The important role of steam curing autoclave

Autoclave steam curing fly ash aerated concrete is a necessary condition to obtain strength. By heating, thermostats, cooling and other heat transfer operations, but in the heat content of the water when it does not completely evaporate, vacuum extraction makes aerated block thermal conductivity decreased. In the steam autoclave curing conditions, aerated concrete between the constituent materials in a series of physical and chemical reactions and the generation of the aerated concrete hydration products become different from the original body of the new artificial stone. In the steam autoclave curing process, aerated concrete body will withstand the temperature and humidity changes, resulting withstand various impacts. Autoclave curing process task is to use the autoclave curing autoclave aerated concrete hot and humid conditions inside the hydrothermal reaction sufficiently, so that it has the required quality. At the same time, but also effectively prevent the autoclave curing process may occur is not conducive to the hydrothermal reaction or detrimental effect on the curing conditions and the quality of product. Conservation products must have a certain way, otherwise it will cause some damage products: provide good heat carrier; create a good heat exchange environment; appropriate heating rate; sufficient temperature and time; reasonably cool; body with the necessary strength and temperature as high as possible. And these conditions by saturated steam pressure, vacuum extraction, heating, thermostats, cooling and a series of steps to determine.
