Description
Technical field
The present invention relates to a kind of concrete light blockwork material of mixing silica flour, the invention still further relates to a kind of above-mentioned method of mixing the concrete light blockwork material of silica flour for preparing.
Background technology
In the prior art; Producing concrete lightweight wall material generally all is to adopt cement, lime, sand or flyash, gypsum, aluminium powder etc. to be made, and these concrete lightweight wall material intensity generally are lower than 5Mpa, and water-absorbent is strong; Hanging force is not enough, and production cost is higher relatively.
Summary of the invention
The objective of the invention is provides a kind of and can make full use of industrial residue in order to overcome weak point of the prior art, the concrete light blockwork material of mixing silica flour that production cost is relatively low;
Another object of the present invention provides a kind of above-mentioned method of mixing the concrete light blockwork material of silica flour for preparing.
In order to achieve the above object, the present invention adopts following scheme:
A kind of concrete light blockwork material of mixing silica flour; It is characterized in that forming, wherein by weight described gelling material: mine tailing: haydite: boiler slag: water: silica flour 1: 1～2.6: 1.3～3.4: 1.5～3.5: 0.3～0.5: 0.11～0.43 by gelling material, mine tailing, haydite, boiler slag, water and silica flour.
The aforesaid concrete light blockwork material of mixing silica flour is characterized in that described gelling material is a flyash.
The aforesaid concrete light blockwork material of mixing silica flour is characterized in that described gelling material is silicate cement or the ordinary Portland cement more than 32.5 grades.
The present invention prepares the aforesaid method of mixing the concrete light blockwork material of silica flour of power, it is characterized in that may further comprise the steps:
A, reach specific surface area 400-500m greater than 90% building sand or the quartzite after the fragmentation through dry, grinding with dioxide-containing silica
2The silica flour of/kg;
B, with above-mentioned silica flour and gelling material, mine tailing, haydite, boiler slag, water, in 0.11～0.43: 1: 1～2.6: 1.3～3.4: 1.5～3.5: 0.3～0.5 ratio adds together in the stirrer of forced action type and stirs;
C, in mould, evenly be covered with material,, behind natural curing or the atmospheric steam curing, at 175 ℃ of-190 ℃ of following high-pressure curing 2-6 hours, promptly get again through extrusion molding.
Aforesaid method is characterized in that silica flour described in the step B and gelling material, mine tailing, haydite, boiler slag, water churning time in the stirrer of forced action type is 180S～240s.
Aforesaid method, the temperature that it is characterized in that the atmospheric steam curing described in the step C is 60～80 ℃, the time is 1～3 hour.
In sum, beneficial effect of the present invention:
One. the employed boiler slag of the inventive method source is sufficient, because a kind of waste residue of slag boiler emission when being the fuel-burning power plant generating can economize on resources after using, turns waste into wealth, so source abundance.
Two. silica flour can form with general river sand or silica sand grinding, and river sand or the easy grinding of silica sand.Because but admixture silica flour equivalent replaces cement, practice thrift cement consumption greatly, reduce hydration heat, reduce thermal stress and the concrete crack of causing; Improve the microtexture of cement slurry, increased the concrete density, thereby improved concrete strength and weather resistance; Make its materials for wall from heavy and light; Prolong work-ing life, and mechanical property is being much higher than aerated concrete wall material aspect resistance to compression and the hanging force, has good economic and social benefit.
Three. the price of cement generally surpasses 400 yuan/ton at present, and the cost value of silica flour is about 140 yuan/ton, and silica flour of the present invention can replace 10～40% cement, effectively reduces cost.Gas concrete generally will use 42.5 class g cements, and 32.5 class g cements are generally used in the lightweight ceramisite concrete building block, from and reduced cost.
