Shandong Shengya Machinery Co., Ltd. specializing in the production of various types of brick, brick machine, brick machine, hollow brick, pavement brick and other equipment of the old brick factory.
     Unburned cement brick materials: fly ash, coal gangue, mountain sand, river sand, construction waste, carbide slag, slag, slag, waste and so on. The following is a fit with unburned unburned cement brick cement brick production of various raw materials ratio range:
① ash ratio. The total proportion of fly ash, without making sand, generally 50% to 75%; in the case of building sand, generally 60% to 90%; which, by the fine grinding of high ash can 10% -20% of total ash.
② aggregate amount. The use of manufactured sand fly ash aggregate, the amount can be controlled in the ratio of 30% -40% of the total amount, in order to facilitate the increased utilization of fly ash, high dosage. The use of other species aggregate, to ensure the strength of unburned situation, mixed as little as possible, so that the relative increase of fly ash content. Therefore, the aggregate amount of other varieties should be 20% -30%. If coarse sand, about 20% can be. Sand density is too large, it is not appropriate to use.
Preferred species for slag aggregate, followed by water quenching slag, again red gangue (natural gangue and gangue calcined), garbage slag. Other types of heavy construction waste such as slag aggregate, Gravel mining, artificial sand and natural sand, stone industry Gravel and other waste can be used, but the density, activity and other considerations, as before several active lightweight aggregate Excellent.
③ the amount of cement. Preferred ordinary portland cement, especially high grade kiln ordinary portland surplus. Other varieties of cement in general should not be optional.
The ratio of the amount of cement vary widely. When using the higher activity of fly ash, fly ash and some high fine or ultrafine grinding, while using autoclave or steam when raising process, cement can not. When using the higher activity of fly ash, fly ash is no longer part of the high fine or ultrafine grinding, while using steam curing process, the cement can be 1% to 3%; when the general activity of fly ash and steam curing when the amount of cement may be 3% to 5%; when the ash activity in general but using the Nature Conservancy, the amount of cement for 7% -10%.
   The above amounts are also affected by the impact molding machine. When using high-performance machine, the amount of cement in 1% to 5%, while poor performance when using the machine, the amount of cement for 6% -10%.
