Fly ash unburned ready to use as curing agents, the use of steam curing process and made unburned, referred to as fly ash or fly ash unburned bricks. Ash unburned test method with the same basic unburned soil and cement. It is different from unburned cement fly ash increases the amount of strength not been rising, but after a fly ash content, the intensity will not be increased. In addition, the strength of fly ash unburned also its steam curing methods. General steam curing temperature is higher, the higher the intensity, the higher pressure steam curing intensity is also higher. Its strength is closely related with the production process.

    Example test with law

    Ash unburned test with law, basically similar to cement unburned, mainly determine the following relationships:

    (1) the strength of fly ash brick to reach more than 10MPa, raw performance consistent with each other.

    (2) ash content and strength of the relationship. Batch test with 6 groups, at a molding pressure of 20-25MPa, unburned ash formed. Steam curing at 100 ℃ for 24 hours, cooled, and tested for compressive strength, flexural strength.

    (3) forming pressure and the strength of the relationship. Optional 25MPa compressive strength sufficient to achieve brick l0MPa more.

    (4) Select the curing temperature and time. According to steam curing silicate hydration products of theoretical analysis and practical experience, the general said, steam curing temperature, the higher the intensity of the brick, the higher pressure steam curing, brick strength is also higher. But brick factory purchase autoclave investment is too large, too costly. Generally use steam curing is more convenient, brick strength can reach 10MPa, to meet the requirements.

    Curing time relationship with brick strength within a certain range, but also the length of time the intensity increases, but in general the conservation of 12-24 hours is sufficient. To save energy, the general l00 ℃ steam curing. 24 hours brick strength of 10MPa or more.
