B, flyash, granulated blast-furnace slag and lime putty are taken by weighing preparation by described building block weight ratio, add the water of raw material gross weight 5-10%, after stirring, be sub-packed in the building block mould pressurization and vibration moulding;
C, with the building block stacking, add a cover to 24 hours with plastics film, add a cover film again after opening film and watering, watered once in per 8 hours, continue 7 days, then demoulding natural curing to 28 day.
The another kind of implementation of purpose of the present invention:
Building brick without firing and steaming of the present invention; with flyash, granulated blast-furnace slag and lime putty is raw material; its proportioning is counted with weight %: flyash: 30-50%; granulated blast-furnace slag: 40-60%; lime putty: 10-15%; described flyash is II level, III level ash, and the grain graininess of described granulated blast-furnace slag is 150-600 μ m.
Preferably, described light-weight aggregate building brick without firing and steaming, the proportioning of described component is counted with weight %: flyash: 30%, granulated blast-furnace slag: 60%, lime putty: 10%, described flyash is II level ash, the granularity of described granulated blast-furnace slag is 150 μ m.
Another is preferred, described light-weight aggregate building brick without firing and steaming, and the proportioning of described component is counted with weight %: flyash: 50%; granulated blast-furnace slag: 40%; lime putty: 10%, described flyash III level ash, the granularity of described granulated blast-furnace slag is 300 μ m.
One is preferred again, described light-weight aggregate building brick without firing and steaming, and the proportioning of described component is counted with weight %: flyash: 35%; granulated blast-furnace slag: 50%; lime putty: 15%, described flyash III level ash, the granularity of described granulated blast-furnace slag is 600 μ m.
The manufacturing process of described building brick comprises the following steps:
A, granulated blast-furnace slag is pulverized by described granularity and sieved;
B, flyash, granulated blast-furnace slag and lime putty are taken by weighing preparation by described building brick weight ratio, add the water of raw material gross weight 5-10%, after stirring, be sub-packed in the stock mould pressurization and vibration moulding;
C, with the adobe stacking, add a cover to 24 hours with plastics film, add a cover film again after opening film and watering, watered once in per 8 hours, continue 7 days, then demoulding natural curing to 28 day.
The mechanism of building block of the present invention, brick and manufacturing process thereof is:
By the compound of assembly of the present invention preparation in adding the water whipping process, the Ca in lime putty (OH)
2Exciting under, grain graininess is less than the Al of 60 μ m glassiness structures in the granulated blast-furnace slag
2O
3With CaO hydration reaction taking place, generate hydraulicity gum materials such as hydrated calcium silicate, drated calcium aluminate, with coarse particles gluing in the compound together, has quickened the hydration reaction of compound; Simultaneously, the Ca in the lime putty (OH)
2With SiO
2, Al
2O
3Play hydration reaction and generate materials such as hydrated calcium silicate, drated calcium aluminate.
Two kinds of major ingredient flyash, granulated blast-furnace slags of the present invention are active material; flyash mainly is made up of a large amount of sial vitreums and a small amount of carbon granules; and granulated blast-furnace slag is to be the granulation vitreous material of major ingredient with silicate, ca aluminosilicate and calcium chloride, has good gelling property.The activity of flyash and granulated blast-furnace slag belongs to inert particle during greater than 60 μ m at its grain graininess, and activity can not obtain performance, and at its grain graininess during less than 60 μ m, grain graininess is more little, and activity is high more; Grain graininess with granulated blast-furnace slag in this technology is crushed to 150-600 μ m, and through measuring and calculating, wherein granularity accounts for 5-10% less than the particle of 60 μ m, this part SiO
2, Al
2O
3Destructurized with the glassiness of CaO, activity is excited out, and hydration reaction takes place.As the above analysis, above-mentioned mechanism of the present invention is similar to the reaction mechanism of cement, and therefore, the present invention substitutes the cement that adds in the existing technology with the granulated blast-furnace slag of 5-10% granularity less than 60 μ m, has reduced production cost.
The main raw material flyash of building block of the present invention, brick, granulated blast-furnace slag are light material; building block, the brick produced in the building block of producing, brick and the prior art are compared; in light weight; be used for the weight that buildings can reduce buildings as in-filled block, brick, reduce the cost of building.These two kinds of raw materials are industrial residue simultaneously, and the source is sufficient, and is cheap, meets Circular Economy Theory and national sustainable development policy.Manufacture craft of the present invention, technology is simple, and quality product is controlled easily, is suitable for extensive Industry Promotion and uses.
No-baked no-steamed building of the present invention detects through building materials industry product quality supervision and inspection station, Henan Province with building block, brick, every index all meets or exceeds the national standard of relevant building block GB15229-2002, building brick JC239-1991, be qualified product, survey report is as follows:
