Abstract FIELD: construction. ^ SUBSTANCE: complex additive for portland cement contains the following components, wt %: gypsum or anhydrite 30- 54, superplasticiser C-3 0.5-4.5, blast furnace dust 10-25, ash and slag wastes with content of aluminium oxide of at least 25 wt % 16.5-52.5, carbonate rock 12-35. ^ EFFECT: increased extent of expansion of portland cement, having higher hydraulic activity, reduced porosity of concrete at portland cement with the specified additive. ^ 3 tbl Изобретение относится к составу комплексной добавки для портландцемента. Комплексная добавка для портландцемента содержит, мас.%: гипс или ангидрит 30-54, суперпластификатор С-3 0,5-4,5, колошниковую пыль 10-25, золошлаковые отходы с содержанием оксида алюминия не менее 25 мас.% 16,5-52,5, карбонатную горную породу 12-35. Технический результат - увеличение степени расширения портландцемента, обладающего повышенной гидравлической активностью, снижение пористости бетона на портландцементе с указанной добавкой. 3 табл.
