Abstract
The invention discloses an autoclaved fly ash brick and relates to the technical field of building materials. The autoclaved fly ash hollow brick is characterized by consisting of the following components in percentage by weight: 35 to 45 percent of fly ash, 20 to 28 percent of carbide slag, 20 to 30 percent of yellow sand, 7 to 14 percent of stone chips and 1 to 2 percent of gypsum. The autoclaved fly ash brick manufactured by the scheme has the advantage that: according to detection, various technical indexes reach the national standard. A great amount of carbide slag is added into the raw materials, so the cost of the autoclaved fly ash brick is reduced.
Description
Technical field
The present invention relates to a kind of fly ash hollow brick, specifically be a kind of be the autoclaved fly ash brick of main raw material with flyash.Belong to the building materials technical field.
Background technology
At present, the autoclaved fly ash hollow brick generally is to be main raw material with the flyash of power plant emission and coal gangue, is equipped with cement, lime, yellow sand, make through the High Temperature High Pressure maintenance after batch mixing, digestion, moulding, generally more than 174.5 ℃, operating pressure is more than 0.8MPa for vapor temperature again.Make the active integral part in the brick fully carry out hydro-thermal reaction, thus the intensity height of brick, performance tends towards stability. and the brick of producing has higher degree of compactness and intensity.The weak point of above-mentioned autoclaved fly ash hollow brick is: the addition content of flyash is low, and lime, cement price are higher, causes the cost height of brick.
Summary of the invention
For overcoming the existing high drawback of autoclaved fly ash brick cost, the invention provides a kind of autoclaved fly ash brick that adds carbide slag, and addition is higher, thereby has reduced the cost of autoclaved fly ash hollow brick.
Technical scheme of the present invention is as follows: a kind of autoclaved fly ash hollow brick is characterized in that: be made up of flyash, carbide slag, yellow sand, aggregate chips and gypsum, the weight percent of each component is:
Flyash 35～45%
Carbide slag 20～28%
Yellow sand 20～30%
Aggregate chips 7～14%
Gypsum 1～2%.
The preferred weight percent of above-mentioned flyash, carbide slag, yellow sand, aggregate chips and gypsum is:
Flyash 38%
Carbide slag 26%
Yellow sand 28%
Aggregate chips 8%
Gypsum 2%.
The preparation method of above-mentioned autoclaved fly ash brick is characterized in that: at first in proportion the batching, add water stir water ratio be the compound of 11-14%, again with compound digestion, mixed grind, moulding, after make autoclaved fly ash brick after the High Temperature High Pressure maintenance;
Among the above-mentioned preparation method, maintenance pressure is 1.2-1.3MPa, and curing temperature is 185 1 193 ℃, and curing time is 8 one 12h.
With the autoclaved fly ash brick that such scheme is made, after testing, every technical indicator all is up to state standards.
The invention has the beneficial effects as follows: the present invention has added a large amount of carbide slags in raw material, has reduced the cost of autoclaved fly ash brick.
Embodiment
Embodiment 1:
Batching: flyash 38%, carbide slag 26%, yellow sand 28%, aggregate chips 8%, gypsum 2%.
Manufacturing process: above-mentioned raw materials is added water stir to such an extent that water ratio is the compound → with compound digestion → mixed grind → moulding → after make autoclaved fly ash brick after the High Temperature High Pressure maintenance of 11-14%; Its maintenance pressure is 1.3MPa, and curing temperature is 190 ℃, and curing time is 8h.
The ultimate compression strength of the autoclaved fly ash brick that makes after testing can stand the freeze proof requirement of 15 freeze-thaw cycle greater than 20MPa.
Embodiment 2:
Batching: flyash 40%, carbide slag 25%, yellow sand 25%, aggregate chips 7%, gypsum 2%.
Manufacturing process: above-mentioned raw materials is added water stir to such an extent that water ratio is the compound → with compound digestion → mixed grind → moulding → after make autoclaved fly ash brick after the High Temperature High Pressure maintenance of 11-14%; Its maintenance pressure is 1.3MPa, and curing temperature is 190 ℃, and curing time is 8h.
The ultimate compression strength of the autoclaved fly ash brick that makes of two kinds of batchings can stand the freeze proof requirement of 15 freeze-thaw cycle all greater than 15MPa after testing.
