The tests on concrete cylinders fabricated from materials used in construction of Port Allen Lock indicated an average compressive strength and modulus of elasticity which are in reasonably close agreement with values obtained in an extensive laboratory investigation conducted prior to construction to determine the thermal, elastic, and other properties of the Port Allen Lock concrete. Therefore, the properties of the concrete as determined in the laboratory can be applied with assurance to the concrete placed in the structure. Despite considerable deviations, the average density of the sand backfill, as placed, was equivalent to standard Proctor maximum density. The average density corresponded to a relative density of 74. The average angle of internal friction of the backfill was estimated.
