Для приготовления сырьевой смеси дозируют сырьевые компоненты. Портландцемент, кварцевый песок, алюминиевую пудру, метасиликат натрия, синтетический ванилин смешивают. К смеси сухих компонентов добавляют нагретую до температуры 55-75°С воду, 1 н. раствор NaOH и еще раз смешивают. Приготовленную смесь равномерно распределяют по площади предварительно смазанных маслом и нагретых до 35-40°С металлических форм (заполняют формы примерно на 1/2 их объема), выдерживают в формах в течение 12-16 часов, затем отформованные изделия освобождают от форм, при необходимости разрезают на части и подают на автоклавную обработку, которую проводят при температуре 175°С и давлении 0,8 МПа. Общая продолжительность автоклавной обработки 10-12 часов. После выгрузки из автоклава изделия выдерживают в течение 2 часов в помещении с температурой не менее 18°С. Морозостойкость газобетона составит не менее 25 циклов.To prepare the raw mix, the raw materials are dosed. Portland cement, quartz sand, aluminum powder, sodium metasilicate, synthetic vanillin are mixed. To a mixture of dry components add water, heated to a temperature of 55-75 ° C, 1 N. NaOH solution and mixed again. The prepared mixture is evenly distributed over the area of metal molds pre-oiled and heated to 35-40 ° C (fill the molds by about 1/2 of their volume), kept in the molds for 12-16 hours, then the molded products are freed from the molds, if necessary cut into pieces and fed to the autoclave treatment, which is carried out at a temperature of 175 ° C and a pressure of 0.8 MPa. The total duration of autoclave treatment is 10-12 hours. After unloading from the autoclave, the products are kept for 2 hours in a room with a temperature of at least 18 ° C. Frost resistance of aerated concrete will be at least 25 cycles.
