Abstract:The development of fly ash based high-strength self-compacting (or self-consolidating) concrete is a positive contribution to sustainable concrete technology. The present work details a mixture proportioning methodology for such concretes based on four steps where simple test procedures are used. Self-compacting concrete with a 90-day compressive strength of about 100 MPa has been obtained. This concrete has been used satisfactorily in a demonstration project involving the manufacture of a prefabricated urban bench with a complex shape. Such applications are promising since they lead to a reduction in energy and labor requirements during the casting and surface finishing, and facilitate the use of complex designs, while improving the factory environment through noise and vibration reduction.
