Abstract
A new castable steel fiber reinforced concrete composition is described composed of Portland Cement, fly ash, fine aggregate, gravel or crushed stone, water, high range superplasticizing water-reducing admixture, and steel fibers. The concrete may be mixed in conventional mixers and cast in open top molds to form modular panels for use in the construction of security vaults. The cast panels have outstanding engineering properties resistant to burglarious attack measures such that multi-paneled vault walls resist burglarious attack as outlined in Underwriters Laboratories Standard No. 608 in thicknesses of 8 inches for 1 hour and 11 inches for 2 hours. New casting procedures for the concrete and new vault construction procedures using modular panels cast from the concrete also are described.
