Abstract This study aims to enhance both the material properties and geometric design of cement roof tiles. While Korean traditional roof tiles have a long history, they've often lacked academic input for material enhancement and geometric refinement. This research unfolds in two parts: an experimental phase focusing on boosting the strength and strain capacity of high-performance lightweight concrete (HPLWC) tiles using industrial byproducts like silica fume and recycled powder, and a finite element phase dedicated to optimizing tile geometry for improved resistance against external loads. The experimental phase involved density tests to optimize material packing and the use of air-entraining admixture to reduce self-weight. Results from the experimental phase yielded high-strength concrete (HSC) with recycled powder and high-performance lightweight concrete (MPEWC) using substantial air-entraining admixture and recycled powder. The analytical phase concentrated on reducing overall thickness and optimizing cross-sectional shape with green HPLWC.
