Abstract

Изобретение относится к области строительства, а именно к составу комплексной добавки для бетона, и может применяться при производстве бетонных и железобетонных изделий и конструкций и в монолитном строительстве. Задачами настоящего изобретения являются ускорение набора прочности на ранней стадии твердения и обеспечение высокой конечной прочности бетона при меньшем количестве вводимой добавки и сопутствующем упрощении процесса приготовления бетона. Комплексная добавка для ускорения твердения бетона, включающая суперпластификатор, в которую дополнительно введены ультрадисперсный микрокремнезем (УДМК), сульфат натрия и сульфат алюминия, при следующем соотношении компонентов, мас.%: ультрадисперсный микрокремнезем - 40-60, суперпластификатор - 20-30, сульфат натрия - 15-20, сульфат алюминия - 5-10.The invention relates to the field of construction, and in particular to the composition of a complex additive for concrete, and can be used in the production of concrete and reinforced concrete products and structures and in monolithic construction. The objectives of the present invention are to accelerate the set of strength at an early stage of hardening and to ensure high final strength of concrete with less input additives and the accompanying simplification of the concrete preparation process. A comprehensive additive to accelerate hardening of concrete, including a superplasticizer, in which ultrafine silica fume (UDMK), sodium sulfate and aluminum sulfate are additionally added, in the following ratio, wt.%: Ultrafine silica fume - 40-60, superplasticizer - 20-30, sodium sulfate - 15-20, aluminum sulfate - 5-10.
