RAW MATERIAL MIXTURE FOR MANUFACTURING FINE-GRAINED CONCRETE

摘要

FIELD: chemistry.SUBSTANCE: invention relates to industry of construction materials, in particular to production of fine-grained concretes. Raw material mixture for production of fine-grained concrete contains, wt %: Portland cement 26.0-28.0; ash after burning lignite/coal 57.16-61.0; sodium methylsiliconate 0.1-0.14; superplasticiser C-3 0.7-0.9; grinded to passing through No 014 mesh quartz sand 12.0-14.0; with water-cement ratio 0.4-0.45.EFFECT: reduction of cement consumption in composition of raw material mixture for production of fine-grained concrete.1 tbl
