A secondary containment structure formed of a slurry infiltrated fiber concrete composite is used above ground or underground to enclose material storage containers and to safely contain any materials leaked from the container. The structure is a hollow configuration having a bottom wall, at least one side wall, and a removable top wall. The interior volume of the structure exceeds the volume capacity of the container which is enclosed therein. The bottom wall is sloped to facilitate drainage of any liquid leaked from the container and the top wall may have covered apertures to allow access to the container. The structure is formed of a slurry infiltrated fiber concrete composite which is produced by first placing a plurality of individual short fibers or fiber mats of organic or inorganic materials into a form to create a bed of fibers substantially filling the form and having a predetermined fiber volume density and then adding the slurry mixture into the form to completely infiltrate the spaces between the fibers. The slurry mixture includes a composition of Portland cement, fly ash, water, a high range water reducer (superplasticizer), and may also include fine grain sand, chemical admixtures, and other additives. Due to its fiber volume density and method of manufacture, the resulting secondary containment structure has thinner walls, greater strength, and a gross weight significantly less than conventional reinforced and pre-stressed concrete structures of the same size.
