Abstract
The present disclosure describes a self-consolidating concrete (SCC) mixture having a compressive strength of at least 25 MPa at 28 days of age. In accordance with one embodiment, there is provided an SCC mixture, comprising: a mixture of coarse aggregate (CA), fine aggregate (FA), very fine aggregate (VFA), cementitious materials including Portland cement or Portland limestone cement, an ASTM C494 Type F polycarboxylate ether high range water reducer, and water, wherein the VFA has a particle size distribution in which 95% to 100% passes a 2.5 mm sieve and in which 20% to 100% passes a 75 μm sieve.
