Description

Изобретение относитс  к способу приготовлени  бетошюй или растворной смеси и может найти применение в промьшшенности строительных материалов .The invention relates to a method for the preparation of betoshui or mortar mixtures and may find application in the construction materials industry.

Цель изобретени  - повышение подвижности смеси и прочности.The purpose of the invention is to increase the mobility of the mixture and strength.

Пример. Мелкий заполнитель увлажн ют до 8-20%-ной влажности вод ными растворами сульфитно-дрожжевой бражки или хлористого натри , затем обрабатывают его в металлической чаше электростатическим потенциалом 725 кВ (посто нное электрическое поле) g тем, что, с целью повышени  подвижв течение 1-2 мин и смешивают с остальными компонентами бетонной смеси. Из смеси готов т образцы-кубы с ребром 100tмм. Образцы пропаривают по режиму 3+6+3 ч при 80 С и через сутки испытывают.Example. The fine aggregate is moistened to 8–20% moisture with aqueous solutions of sulphite-yeast brewing or sodium chloride, then it is treated in a metal bowl with an electrostatic potential of 725 kV (constant electric field) g so that -2 min and mixed with the remaining components of the concrete mix. Cube samples with an edge of 100 mm are prepared from the mixture. Samples are steamed in the mode of 3 + 6 + 3 hours at 80 ° C and tested every other day.
