Изобретение относитс  к промышленности строительных материалов и может быть иснользовано заводами  чеистых бетонов.The invention relates to the building materials industry and can be used by cellular concrete plants.

По основному авт. св. № 141423 известен способ формовани   чеистобетонных, например газосиликатных изделий, по которому сырьевую смесь заливают в форму и выдерживают до вспучивани , затем производ т срезку «горбушки и прокатку с последующей термообработкой .According to the main author. St. No. 141423 is a known method for forming cellular concrete, for example, gas silicate products, by which the raw material mixture is poured into a mold and held until it expands, then cut and roll is rolled followed by heat treatment.

Недостатком такого способа  вл етс  то, что в случае использовани  газосиликатной сырьевой смеси на высокоэкзотермичной и быстрогас щейс  извести через 10-40 мин после прокатки на прокатанной поверхности по вл ютс  трещины.The disadvantage of this method is that in the case of using a gas-silicate raw material mixture, cracks appear on the highly exothermic and fast-extinguishing lime 10-40 minutes after rolling.

Целью изобретени   вл етс  уменьшение трещинообразовани  и повышение заводской готовности изделий из газосиликатобетона.The aim of the invention is to reduce cracking and increase the factory availability of gas silicate concrete products.

Достигаетс  это тем, что обычным способом приготовл ют газосиликатную смесь с оптимальным количеством воды, определ емым расчетом, затем смесь заливают в форму и выдерживают до вспучивани  и схватывани .This is achieved by preparing a gas-silicate mixture with an optimal amount of water in a usual way, determined by calculation, then the mixture is poured into a mold and held until it expands and sets.

Способ заключаетс  в следующем.The method is as follows.

После вспучивани  смеси и срезки части «горбушки ввод т новую дополнительную операцию: изделие выдерживают в течение времени, необходимого дл  остывани  срезанной поверхности до температуры, не превышающей 40-50°С, а уже после этого прокатывают .After the mixture is expanded and a piece of cut is cut, a new additional operation is introduced: the product is kept for the time necessary to cool the cut surface to a temperature not exceeding 40-50 ° C, and after that it is rolled.

С целью ускорени  охлаждени  поверхность издели  в процессе выдерживани  обдувают струей воздуха.In order to accelerate the cooling, the surface of the product is held with an air jet during the holding process.
