ABSTRACT |
Influence of addition of by-pass dust(BD) to ordinary Portland cement(OPC) and blended cement systems on the hydration and mechanical properties of the cements was investigated. BD content increment in OPC and blended cement systems shortened induction period. In each curing time both OPC and slag cement systems showed their maximum value of compressive strength and bound water content at 5wt% of BD addition. As curing time passes by while the content of Ca(OH)2 in OPC increased that of blended cement decreased. From XRD results the peak of Friedel's salt(C3A |
