Description

Изобретение относитс  к проышленности строительных материаов и может быть использовано заодами , изгставлиБающ11ми огнепорные фосфатные издели .The invention relates to the industry of building materials and can be used by wells, exhausted phosphorous products.

Известен способ приготовлени  наполнител  дл  бетонов путем измельчени  материалов, используетлых как наполнители.There is a known method of preparing a filler for concrete by grinding materials used as fillers.

Недостаток известного способа заштючаетс  в том, что в процессе измельчени  материал обогащаетс  дисперсным металлом от мельниц, мел ющих тел и т.п. Дисперсный металл, содержащийс  в наполнителе , приводит к газовыделению при смешивании наполнител  с фосфатной св зкой или с ортофосфорной кислотой и к вспучиванию бетона, а это не всегда желательно.A disadvantage of the known method is that the material is enriched in the grinding process by dispersed metal from mills, grinding media, and the like. The dispersed metal contained in the filler leads to gas evolution when the filler is mixed with a phosphate binder or with phosphoric acid and to swell the concrete, and this is not always desirable.

Целью изобретени   вл етс  уменьшение содержа.ни  в наполнителе дисперсного металла и предотвращение за счет этого вспучивани  бетона, дл  чего измельченный наполнитель oбpaбaтывajoт перекисью водородаоThe aim of the invention is to reduce the content of the dispersed metal in the filler and thereby prevent the expansion of concrete, for which the crushed filler of the treatment with hydrogen peroxide

Предложенный способ осуществл етс  следующим образом.The proposed method is carried out as follows.

Полученныг путем измельчени  (поглола, дроблени ) наполнитель обрабатывают жидкостью, не взаимодействующей с наполнителем, но окисл ющей металл. Такой жидкостьюObtained by grinding (chopping, grinding) the filler is treated with a liquid that does not interact with the filler, but oxidizes the metal. Such a liquid

может служить перекись водорода, Молотый наполнитель увлажн ют окисл ющей жидкостью в количестве, определ емом опытным путем, в зависимости от вида жидкости и содержани  металла, а после этого выдерживают на складе до окончани  взаимодействи  и высыхани  наполнител .hydrogen peroxide can be used; the ground filler is moistened with an oxidizing fluid in an amount determined experimentally, depending on the type of liquid and the metal content, and then kept in stock until the end of the interaction and drying of the filler.

ПРадшТ ИЗОБРЕТЕ1МЯ Способ приготовлени  наполнител  дл  фосфатных бетонов, заключающийс  в измельчании алюмосодержащего сырь , например шлака, отличающийс  тем, что, с целью вспучивани  бетона путем уменыпени The method of preparation of the filler for phosphate concretes, which consists in grinding an aluminum-containing raw material, such as slag, characterized in that, in order to expand the concrete by reducing
