Concrete mix design laboratory tests which time consuming and entails considerable effort. This study presents a method of reducing mix design testing costs by testing mortar instead of concrete specimens. The experimental programme consisted of defining mortar mixes equivalent to concrete mixes, moulding specimens of both mortar and concrete mixes studied and finally evaluating the compressive strength of specimens cured at different curing time. Results obtained indicate that a good linear correlation between the compressive strength of mortar and the corresponding concrete exist. It is concluded that trial laboratory testing of mortar mixes may be used for prediction of corresponding concrete mixes.
