Shock-absorbing concrete, cellular concrete, was developed and used in several experiments at the Nevada Test Site to reduce or attenuate ground shock produced from blast loadings. In conjunction with the field experiments, an analytical investigation involving the use of computer calculations to predict the shock propagation through the concrete was also initiated. One of the requirements of this effort involving computer codes was the development of constitutive relations of the concrete. The report documents the results of laboratory tests conducted on a 62-pcf-density cellular concrete to determine the static response of the concrete. An effort was made to test the mix in several states of stress, including uniaxial strain, hydrostatic compression, and triaxial shear, to determine the response aspects considered most important in the development of its constitutive properties.
