Abstract
Description
Изобретение относится к промышленности строительных материалов, в частности к производству ячеистых бетонов, используемых в малоэтажном строительстве.The invention relates to the building materials industry, in particular to the production of cellular concrete used in low-rise construction.
Известна смесь для изготовления газобетона, включающая портландцемент, кварцевый песок, алюминиевую пудру, воду [1].A known mixture for the manufacture of aerated concrete, including Portland cement, quartz sand, aluminum powder, water [1].
Задача изобретения - упрощение технологии приготовления газобетона, повышение его морозостойкости.The objective of the invention is to simplify the technology of preparation of aerated concrete, increasing its frost resistance.
Технический результат достигается тем, что сырьевая смесь для изготовления газобетона, включающая портландцемент, кварцевый песок, алюминиевую пудру, воду, дополнительно содержит метасиликат натрия, 1 н. раствор NaOH, синтетический ванилин при следующем соотношении компонентов, вес.ч: портландцемент 270-290; кварцевый песок 270-290; алюминиевая пудра 2-2,5; вода с температурой 55-75°С 180-220; метасиликат натрия 0,1-0,15; 1 н раствор NaOH 1-1,5; синтетический ванилин 0,01-0,03.The technical result is achieved in that the raw material mixture for the manufacture of aerated concrete, including Portland cement, quartz sand, aluminum powder, water, additionally contains sodium metasilicate, 1 N. NaOH solution, synthetic vanillin in the following ratio of components, parts by weight: Portland cement 270-290; silica sand 270-290; aluminum powder 2-2.5; water with a temperature of 55-75 ° C 180-220; sodium metasilicate 0.1-0.15; 1 n NaOH solution 1-1.5; synthetic vanillin 0.01-0.03.
Составы сырьевой смеси приведены в таблице.The composition of the raw mix is shown in the table.
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.
