Description

Изобретение относитс  к промышленности строительных материалов и может быть использовано при производстве строительных растворов и бетонов.The invention relates to the building materials industry and can be used in the production of mortars and concretes.

Цель изобретени  - повышение прочности бетона и снижение расхода цемента .The purpose of the invention is to increase the strength of concrete and reduce cement consumption.

Пример. Готов т 50%-ный водный раствор сульфитно-дрожжевой барды (СДБ), разбавл ют 50%-ный водный раствор СДБ, электролизной водой с рН 10 до концентрации 33-40%. Затем довод т концентрацию раствора СДБ до 8-10%. Дозируют в смеситель и перемешивают цемент, песок, щебень, водный раствор СДБ 8-10% нои концентрации и воду зат- ворени .Example. A 50% aqueous solution of sulphite-yeast stillage (BD) is prepared, a 50% aqueous solution of BD is diluted with electrolysis water with a pH of 10 to a concentration of 33-40%. Then, the concentration of the SDB solution is adjusted to 8-10%. The cement, sand, crushed stone, aqueous solution of SDB of 8–10% concentration and mixing water are metered into the mixer and mixed.

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