Abstract

Objectives: To determine the compressive strength of concrete with e-wastes as additives after a curing period of 28 days. Methods/Analysis: Concrete was produced with 1%, 2% and 3% e-wastes utilizing the Printed Circuit Boards (PCB) made as chips using the Class A mixture with the control. The compressive strength was determined. Findings: Concrete passed the allowable compressive strength with the control sample, 1%, 2% and 3% e-wastes which yielded to an average value of 20.85 MPa, 21.75 Mpa, 24.75 MPa, and 23.18 MPa respectively. Improvement: Addition of electronic wastes improved the strength of concrete.
