Description

Изобретение относитс  к составам бетонной смеси и может быть использовано при изготовлении бетонных и железобетонных изделий методом центрифугировани .The invention relates to concrete mixtures and can be used in the manufacture of concrete and reinforced concrete products by centrifuging.

Цель изобретени  - уменьшение усадки и набухани .The purpose of the invention is to reduce shrinkage and swelling.

Пример. Бетонную смесь готов т путем смешени  цемента, отходов асбестоцементного производства, песка кварцевого с модулем крупности ,6, гранитного щебн  фракции 2,5-20 мм и воды. Приготовленную смесь,формуют центрифугированием. Твердение колец осуществл ют в пропарочной камере по режиму 3+9+3 ч при температуре изотермической вьщержки . Из пропаренных бетонных колеД выпиливают образцы-кубы с ребром 0,06 м и образцы-балочки размером 0,06x0,06x0,24 м, которые твердеют в нормальных услови х в течение 27 сут. Затем образцы испытывают по ГОСТу 10060-76.Example. The concrete mix is prepared by mixing cement, asbestos-cement waste, silica sand with a grain size module, 6, 2.5-20 mm granite rubble and water. The mixture is molded by centrifugation. Hardening of the rings is carried out in a steaming chamber according to the 3 + 9 + 3 h mode at an isothermal temperature. Samples of cubes with an edge of 0.06 m and specimens of beams with a size of 0.06x0.06x0.24 m, which harden under normal conditions for 27 days, are cut from the steamed concrete walls. Then the samples are tested according to GOST 10060-76.

Результаты испытаний представлены в таблице.The test results are presented in the table.

Как следует из таблицы, бетонна  смесь по изобретению позйол ет полу- чать прочный морозостойкий бетон с пониженными усадкой и набуханием.As follows from the table, the concrete mix according to the invention allows to obtain strong frost-resistant concrete with reduced shrinkage and swelling.
