This paper presents the results of an experimental investigation of the properties of superplasticized fiber reinforced concrete. Essentially, two groups of specimens were tested; the first to study the relationship between compressivie strength and modulus of rupture and the second to study time dependent behavior. Altogether, more than 70 mixture proportions were investigated. The first group of specimens was tested to obtain 28 day compressive strength and 28 day modulus of rupture. The second group of specimens was tested in compression, flexure and for impact resistance at 1, 3, 7, 28 and 90 days. Based on the experimental results, an empirical equation (similar to the one specified in the American Concrete Institute Code 318-83) is proposed, that relates 28 day compressive strength to the 28 day modulus of rupture.
