RELATIONSHIP BETWEEN ULTRASONIC PULSE VELOCITY AND COMPRESSIVE STRENGTH OF SELF COMPACTING CONCRETE INCORPORATE RICE HUSK ASH AND METAKAOLIN

The objective of the present investigation was to evaluate RHA and MK as supplementary cementitious materials (in both binary and ternary systems) in terms of harden properties in blended cement SCC and to identify the optimal level of replacement of ordinary Portland cement (OPC) with RHA, MK, or RHA+MK. The blended cements were prepared by replacing OPC with RHA, MK, or RHA+MK (5–40%) in dry conditions. In addition to that the interrelationship between harden properties such as compressive strength and ultrasonic pulse velocity was discussed.
