Heat emission at synthesizingtobermorite 11,3 Ả out of lime and quartz amounts to 92 kJ /kg, and at synthesizingxonotlite – to 45 kJ /kg, which raises the temperature ofproducts and pressurein the autoclave. Itwas determined thatat autoclaving the quartz sand based aerocretemixes, the reaction of hydrated calcium silicates synthesisoccursalmost immediately after the autoclave transitionto isothermiccuring mode. The heat emission of this process goes on for 3 – 4 hours. At autoclavingmixes, basedonquartzy and feldspar sands, the heat emission startsafter an hour of isothermiccuring of concretes and goes on up to the end of it.There are given recommendations on regulating the compositionof aerocretehydrated phasesand reducing steam consumption atautoclave curing.
