Description
Изобретение относитс к изготовленнию силикатобетонных изделий.The invention relates to the manufacture of silicate concrete products.
Известен способ изготовлени силикатобетонных иЭделий путем пере- J мешивани исходных компонентов,. выдержива до момента достижен и максимальной температуры силикатобетонной смеси за счет тепла, выдел емого при гидратации окиси кальцййГ, fg повторного перемешивани схватившейс смеси с последующей укладкой в форму, уплотнением и термообработкой 1.A known method for the manufacture of silicate concrete and components by mixing the initial components ,. keeping up to the moment the maximum temperature of the silicate-concrete mixture is reached due to the heat released during the hydration of calcium hydroxide, fg re-mixing of the seized mixture followed by packing into a mold, compaction and heat treatment 1.
Известен также дезинтеграторный jj способ изготовлени издеЛйЙ путём смешени молотой негашеной извести, песка, добавок и воды с последующим формованием и термообработкрй, который вл етс наиболее близким к 20 предлагаемому 2j.Also known is the disintegrator jj method of making a product by mixing ground quick lime, sand, additives, and water, followed by molding and heat treatment, which is closest to 20 of the proposed 2j.
Недостатками известного способа вл етс недостаточно высока ttpOiность и морозостойкость изделий.The disadvantages of this method are not high enough ttpOinost and frost resistance of products.
Цель изобретени - улучшение 25 качества, повышение прочности и морозостойкости изделий из плотного силикальцитного бетона.The purpose of the invention is to improve the quality, increase the strength and frost resistance of products made of dense silica silicate concrete.
Это достигаетс тем, что в способе изготовлени автоклавных изделий путем смешени Мблотой негашеной извести , песка, добавок и воды в дезийтеграторе с последующим формованием и термообработкой смешивают сначала в дезинтеграторе 30-65% песка и столько же извести с водой, нагретой от 20 до 85 С, полученную смесь с влШноетьго 22-25% вьщерживают 30-40 мин и затем смешивают ее с оставшейс частью сухого песка и извести в смесителе принудительного действи и потс л формуют изделие при влажности смеси 6-7% и температуре 60-65 С. При этом дл замедлени скорости гашени в смеситель .. принудительного действи дополнительно ввод т добавку известкового теста ..This is achieved by the fact that in the method of manufacturing autoclaved products by mixing a lot of quicklime, sand, additives and water in a disintegrator followed by molding and heat treatment, 30-65% of sand and the same lime with water heated from 20 to 85 ° C are mixed. , the resulting mixture with a 22-25% weight is held for 30-40 min and then mixed with the remaining part of dry sand and lime in a forced-action mixer and then the product is molded at a moisture content of 6-7% and a temperature of 60-65 C. to slow down sk blanking grow in a forced action mixer .. additionally introduced additive lime paste ..
Влажность формовочной массы выдерживают порйдка 6-7%, а температуру бетона, уложенного в формах, не более 65с. Воду подают только в первсм приготовлени бетона в ДёЗйнтёгратбр е дл йёдлённЬ гас щейс извести воду подогревают до температуры 80-85с. В результате применени способа приготовлени плотного бетона прочность силикальцйткцх изделий повышаетс в 2-4 раза , морозсх;тойкость в 4-8 раз.Humidity of the molding material can withstand a flow of 6-7%, and the temperature of the concrete laid in the forms, not more than 65s. Water is supplied only in the first concrete preparation of the déointergrowth for dry lime water is heated to a temperature of 80-85 s. As a result of applying the method of preparing dense concrete, the strength of silica products increases by 2-4 times, with frost, and the strength by 4-8 times.
Одновременио улучшаютс и другие физико-механические свойства.At the same time, other physicomechanical properties are improved.
. Пример. Изготовление изделий йэ плотного высокопрочного с или к§.Йьцнтного бетона на основе молотой негаиеной извести - кипелки, песка и добавок осуществл ют вдва. приема с последующим формованием и.термообработкой изделий в автоклавах . ,. Example. The manufacture of products of high-strength, high-strength c or c. Light concrete based on ground unhygienic lime — boilers, sand, and additives is carried out twice. reception with the subsequent molding and thermal processing of products in autoclaves. ,
