Autoclaved fly ash unburned brick production and application of


Balance. Obviously, how to make use of fly ash as a resource,[link widoczny dla zalogowanych], turning waste into treasure, has become a pressing priority. Fly ash-based materials for fly ash bricks, is an important part of the wall of reform, but also for the application of ash channels opened up a wing. Second, the production of unburned unburned autoclaved brick Jian-free brick production, changes in the past to be burning brick with fly ash, steam curing practices, but the pink grip the ash, lime, then after a certain mixing ratio, pressure turn shape, and then by chemical solution can be removed from the calcined Baptist collapse, Jian Yang and other processes, simplify processes, reduce energy consumption and production costs, the process shown below. I l lime ash 』process glistening brick chart application of the technology, simple technology, low power consumption, short production cycle, each batch production cycle ~ brick-like only 7 days. Ash content of 70 to 80 above. Third, the double-brick free performance test 1, the water immersion test water immersion l8 months later, after testing, only l0 mm week immersion layer 2, the strength test after test, a single block of minimum 12.8 Ⅻ Pa, the average l6.7MPa. 15 the industry standard for fly ash brick fly ash bricks JC239 ~ 91 stipulates that the minimum value of not less than one block IIMPa, the average is not less than 15MPa,[link widoczny dla zalogowanych], meet industry standards 3, freeze-thaw test case in a 20'C Next, the l6 freezing and thawing cycles can not afford to skin cracking. 4,[link widoczny dla zalogowanych], detected by the detection of brick, brick made by the compressive strength of the sample average 87MI ~,[link widoczny dla zalogowanych], shear strength for the 0.4l Ⅻ Pa, consistent with masonry design (GBJ3 ~ 73) the relevant provisions. 5,[link widoczny dla zalogowanych], saline-alkali salt with 6 6 base synthesis salamander concentrations of salt water immersion, total 871 days, no change. Fourth, the application is currently in the Tangshan area, the bricks are a better application. Tangshan Feng County has used the bricks to build a hotel, plant, water tower and chimney and other buildings. Construction Committee of Tangshan on July l ∞ 0 issued a \The bricks are constantly expanding range of applications, product demand, have been built in the country for several production lines, creating benefits for the community. On conservation land and coal, reducing environmental pollution is important. A l9 a mutual
