INVESTIGATION OF CONCRETE CONTAINING CONDENSED SILICA FUME. FINAL REPORT

The properties of hydraulic cement concretes containing silica fume were investigated to assess their suitability for use in overlays with a minimum thickness of 1 1/4 in. The properties studied were compressive and flexural strengths, bond strength, modulus of elasticity, permeability, freeze-thaw resistance, thermal expansion, and drying shrinkage. The characteristics of air voids in the hardened concrete were determined by petrographic examination. The study was conducted in two stages: the first to determine mixture proportions that would yield satisfactorily high strengths and low permeabilities, and the second to conduct the man testing program. Silica fume from two sources was used. Concretes made with silica fume from either source at a water-cement ratio of 0.40 or lower and a replacement rate of 5% yielded the desirable properties. It is expected that concretes made with silica fume can provide a cost-effective protective system for bridge decks when placed in overlays with a minimum thickness of 1 1/4 in.
