Abstract: The partial replacement of rice husk ash by cement in engineered cementitious composites had been reported to improve the properties of ECC especially its strength and extent of durability. There were no direct relation between the results of NDT in existing concrete structures. This article explores the relation between compressive strength of engineered cementitious composites and ultrasonic pulse velocity (direct and semi direct) method of hardened specimens. An experimental investigation was carried out which includes both destructive and nondestructive testing methods applied for ECC specimens containing rice husk ash and polypropylene fibres. Cubes of size 150mm * 150mm * 150mm are chosen for evaluation. Based on the outcome, relationships were derived for compressive strength and ultrasonic pulse velocity.
