Description
Насто щее изобретение касаетс упрощенного способа получени расшир ющегос цемента.The present invention relates to a simplified method for producing expandable cement.
Сущность предлагаемого способа заключаетс в следующем. Каолин или глина обжигаетс при температуре 700-800°, после чего измельчаетс до прохождени через сито в 900 отв/см без остатка. К измельченному каолину или глине добавл етс известь совместно с портланд-цементом (или без последнего) в следующей примерно пропорции (в%):, ,The essence of the proposed method is as follows. The kaolin or clay is burned at a temperature of 700-800 °, after which it is crushed to pass through a sieve of 900 holes / cm without a residue. Lime is added to ground crushed kaolin or clay together with Portland cement (or without the latter) in the following approximate proportion (in%) :,

Тесна смесь указанных компонентов затвор етс 70% воды по весу и оставл етс твердеть в услови х воздушного или водного хранени в течение 7-15 суток. Затвердевший и высушенный цемент измельчаетс и смешиваетс с полуводным гипсом в пропорции: 50% полуводного гипса и 50% затвердевшего и измельченного цемента указанного выше состава .The tight mixture of these components closes 70% of the water by weight and is allowed to harden under air or water storage for 7-15 days. Hardened and dried cement is ground and mixed with semi-aquatic gypsum in a proportion: 50% semi-aquatic gypsum and 50% hardened and crushed cement of the above composition.

Полученна смесь (расшир юща с добавка) добавл етс к портландцементу (1 : 3 с песком) или другому гидравлическому в жущему в количестве от 5 до 15% от общего веса. Целесообразно при этом к воде затворени или к цементу добавл ть 1-2% CaCla от веса цемента. Степень расширени цемента колеблетс в пределах от 0,05 до 0,7% через . 7 суток с момента погружени образца в воду.The resulting mixture (expanding additive) is added to Portland cement (1: 3 with sand) or another hydraulic mixture in an amount ranging from 5 to 15% of the total weight. At the same time, it is advisable to add 1-2% of CaCla to the weight of the cement to the water of the cement or to the cement. The degree of cement expansion ranges from 0.05 to 0.7% through. 7 days from the moment the sample is immersed in water.
