sl 1 Изобретение относитс к произвол ству строительных материалов и может быть использовано дл изготовл заполнител . НИН легкого Цель изобретени - снижение энер гозатрат и повьшение прочности бетона на разрыв. Сырьева смесь дл изготовлени легкого заполнител содержит перлитовую породу, оксид или гидроксид кальци , пьшеватые отходы производства перлита и полуводный сернокислый кальций при следующем соотношении компонентов, мае.%: Перлитова порода37-69 Оксид или гидр- оксид кальци 10-20 7 Пьшеватые отходы производства перлита 5-50 Полуводньй сернокисльш кальций3-6 Приготовление сырьевой смеси , сводитс к измельчению перлитовой породы до удельной поверхности 4000 , перемешиванию компонентов и гранул ции смеси на водном св - зующем. Полученные гранулы подвергают тепловлажностной обработке по известной технологии пропаривани при температуре изотермической вьщерж- ки 95-1ОО С в течение 8 ч. Примеры составов сьфьевой смеси и свойства полученных заполнителей представлены в табл. 1 и 2. Таблица 1sl 1 The invention relates to the arbitrariness of building materials and can be used to make a filler. Lung NIN The purpose of the invention is to reduce energy consumption and increase the tensile strength of concrete. Raw mixture for the manufacture of lightweight aggregate contains perlite rock, calcium oxide or hydroxide, pearl waste from the production of perlite and hemihydrate calcium sulphate in the following ratio of components, percent in May: Perlite rock37-69 Oxide or calcium hydroxide 10-20 7 Pearl from the production of pearlite 5-50 Semi-water calcium sulfate 3-6 Preparation of the raw mix is reduced to grinding perlite rock to a specific surface of 4000, mixing the components and granulating the mixture on a water binder. The obtained granules are subjected to heat-moisture treatment according to the known technology of steaming at an isothermal temperature of 95-1OO C for 8 hours. Examples of the composition of the mixture and the properties of the obtained aggregates are presented in Table. 1 and 2. Table 1
