Foam concrete with pulverized cow bone as partial replacement of cement utilizing demolished concrete as aggregate

Abstract

This research discusses the use of cow bone powder as a partial replacement for cement in manufacturing foamed concrete. Cow bone powder is a waste product with a high calcium content that may be used as a partial substitute for cement. Cow Bone powder is replaced in cement at 18%, 20%, and 25%. The study aims to test the physical and mechanical properties of the cow bone powder and demolished concrete mixture compared to conventional foam concrete in terms of compressive strength, air voids, and fire resistance test. Comparing foam concrete with cow bone to ordinary foam concrete, the compressive strength of the foam rose by 18% and 20%. However, foam concrete’s compressive strength dropped to 25% cow bone. The results show that cow bone powder significantly affects the foam concrete’s compressive strength. The study is limited to concrete walls, but it can serve as a reference for future researchers interested in developing durable concrete materials.
