EFFECT OF CURING METHODS ON THE CHARACTERISTIC STRENGTH OF CONCRETE WITH LATERITIC SAND AND PERIWINKLE SHELL


ABSTRACT


This study investigates the effect of curing methods on the compressive strength of concrete with fine and coarse aggregates components fully and partly replaced with lateritic sand and periwinkle shell respectively. A total of 90 cube specimens of 100 x 100 mm dimensions for each percentage replacements ranging from 10 to 40% percentage replacement of fine aggregate with lateritic sand and coarse aggregate with periwinkle shell and 100% percentage replacement of fine aggregate with lateritic sand and coarse aggregate with periwinkle shell respectively were cast and cured in water and open air for 7, 14 and 28 days. The water cement ratio used is 0.65. 1:2:4 and 1:3:7 mixing ratios were adopted. The results show that compressive strength of concrete generally increases irrespective of the percentage replacement and curing methods as the curing age increases. Compressive strength of concrete with lateritic sand and periwinkle shell as partial replacement up to 20% is the highest compared to other percentage replacements irrespective of the curing ages and curing methods.


Key words: Concrete, lateritic, sand, strength, periwinkle shell.
