Для оценки влияния комплексных добавок на реологические свойства бетонной смеси проводились испытания по ГОСТ 10180-90 «Бетоны. Методы определения прочности по контрольным образцам».To assess the effect of complex additives on the rheological properties of the concrete mixture, tests were performed according to GOST 10180-90 “Concretes. Methods for determining the strength of control samples. "

Испытания бетонной смеси следует проводить через 15 минут после отбора пробы по ГОСТ 27006-86 «Бетоны. Правила подбора состава». Результаты испытаний приведены в табл.1 и 2. Результаты проведенных испытаний показали положительную динамику по набору прочности в условиях твердения бетона при температуре до -25°С и раствора при температуре -20°С, бетонная смесь при отрицательной температуре порядка -18°С имеет высокую сохраняемость (через час после приготовления подвижность бетонной смеси осталась практически неизменной), бетонная и растворные смеси седиментационно устойчивы, и затвердевший бетон не имел расслоения растворной части.Testing the concrete mix should be carried out 15 minutes after sampling according to GOST 27006-86 “Concretes. Rules for the selection of the composition. " The test results are shown in Tables 1 and 2. The results of the tests showed positive dynamics in the set of strength under conditions of hardening of concrete at temperatures up to -25 ° C and mortar at -20 ° C, concrete mixture at a negative temperature of about -18 ° C high shelf life (an hour after preparation, the mobility of the concrete mixture remained virtually unchanged), concrete and mortar mixtures were sedimentation stable, and the hardened concrete did not have a stratification of the mortar part.
