Description
Изобретение касаетс способа получени ангидритового цемента путем совместного размола ангидрита или мертво обожженного гипса с добавками .The invention relates to a method for producing anhydrite cement by co-grinding anhydrite or deadly burnt gypsum with additives.
Автором насто щего изобретени установлено, что в качестве добавки к ангидриту может быть применена зола сланцев или жийкоудаленный, пробужденный шлак от их сжигани , или и то и другое вместе. При этом вместо ангидригга или мертво обожженного гипса может быть применен гипс двуводны.й или полуводный или эстри|х гипс.The author of the present invention has established that as an additive to anhydrite, shale ash or liquid-removed, awakened slag from burning them, or both can be used. In this case, instead of anhydriga or deadly burned gypsum, two-water or semi-aquatic or estri-x gypsum gypsum can be used.
в зависимости от хим1ического состава золы И.ПИ шлака количество их беретс примерно от 5 до 30 и; более процентов. Сопротивление сжатию через 28 дней достигает при этом до 150 и более кг/см.depending on the chemical composition of ash I.PI of slag, their number is taken from about 5 to 30 and; more percent. Resistance to compression after 28 days reaches up to 150 kg / cm or more.
Пробуждение активности шлаков может быть проведено путем обработки их паром под давлением, мокрым помолом с добавкой или без добавки извести или помолом сланцевой золы со шлаком тех же сланцев.The awakening of slag activity can be carried out by treating them with steam under pressure, wet grinding with or without the addition of lime or grinding shale ash with slag from the same shale.
