Preliminary Sound-Abatement Tests Using Shock-Attenuating Concrete (SACON) and Other Materials, Big Black Test Facility
Abstract
Two structural concepts, a tunnel and an igloo, were constructed at the US Army Engineer Waterways Experiment Station using a shock-attenuating concrete (SACON) to determine the possible sound-abatement properties. Both structures and the SACON displayed sound abatement properties, as registered on hand-held sound level meters, when an M-16-Al rifle was fired in certain positions in and near the two structures. A noticeable reduction in sound was obtained by the use of the material and configurations of the two structures. The project mixtures were composed of two categories of Portland Cement Concrete: (performed foam and expanded polystyrene beads (EPSB)), each with steel fibers, polypropylene fibers, or alkaline-resistant glass fibers for reinforcement. Firing tests indicated that the six mixtures performed successfully, with the steel fiber-foamed concrete (designated WES 6) being the best performer.
