Description
Основным авт. св. 93230 защищен способ изготовлени сульфатоалюминатного цемента, отличающийс тем, что глину обрабатывают серной кислотой с целью получени аморфной кислоты и сернокислого аммони и полученные продукты смешивают с известью и гинсом дл получени сухой цементиоГ смеси гидросиликата и схмьфатоалюмината кальци .The main author. St. 93230 is a protected method for the manufacture of sulphate-aluminate cement, characterized in that the clay is treated with sulfuric acid to produce amorphous acid and ammonium sulphate and the resulting products are mixed with lime and gins to obtain a dry cement mixture of hydrosilicate and calcium cryptoaluminate.
Одиако при недостаточном количестве серной кислоты глина разлагаетс неполностью. Остаточна , неразложивша с глина набзхает в воде, отчего понижаетс водоустойчивость получаемого цемента.With an insufficient amount of sulfuric acid, clay does not fully decompose. The residual, undigested clay naps in the water, which reduces the water resistance of the resulting cement.
Дл устранени подобных влений предлагаетс глину неред ее обработкой серной кислотой обжигать при температуре 450-700 Можно также вместо обожженной глины приме}1 ть тонкоизмельче)иые материалы, содержащие обожженную глину, например горетые породы, шлаки и т. п. Во всем остальном споеоб ничем не отличаетс от способа, описанного в осliOBHOM авт. СЕ. N° 93230.To eliminate such phenomena, it is proposed to use clay with sulfuric acid treatment at a temperature of 450-700. Alternatively, instead of baked clay, fine materials can be used that contain baked clay, for example, burning rocks, slags, etc. In all other respects nothing does not differ from the method described in osliOBHOM ed. CE N ° 93230.
