steam curing fly ash brick machine

Fly ash brick machine with autoclave curing ,steam curing

High quality high strength

focuses on high quality lime-sand brick, fly ash brick manufacturing process

Technology support: Supply complete set production line equipment, from site planning to equipment manufacturing, installation, adjustment, staff training and technical support among production process, temin machinery will sincerely cooperate with you.

The curing principle as follow:Lime-sand (fly ash) brick is mainly rely on quick lime the effective CaO and sand of SiO2 0.8 Mpa above pressure with steam (174.5 ℃ above), under the condition to go on the thermal synthetic reaction. To create all kinds of silicate gel material, for the most part for hydrated calcium silicate and a small amount of magnesium silicate etc, with aggregate sand firmly cement together, forming a certain structure strength. In the above process after equipment pressure molding for high strength lime-sand (fly ash) brick.The reaction process(Hydraulic brick machine)

CaO + H2O - Ca (OH) 2 + 15.5 kilocalorie (mixed YouTi bentonite)

Ca (OH) 2 + SiO2 + (n-1) H2O 174.5? Saturated steam

CaO * SiO2 * nH2O (calcium silicate) calcium silicate brick and block
