Non-destructive strength comparative analysis was carried out on water cured and air cured concrete cube samples. The investigation was for a period of 7, 14, 21 and 28 days. The concrete cube samples were designed using a mix ratio of 1:2:4 and water cement ratio of 0.55 with batching done in weight. The results reveal a substantial strength gain in the water cured samples to that of the air cured, having taking an average results of four cubes for each group of the samples tested for, using a Schmidt rebound hammer. The 28 day age concrete cube gave a strength difference of 5.1 N/mm2 between the water cured and air cured samples in favor of strength gain of the water cured cubes, thereby pointing to the significant of curing in terms of concrete strength development.
