MECHANICAL PROPERTIES OF BINARY AND TERNARY BLENDED CONCRETE CONTAINING RICE HUSK ASH

This paper reports an investigation on the mechanical properties of Grade 40 concrete made with binary and ternary blends of normal Portland cement (NPC), rice husk ash (RHA) and fly ash (FA). Conventional superplasticizer was used to impart required workability. Five mixes (control superplasticized NPC, RHA and FA binary blend as well as two ternary (NPC/RHA/FA)) combinations were chosen for tests on mechanical properties. Data up to 180 days showed that inclusion of RHA in binary and ternary combination can provide the desired workability and enhancements in many mechanical properties compared to the control.
