Steam Autoclave For Lime Based Fly Ash Bricks

2016-08-08

Those lime based steam autoclaved fly ash bricks are urgently needs in construction fields. But, each fly ash bricks must through steam curing in the chamber of autoclave before they are used. Our ZG company has high technology and rice experience in autoclaves, those kind of pressure vessels manufacturing. Here is an example.
In a coal fired thermal power plants in Turkey, it produce 10 million tonnes of fly ash as waste per year. And part of this waste is utilized as a raw material in the production of fly ash bricks. In this passage, we want to know more about the production of steam autoclave for lime based fly ash bricks.
Before Steam Curing, fly ash, sand and hydrated lime mixtures were steam autoclaved under different test conditions to produce brick samples. An optimum raw material composition was found to be a mixture of 68% fly ash, 20% sand and 12% hydrated lime. The optimum brick forming pressure was 20 MPa.


Then, those semi-finished fly ash bricks are put into the chamber of autoclave. The optimum autoclaving time and autoclaving pressure were found 6 h and 1.5 MPa, respectively. The compressive strength, unit volume weight, water absorption and thermal conductivity of the fly ash–sand–lime bricks obtained under optimum test conditions are 10.25 MPa, 1.14 g/cm3, 40.5% respectively. As a result, it was possible to produce good quality light weight bricks from the fly ash blocks plant.
To autoclave’s inner diameter and length, our company accept personal tailor. Our engineer can produce different size industrial autoclaves with you industry requirements.
