Description
Изобретение относитс к составам комплексных добавок дл бетонной смеси.This invention relates to compositions of complex additives for a concrete mix.
Цель изобретени - повышение водр- и морозостойкости бетона.The purpose of the invention is to increase the water and frost resistance of concrete.
Комплексную добавку ввод т в бетонную смесь в количестве 2-4% от массы цемента совместно с водой зат- ворени (табл.1).The complex additive is introduced into the concrete mix in the amount of 2-4% by weight of cement along with the mixing water (Table 1).
Добавку вводили в бетонную смесь состава пшакопортландцемент: песок: щебень 1:2:4 по массе при подвижности бетонной смеси 4 см.The additive was introduced into the concrete mix of the composition psákoportlandtsement: sand: crushed stone 1: 2: 4 by weight with the mobility of the concrete mix 4 cm.
Водостойкость бетона оценивали по коэффициентам водостойкости и разм гчени (Кр и Kg) на образцах- кубах с размером 15x15x15 см. Определение Кр и Квпроизводили после мес чного насыщени образцов водой в 28-сут очном возрасте бетона.The water resistance of concrete was evaluated by the coefficients of water resistance and softening (Kp and Kg) on samples-cubes with a size of 15x15x15 cm.
В табл.2 приведены результаты испытаний образцов из бетона с предлагаемой и известной комплексными добавками, а также без добавки,при- готовленной на галакопортландцементе и портландцементе, на водо- и моро- i зостойкость бетона.Table 2 shows the results of testing samples from concrete with the proposed and well-known complex additives, as well as without the additive prepared on galakoportlandtsement and portland cement, on the water and frost resistance of concrete.
