Abstract
Изобретение относитс к строительству , к технологии производства цементных бетонов и растворов и направлено на снижение в зкости и повышение прочности. Способ активации включает интенсивное механическое воздействие в течение 0,5-5,5 мин, введение СДБ в количестве 0,1-0,5% в момент достижени наибольшего разжижени активируемого раствора с последующим механическим воздействием в течение 0,5-1,0 мин. 1 з.п.ф-лы, 2 табл.The invention relates to construction, to the production technology of cement concrete and mortars, and is aimed at reducing viscosity and increasing strength. The activation method includes an intense mechanical effect for 0.5–5.5 min, the introduction of an RR in an amount of 0.1–0.5% at the time of the greatest dilution of the activated solution, followed by a mechanical effect for 0.5–1.0 min . 1 hp ff, 2 tab.
Description
Изобретение относитс к строительству , к технологии производства цементных растворов и бетонов.The invention relates to the construction, production technology of cement mortars and concretes.
Цель изобретени - снижение в зкости и повышение прочности.The purpose of the invention is to reduce viscosity and increase strength.
Пример. Готов т цементный раствор смешением портландцемента и воды. Водо- цементное отношение 0,3-0,8.Example. Cement mortar is prepared by mixing Portland cement and water. Water-cement ratio 0.3-0.8.
Цементный раствор активируют механическим воздействием в турбулентном смесителе в течение С,,5 мин. При достижении максимального разжижени цементного раствора ввод т0,1-0,5% СДБ. Затем цементный раствор с добавкой активируют в турбулентном смесителе в течение 0,5-1,0 мин.The cement slurry is activated by mechanical action in a turbulent mixer for C ,, 5 minutes. When the maximum dilution of the cement slurry is reached, a 0.1-0.5% SDB is added. Then the cement slurry with the additive is activated in a turbulent mixer for 0.5-1.0 minutes.
Результаты испытаний представлены в табл. 1 и 2.The test results are presented in Table. 1 and 2.
