Abstract

The paper investigates the production of self-compacting concrete (SCC) more affordable for construction industry with various percentages of fly ash as part of the total powder content and bottom ash as replacement of fine aggregates. Various properties studied included strength (compressive and split tensile strength) and durability properties (carbonation and deicing salt surface scaling). Based on the materials used in this study, the SCC was observed to be flowable, cohesive, and developed 28-day compressive strength, approximately in the range of 18–35 MPa. Besides the environmental benefits, there could be some technical and economical advantages as well. As a general result, presence of fly ash and bottom ash affected the durability properties of concrete positively.
