Description

Изобретение относится к промышленности строительных материалов, а именно к составу сухой цементной смеси, предназначенной для получения водонепроницаемых бетонов и растворов, и может быть использовано в монолитном строительстве и для изготовления бетонных и железобетонных изделий и конструкций повышенной водонепроницаемости, не нуждающихся в дополнительной гидроизоляции. The invention relates to the construction materials industry, in particular to the composition of the dry cement mixture intended for the production of waterproof concrete and mortar, and can be used in monolithic construction and for the manufacture of concrete and reinforced concrete products and structures of increased waterproofness that do not need additional waterproofing.

Известна вяжуще-сухая смесь, содержащая, мас.%: вулканический пепел 65 - 82, строительный гипс 3,95 - 5,80, алкилкарбоксиэтаноламин 0,05 - 0,20, известь. (см. а.с. СССР N 1766859, C 48 B 7/00, 07.10.92). Known binder-dry mixture containing, wt.%: Volcanic ash 65 - 82, building gypsum 3.95 - 5.80, alkylcarboxyethanolamine 0.05 - 0.20, lime. (see A.S. USSR N 1766859, C 48 B 7/00, 10/07/92).

Наиболее близкой по технической сущности и достигаемому результату является сухая цементная смесь, содержащая портландцемент и минеральную расширяющуюся добавку в количестве 15 - 25% от массы цемента. Минеральная расширяющаяся добавка содержит (в мас.%) вулканическую породу 65 - 85, гипс 15 - 85, доломит 1 - 5, микрокремнезем 4 - 30. (см. патент РФ N 2085527, C 04 B 7/345, 27.07.97). The closest in technical essence and the achieved result is a dry cement mixture containing Portland cement and an expanding mineral additive in an amount of 15 - 25% by weight of cement. Mineral expanding additive contains (in wt.%) Volcanic rock 65 - 85, gypsum 15 - 85, dolomite 1 - 5, silica fume 4 - 30. (see RF patent N 2085527, C 04 B 7/345, 07.27.97) .

Задачей изобретения является получение как безусадочной, так и расширяющейся цементной смеси и повышение водонепроницаемости бетонов и растворов, изготовленных с применением этой смеси. The objective of the invention is to obtain both non-shrinking and expanding cement mixtures and increasing the water resistance of concrete and mortars made using this mixture.

Поставленная задача решается тем, что сухая цементная смесь, включающая портландцемент и минеральную расширяющуюся добавку, содержащую вулканическую породу, гипс, доломит и микрокремнезем, в качестве минеральной расширяющейся добавки содержит добавку "ИР-1", в составе которой используется вулканическая порода с соотношением оксид кремния:оксид алюминия более 3,5, содержащая пемзу 1 - 15 мас. %, и дополнительно в составе добавки содержится пластификатор при следующем соотношении компонентов добавки, мас.%: указанная вулканическая порода 40 - 85, гипс 10 - 35, доломит 0 - 30, микрокремнезем 0 - 5, пластификатор 1 - 3, при следующем соотношении компонентов сухой цементной смеси, мас.%: портландцемент 75 - 95, минеральная расширяющаяся добавка 5 - 25. The problem is solved in that a dry cement mixture, including Portland cement and a mineral expanding additive containing volcanic rock, gypsum, dolomite and silica fume, as a mineral expanding additive contains an additive "IR-1", which uses volcanic rock with a ratio of silicon oxide : aluminum oxide of more than 3.5, containing pumice 1 to 15 wt. %, and additionally, the additive contains a plasticizer in the following ratio of the components of the additive, wt.%: the specified volcanic rock 40 - 85, gypsum 10 - 35, dolomite 0 - 30, silica fume 0 - 5, plasticizer 1 - 3, in the following ratio of components dry cement mixture, wt.%: Portland cement 75 - 95, mineral expanding additive 5 - 25.

Причем смесь может содержать ускоритель твердения и/или замедлитель твердения, и/или гидрофобизатор, а также противоморозные добавки. Moreover, the mixture may contain a hardening accelerator and / or hardening inhibitor, and / or water repellent, as well as anti-frost additives.

Для приготовления сухой цементной смеси используют следующие материалы: портландцемент М-400 и добавку "ИР-1", содержащую вулканическую породу с соотношением оксид кремния:оксид алюминия более 3,5, содержащую 1 - 15% пемзы, гипс, кремнезем ТУ 7-249533-01-90 и пластификатор C-3 ТУ 6-36-02-04-229-625-30. The following materials are used to prepare a dry cement mixture: Portland cement M-400 and an additive "IR-1" containing volcanic rock with a ratio of silicon oxide: aluminum oxide of more than 3.5, containing 1-15% pumice, gypsum, silica TU 7-249533 -01-90 and plasticizer C-3 TU 6-36-02-04-229-625-30.

Компоненты добавки мелят совместно до удельной поверхности 3000-7000 см2/г. Полученную добавку смешивают с цементом.The components of the additive are grinded together to a specific surface of 3000-7000 cm 2 / g. The resulting additive is mixed with cement.

Для испытания сухой цементной смеси готовили образцы размером 4х4х16 см, затворяя ее водой, в соотношении В/Ц=0,4-0,5. To test the dry cement mixture, samples of 4x4x16 cm in size were prepared by shutting it with water in the ratio W / C = 0.4-0.5.

Примеры составов смеси и их свойства приведены в таблицах 1 и 2. Examples of mixtures and their properties are shown in tables 1 and 2.

Как видно из приведенных данных сухая цементная смесь "ПРОГРЕСС-1" может быть получена как безусадочной, так и расширяющейся и имеет повышенную водонепроницаемость и морозостойкость. As can be seen from the above data, the dry cement mixture "PROGRESS-1" can be obtained both non-shrinking and expanding and has increased water resistance and frost resistance.
