Keywords : CPA – Coconut pith ash Abstract :
Sustainable development is the need of the hour, we have to take lead in initiating activities that would minimize the exploitation of our natural resources resulting in their effective utilization. With the increase in demands and need for infrastructural development, there is an urgent need to focus attention on low-cost alternative construction materials.This work presents the results of laboratory tests carried out using Coconut Pith Ash (CPA) as a partial re-placement for cement in concrete. Concrete cubes, cylinders & beams were casted and tested at curing ages of 7, 14 and 28 days using 5,10,15 and 20 as partial percent replacement levels. The slump test result shows that the workability of the concrete decreased as the CPA content increased. Results Showed that the Compressive, Split tensile and Flexural Strength of the CPA. Concrete attains its strength with curing age but the strength decreases with increasing percentage of coconut pith ash. The strength gained at 28 days for 5%, 10%, 15% and 20% are compared. The results reveal that we can replace the coconut pith ash by 10% to obtain the desired strength of M20 concrete
