Abstract: The uncertain supply of Fly-ash and relatively high cost of Slag as Supplementary Cementitious
Materials (SCMs) has become a concern to the concrete industry in the USA. Fly-ash is a
byproduct from coal burning plants which are shutting down or converting to natural gas, and
Slag is a residue from steel production mainly outside of the USA. This study focuses on the
evaluation of self-consolidating concrete (SCC) for a high-rise building using recycled post-
consumer glass, for 35% Glass-SCM cement replacement and 55 and 70 MPa strengths, to
compare with a similar SCC mix with Slag. The field work involved evaluations of mix
production, pump-ability, placement, finishing, curing, compressive and tensile strengths, and
development of maturity curves from data loggers in concrete. This study offers great potential
for benefitting the concrete and glass recycling industries.
