Изобретепиг - но ситс к технологии проиводства местнь. строительных материалов и может быть использовано дл замедлени скорости Гидратации минеральных в жущих.Invention - but the situation with the technology of production is local. building materials and can be used to slow down the rate of hydration of mineral in the eater.
Известен способ гашени извести, заключающийс iB затворениИ ее водой ic одновременным введением добавки.There is a known method of slaking lime, which consists of mixing iB with water and ic by the simultaneous introduction of an additive.
Недостатком такого способа вл етс снижение прочности из1вестково-песча;ных изд..лий при ее применении.The disadvantage of this method is the reduction of the strength of the sandy sands.
Целью изобретени вл етс замедление процесса гидратации извести и ловыщение прочности силикатных изделий на ее основе.The aim of the invention is to slow down the process of hydration of lime and to increase the strength of silicate products based on it.
Это достигаетс тем, что IB качестве добазки ВВОДЯТ молочную сыворотку В Количестве 2-4% от веса извести.This is achieved by the fact that IB as an admixture injects whey in an amount of 2-4% by weight of lime.
Так, например, если скорость гащени извести .по известному способу (Определ ема по стапдартной методи1ке) составл ет 30 мин, то 1C добавкой 2% сыворотки она увеличиБаетс до 70 мин и при добавке 4% вдолочиой сЫВоротки - до 120 мин. При этом температура смеси, развИвающа с при гашении, снижаетс в 5-7 раз по сравнению с обычным способом гашени .So, for example, if the lime reduction rate is 30 minutes by the known method (Determined by the standard method), then 1C with 2% serum it increases to 70 minutes and with 4% added in the milk column, up to 120 minutes. At the same time, the temperature of the mixture, which develops during quenching, is reduced by 5-7 times as compared with the usual quenching method.
Молочна сыворотка В меньшей степени снижает .прочность авто-клавных изделий наDairy serum To a lesser extent, reduces the strength of auto-clavs on

основе пзвести, примен емые IB Насто. врем органические добавки, в частност.:, сульфитно-сннртова барда п др. Так прочность известково-песчаных образцов, получе.нных на основе пзвестп, гаС щейс без введени добавок, составл ет после их автоклавной обработки 120 кг/см, а при введении в процессе гашени 1% сульфитно-спиртовой барды она снижаетс до 52 кг/см, а при iBBiдепии 2% или 4% молочной сыворотки прочность образцов соста вл ет 115 и 100 кг/см соответственно.Based on the list, apply IB nasto. The time organic additives, in particular., sulphite-snarr bard n others. Thus, the strength of lime-sand samples obtained on the basis of a sandstone gas without additives was 120 kg / cm after their autoclave treatment, and in the process of quenching of 1% sulfite-alcohol stillage, it decreases to 52 kg / cm, and at iBBi depy of 2% or 4% whey, the strength of the samples is 115 and 100 kg / cm, respectively.
Преимуществом применени молочиой сыворотки вл етс ее дешевизна и доступность , так как она вл етс отходом При производстве молочных продуктов.The advantage of using dairy whey is its low cost and availability, since it is a waste in the production of dairy products.
