Abstract
Изобретение относитс к строительным материалам, в частности к составам комплексных добавок, используемых в производстве бетонных изделий. Цель изобретени - повышение прочности бетона. Комплексна добавка дл бетонной смеси включает, мас.%: последрожжевой отход производства кормовых дрожжей со стадии сепарации на основе сырого протеина 9-30; сульфат натри 70-91. Прочность бетона с использованием добавки в количестве 1,8% от массы цемента - 39,8 МПа, 1 табл.The invention relates to building materials, in particular to the compositions of complex additives used in the manufacture of concrete products. The purpose of the invention is to increase the strength of concrete. The complex additive for concrete mix includes, in wt.%: The post-yeast feed production of fodder yeast from the separation stage based on crude protein 9-30; sodium sulfate 70-91. The strength of concrete with the use of additives in the amount of 1.8% by weight of cement - 39.8 MPa, 1 table.
