The scope of this thesis encompasses the investigation of the feasibilities of using a locally and/or readily available heavy aggregate for high density concrete. Such an aggregate was found to be available in Socorro, New Mexico. The Socorro Manganese Corporation has a stockpile of over 7,000 tons of high-grade manganese ore (specific gravity = 4.5) potentially suitable as a heavy aggregate, and some of which was used for this research. Along with the manganese ore was used ferrophosphorous, a very heavy aggregate manufacture by the Victor Chemical Works (specific gravity = 6.5), to obtain a range of densities that would cover the minimum to the maximum required in biological shielding.
