Abstract:

Small-scale cratering experiments are being conducted by the Civil Engineering Research Facility with systematic variation in the parameters of the experiments, especially in the charge configurations and media employed in the test beds. Before cellular foam concrete could be used in the small-scale cratering studies, it was necessary to understand its behavior in specific cratering environments and to determine the reproducibility of the results. Therefore, to acquire this information, eight preliminary high-explosive shots were fired on foam concrete pads. These shots demonstrated that crater shapes and sizes, type and quantity of ejecta, and fracture patterns are reproducible, and that foam concrete is a suitable material for simulating weak, porous rock.
