Алюминатные цементы для ремонта гидротехнических сооружений

Abstract

RU: Выполнен анализ материалов, пригодных для ремонта подводных частей гидротехнических сооружений. В результате этого анализа, а также экспериментальных исследований влияния модифицирующих добавок на сроки схватывания, для разработки ремонтных композитов выбрали глиноземистый цемент.

EN: Hydraulic engineering constructions counteract the pressure of the water. The analysis of materials suitable for the reconstruction of their underwater parts has been made. There are a lot of composites and methods, but before using them we must take measures for dewatering an affected part of the construction. As a result of this analysis, as well as experimental researches aimed on how modifying additives influence on the setting time, we have chosen an aluminous cement as a base for repair composites that we would like to invent. Aluminous cement is well known quick hardening cement, but at the same time the hardening processes is not fast enough in the conditions of significant filtration. Regulation of setting time can be made by addition of a Са(ОН)2 and С3А.
