Description
Изобретение относитс к технологии строительных материалов и может быть использовано при изготовлении бетонных и железобетонных изделий дл промышленного и гражданского строи- тельствааThe invention relates to the technology of building materials and can be used in the manufacture of concrete and reinforced concrete products for industrial and civil construction.
Цель изобретени - повышение прочности бетонных изделий и снижение их себестоимости.,The purpose of the invention is to increase the strength of concrete products and reduce their cost.
Ангидритосодержащий компонент, вл ющийс отходом производства пла- иико ой кислоты, имеет состав, мас.%: CaS04 74-92; НгП04 10-15; HF 1-3; соли АД, Fe, Na, К, Mf, GiO 2-10. Плотность 7,45 г/см Бокситовый шлам имеет состав, м сД: А1203 13- 38; (3 42,8; 8; СаО 14,86; п.п.п 20,5, vn нов. 3500-5000 смг/г.The anhydrite-containing component, which is a waste product of the production of plastic acid, has a composition, wt%: CaS04 74-92; NgP04 10-15; HF 1-3; salts AD, Fe, Na, K, Mf, GiO 2-10. Density of 7.45 g / cm Bauxite slurry has a composition, m sd: A1203 13-38; (3 42.8; 8; CaO 14.86; ppt 20.5, vn new. 3500-5000 cmg / g.
Смесь готов т следующим образом. Ангидритосодержащий компонент (отход производства плавиковой кислоты), цемент, песок, супьфитно-спиртовую барду, бокситовый шлам и мраморную крошку перемешивают вручную в течение 2-3 мин, затем смесь помещают в бетономешалку , затвор ют водой и перемешивают в течение 5-10 мин. Полученную бетонную смесь из бетономешалок заливают в формы кубов с гранью 10, 15, 20 см и призм - см, и выдерживают в пропарочных камерах по режиму 2+3 + 8+2; 2+5+7 + 9; 3+5+8+4; 4+5+7 + 9 ч , а также до 28- I 80 сут нормального твердени , а татом в воздутано-су- хих услови х до распалубки в течение 3- 4 ч.The mixture is prepared as follows. The anhydrite-containing component (hydrofluoric acid production waste), cement, sand, sugary alcohol bard, bauxite sludge and marble chips are mixed by hand for 2-3 minutes, then the mixture is placed in a concrete mixer, sealed with water and mixed for 5-10 minutes The resulting concrete mix of concrete mixers is poured into forms of cubes with a facet of 10, 15, 20 cm and prisms - cm, and kept in steaming chambers according to the mode 2 + 3 + 8 + 2; 2 + 5 + 7 + 9; 3 + 5 + 8 + 4; 4 + 5 + 7 + 9 hours, as well as up to 28- I 80 days of normal curing, and a tatom in air-dry conditions before stripping for 3-4 hours.
