Abstract: The composition of fine-grained concrete with an organic-mineral modifier (OMM) based by agglomerated wetsilicafumefromtheStakhanovferroalloyplant, crushing limestone from the Dokuchaevsk flux-dolomite plant, and also with C-3 superplasticizer based on polycondensate of sulfonated naphthalene-formaldehydetothe concrete compressive strength at design age was optimizedby using a full three-factor experiment with variation levels of –1, 0, +1. The mix compositions of fine-grained concrete with the use of industrial waste from the Donbas characterized by a compressive strength of at least 30 MPa at design age have been developed.
Keywords: slump, crushing limestone, organic-mineral modifier, superplasticizer.
Pages: 46-52.
