Concrete is a universal material that is used widely across the construction industry. Within a standard concrete mix, a fine aggregate and a coarse aggregate are added to the mix design to help with solidity and compressive strength in the mixture. The admixtures, additives, slump, and mix ratios will differ based on the compressive strength you're trying to attain. This paper directly reflects the results of the differences between shapes in recycled concrete used as a coarse aggregate substitute in concrete mixes. As the construction industry grows, so does outreach towards sustainability and reusing materials anywhere the industry can. Testing concrete re-batched in a new mix is sustainable but seemingly broad. The results found in this paper will shed light on the compressive strengths of re-batched concrete but centralize the focus on the differences in rounded versus jagged pieces. The research found will educate the industry on how applicable recycled jagged concrete used as coarse aggregate could be and help continue more extensive research by industry professionals to allow for potential applications in the real world.
