SELF-CONSOLIDATING CONCRETE (SCC) MIXTURE HAVING A COMPRESSIVE STRENGTH OF AT LEAST 25 MPA AT 28 DAYS OF AGE

摘要

The present disclosure describes a self-consolidating concrete (SCC) mixturehaving a compressive strength of at least 25 MPa at 28 days of age. Inaccordancewith one embodiment, there is provided an SCC mixture, comprising: a mixtureofcoarse aggregate (CA), fine aggregate (FA), very fine aggregate (VFA),Portlandcement or Portland limestone cement, an ASTM C494 Type F polycarboxylate etherhigh range water reducer, and water, wherein the VFA has a particle sizedistribution in which 95% to 100% passes a 2.5 mm sieve and in which 20% to100% passes a 75 µm sieve.
