The terminal ballistic properties of certain concrete-polymer systems have been evaluated. Penetration and cratering measurements were made on three different types of materials 1 polymer concrete consisting of rock and sand bound by a cured polymer 2 cured portland cement concrete into which liquid monomers were injected and then cured to varying degrees of polymerization 3 latex modified concrete which differed from portland cement concrete only in the substitution of latex emulsion for portions of the mix water. Data obtained from impact of 0.30-caliber projectiles indicates that all three systems can produce structural concrete with superior terminal ballistics behavior. Penetration was reduced by up to 30 percent, and cratering by up to 100 percent, with virtual elimination of cracking in the target material.
