Description

Изобретение относится к производству ячеистых бетонов, в частности пенобетонов.The invention relates to the production of cellular concrete, in particular foam concrete.

Известна смесь для изготовления ячеистого бетона (пенобетона), включающая, мас. %: портландцемент 30-31; пенообразователь 0,15-0,25; вода 33-34; зола ТЭС - остальное [1].A known mixture for the manufacture of cellular concrete (foam), including, by weight. %: Portland cement 30-31; a foaming agent 0.15-0.25; water 33-34; ash TPP - the rest [1].

Задача изобретения состоит в повышении прочности пенобетона.The objective of the invention is to increase the strength of foam.

Технический результат достигается тем, что сырьевая смесь для изготовления: пенобетона, включающая портландцемент, пенообразователь, воду, в качестве пенообразователь содержит пенообразователь ПБ-2000 и дополнительно - штапельное стекловолокно при следующем соотношении компонентов, мас. %: портладцемент 55,0-60,0; пенообразователь 0,2-0,25; штапельное стекловолокно 0,25-0,35; вода 39,5-44,45.The technical result is achieved in that the raw material mixture for the manufacture of: foam concrete, including Portland cement, a foaming agent, water, as a foaming agent contains a foaming agent PB-2000 and additionally staple fiberglass in the following ratio of components, wt. %: cement cement 55.0-60.0; foaming agent 0.2-0.25; staple fiberglass 0.25-0.35; water 39.5-44.45.

Составы смеси приведены в таблице.The compositions of the mixture are shown in the table.

Пенообразователь ПБ-2000 соответствует требованиям ТУ 2481-185-05744685-01, плотностью 1000-1200 кг/м3, pH 7-10, кратность пены рабочего раствора с объемной долей пенообразователя 4%, устойчивость пены не менее 360 с.The PB-2000 foaming agent meets the requirements of TU 2481-185-05744685-01, with a density of 1000-1200 kg / m 3 , pH 7-10, the multiplicity of the working solution foam with a volume fraction of the foaming agent of 4%, the foam stability of at least 360 s.

В пеногенераторе взбивают пену из смеси пенообразователя с водой. Смешение всех компонентов бетона осуществляют в шнековом смесителе, в который сначала подают сухие компоненты: портландцемент и штапельное волокно, а затем - приготовленную пену. Из смесителя приготовленную смесь равномерно распределяют по площади предварительно смазанных маслом металлических форм и подают на тепловлажностную обработку, которую проводят по режиму 3+9+3 ч при температуре изотермической выдержки 90°C. Затем готовые изделия извлекают из форм и транспортируют на склад, где происходит "дозревание" материала.In the foam generator, foam is whipped from the mixture of the foaming agent with water. The mixing of all concrete components is carried out in a screw mixer, into which dry components are first fed: Portland cement and staple fiber, and then the prepared foam. From the mixer, the prepared mixture is evenly distributed over the area of metal forms pre-oiled with oil and fed to the heat-moisture treatment, which is carried out according to the regime of 3 + 9 + 3 hours at an isothermal holding temperature of 90 ° C. Then the finished product is removed from the molds and transported to a warehouse where the material “ripens”.
