Drop-Weight Impact Response of Glass-Fiber Reinforced Ceramic Concrete

Tassew, S. T. / Mutsuddy, R. / Bindiganavile, V. S. / Lubell, A. S.

Abstract This paper reports on the static and impact response of a lightweight concrete fabricated using a chemically-bonded phosphate ceramic binder and expanded clay aggregates. The concrete has a density of 1700 kg/m3 and exhibits rapid strength gain. Chopped glass fibers having a length of 13 mm were included in the matrix at 0 to 2.0 % mass-fraction of the ceramic concrete. The tests were conducted on notched flexural specimens using configurations of quasi-static four-point bending and drop-weight impact three-point bending. Companion tests were performed to establish reference compressive behavior. The results show that both flexural and compressive strength increased significantly with an increase in the mass-fraction of fibers under quasi-static loading. Under impact, the flexural strength was uniformly higher compared to quasi-static loading, regardless of fiber content. However, as seen from the post-peak flexural toughness, the fiber efficiency was better under the quasi-static condition.
