The Inter-University Symposium on Asian Megacities, Suwon, South Korea, July 11–13, 2024 INVESTIGATION OF THE COMPRESSIVE STRENGTHS OF COCONUT SHELL AS PARTIAL ALTERNATIVE OF COARSE AGGREGATES IN CONCRETE MIX John Arvin R. Manaloto1 1 University of the Philippines, Diliman, Quezon City, Philippines, jrmanaloto@up.edu.ph, ABSTRACT As the infrastructure development continues to thrive in the Philippines, the demand for concrete in the construction industry also grows.
