 28 days.
The present invention is through Fuyang, Anhui Province regional architecture engineering corporation trial report, and its unit weight is 628～817Kg/m
3, intensity is 2.24～3.96mpa, antifreezing test meets the requirements with reference to JC315-82 " autoclave aerated concrete building block " standard.
The present invention is a kind of have light thermal-insulation, heat insulation, sound-absorbing and good multifunctional building block of anti-freezing property, can alleviate the own wt of buildings, and beam, post section in the buildings are reduced, plate thickness attenuate, foundation ' s bottom area and highly all reducing.Application of the present invention can not only be increased economic efficiency for the unit of undertaking the construction of, and has increased the shock resistance of buildings, has good social benefit.
Another characteristics of the present invention are, its surfacing is coarse again, water in right amount when whitewashing, and it is good especially that it whitewashes effect, do not flake, and do not ftracture, overcome air-entrained concrete building block have flake, the rimose defective.
It is big that the present invention consumes the industrial furnace quantity of slag, makes full use of industrial slags, reduces the pollution of urban industry rubbish, can save the good farmland greatly again.
Preparation technology of the present invention is simple, and equipment is few, and fund input amount is little, adopts natural curing, reduces cost, and good economic return is arranged.
By the following examples, the present invention is further described.
Embodiment 1:
Present embodiment is selected unit weight 60Kg/m for use
3, the pearlstone of mixing bulk cargo, the particle diameter＜10mm of industrial slags, air storage was watered water saturates 7～10 days, and the label of cement is 〉=325#.Water can be used tap water, well water or river, has no special requirements.The composition weight % ratio of present embodiment is:
Pearlstone 6.7
Industrial slags 68.4
Cement 24.9
Add an amount of water.
The preparation process of present embodiment is by the various material fiting ratio meterings of its composition.Earlier the cement of 68.4% industrial slags and 24.9% is dropped into amalgamator and stir half a minute, add suitable quantity of water, continue to be stirred to evenly, about 1～2 minute, drop into 6.7% pearlstone again and stir half a minute.Carry out discharging after the stirring, pour pressing machine compression moulding into, become expanded perlite hollow building block.With its natural curing at normal temperatures 28 days, it is wetting that watering keeps then.Its unit weight is 675Kg/m
3, intensity reached 1.09mpa in 7 days, and intensity reached 3.38mpa in 28 days, and antifreezing test complies with the national standard requirements.As winter, temperature can add frostproofer below 5 ℃ in raw material mixes and stirs, and between preserving period, adds plastics film or straw bag and covers or adopt steam curing.The expanded perlite hollow building block of present embodiment production is made body of wall, whitewashes at 10,000 square metres of areas through test, and bisque does not flake, do not ftracture.Before whitewashing, should will be irrigated by the metope water of powder.
