Abstract
The purpose of this study was to evaluate the effects of fly-ash and blast-furnace slag on strength development and durability of ternary blended concrete (TBC) and ordinary portland cement concrete as fly ash and slag contents. Main experimental variables were performed fly ash contents (0%, 10%) and slag contents (0%, 10%, 20%, 30%). The compressive and flexural strengths, chloride-ion rapid permeability and chemical attacks resistance were measured to analyze the characteristic of the developed TBC on hardened concrete. The test results showed that compressive and flexural strength of TBC increased as the slag contents increased from 0% to 30% at the long term of curing. It considers blast furnace slag used when fly ash content was up to 10%. The permeability resistance of TBC(fly ash 10%, blast 30%) was extremely good at the curing time 90 days. Also, the effects of added blast furnace slag on OPC and TBC were increased on the permeability and chemical attacks resistance.
