Description
(54) БЕТОННАЯ СМЕСЬ(54) CONCRETE MIXTURE
Изобретение относитс к стройтел MiiM материалам и может быть испольэовано дл изготовлени бетонных и железобетонных элементов: плит до-рожных и аэродромных покрытий, пане лей ограждени , мостовых балок и т Известна бетонна смесь, включаю ща цемент, заполнитель, силиконат натри и воду Наиболее близкой по технической сущности и достигаемому результату к предлагаемой вл етс бетонна смесь 2, включающа цемент, песок кварцевый, щебень фр. 2,5-5 мм, полиэтилгидросилоксан и воду при следующем соотношении компонентов, Bec.Z: 15,3-16,0 Цемент 22,7-23,9 Песок кварцевый Щебень фр. 2,553 ,9-56,1 5,0 мм Полиэтилгидросил0 ,15-1,25 5,9-6,2 Недостаток указанных смеСей - низка морозостойкость и водонепроницаемость получаемого бетона. Цель изобретени - повышение морозостойкости и водонепронпцаекюсти бетона. доставленна цель достигаетс тем, что бетонна смесь, включающа цемент, заполнитель, кремнийорганическум добавку и воду, в качестве кремю органической добавки содержит мепштрибутоксисилан, при следушцеи соотношении компонентов масс.% Цемент20-50 Заполнитель 30-75 Метилтрибутоксисилан0 ,01-1,2 ВодаОстальное Метилтрибутоксисилан с формулой CHjS (0(Ьи)в водной среде бетонной смеси, имеющей щелочную реак1;ию , гидролизуетс и полимеризуетс по схеме i (0( ) ( CH)S ip2-p5) m C The invention relates to construction materials MiiM and can be used for the manufacture of concrete and reinforced concrete elements: road and airfield paving slabs, fencing panels, bridge beams, and t. A known concrete mixture including cement, aggregate, sodium silicate and water. the technical essence and the achieved result to the proposed is concrete mix 2, including cement, quartz sand, crushed stone FR. 2.5-5 mm, polyethylsiloxane and water in the following ratio of components, Bec.Z: 15.3-16.0 Cement 22.7-23.9 Sand quartz Crushed stone fr. 2,553, 9-56,1 5,0 mm Polyethylhydros0, 15-1,25 5,9-6,2 The disadvantage of these mixes is low frost resistance and water resistance of the resulting concrete. The purpose of the invention is to increase the frost resistance and water resistance of concrete. the delivered goal is achieved by the fact that a concrete mix, including cement, aggregate, silicone additive and water, contains meptributoxysilane as a cream for organic additive, with the following ratio of components by weight Cement 20-50 Filler 30-75 Methyltributoxysilane 0, 01-1.2 Water Total Met. with the formula CHjS (0 (bi) in an aqueous medium of a concrete mixture having an alkaline reaction; iy, it is hydrolyzed and polymerized according to the scheme i (0 () (CH) S ip2-p5) m C
