Abstract
This this paper, the influence of six curing methods (water, air, moist soil, jute bag, air/water and water/air) on the compressive strength of concrete cube specimens that contain laterite fine aggregate is investigated. Three different mixes of cement, laterite and gravel were used: I : 11: 3 ;I: 2: 4 and I : 3: 6 with water/cement ratios of 0.62, 0.75 and 1.02 by weight respectively. Four curing ages of 7, 14,21 and 28 days were adopted. The results showed that the strength that a particular mix can attain is affected by the curing method used. The water/air curing technique gave the highest strength values of28.2 Nmm: +for 1 : 11: 3; 23.9 Nmm: 2 and 17.4 Nmrn: 2 for
I : 2: 4 and I : 3 : 6 mixes respectively, while the air-cured specimens gave the lowest strength values of 17.2 Nmm=i for I: 1~:3, 16.8 Nmmr ? and 8.0 Nmmr= for 1 :2:4 and I :3:6 mixes. The higher the cement/aggregate ratio the higher the strength. Generally, there was increase in strength with age irrespective of the mix and the curing technique.
