Abstract: DESTACAMENTO, REY G. and MANALO, IVY L. Coconut Shell Ash as Supplementary Cementitious Material for Concrete. Undergraduate Thesis. Bachelor of Science in Civil Engineering. Cavite State University Indang, Cavite. April 2016. Adviser: Engr. Renato B. Cubilla. The demand to find alternative materials to existing typical ones has exerted researchers to work and investigate on the possible materials substitute to cement. The study aimed to determine if the concrete mix with partial component of coconut shell ash can be used as replacement for cement. The concrete mixtures have been mixed with 5 percent, 10 percent, and 15 percent of coconut shell ash as partial replacement for cement and another mixture for control. Thirty-six numbers of 6 inches in diameter by 12 inches in height cylinders were cast, cured and went through compressive strength test. The maximum compressive strength of 12.41 MPa (1800 psi) was recorded at control mixture at 14th day. Experimental results have indicated that the more coconut shell ash being added, the compressive strength of the mixture decreases. None of the specimen met the minimum standard for class A concrete mixture. From the results obtained, it can be concluded that coconut shell ash can be used as supplementary cementitious material but does not improve the strength of the concrete. Mixture A, B, C and D which has compressive strengths of 12.41 MPa (1800 psi), 10.79 MPa (1566.67 psi), 9.84 MPa (1426.67 psi) and 8.19 MPa (1186.67 psi) respectively can be recommended for road curves, pathways, gutters, binder riprapping, ruble masonry, residential slab, and concrete walls.
