Comparative Study Of Compressive Strengths Of Palm Kernel Shell Concrete Using Different Curing Methods
This study considered comparative study of different methods of curing on
compressive strength of concrete using palm kenel shell. Concrete cube specimens of mix
1:1:2 were prepared with water-cement ratio of 0.55. The cubes were cured using four
methods (Ponding curing, Sprinkling curing, Wet-curing (Saw dust) and Open-Air curing)
for testing ages of 7, 14, 21 and 28 days when their compressive strengths were
determined. The results showed that Ponding curing method has the highest compressive
strength at 28days curing of 17.07N/mm2, followed by Sprinkling curing of 15.78N/mm2.
Wet-curing method has compressive strength of 14.48N/mm2 and Open-air curing has
compressive strength of 13.11N/mm2. This shows that there is significant difference in the
curing methods.
