shown in table 1 as oxides sample compositions were prepared by combining portland class h cement with freshwater in an amount of 4 3 gallons per 94 pound sack of cement the density of the resulting slurries was 16 4 pounds per gallon in sample composition nos 2 u2013 7 9 and 10 fibers were also included wherein the amount and type of fiber included in each sample was varied further sample composition nos 8 u2013 10 were foamed to these samples zoneseal u2122 2000 foaming agent was added in an amount of 2 by volume of the freshwater and the samples were then foamed with air to a density of 12 5 pounds per gallon after preparation the sample compositions were cured at 140 u00b0 f for 72 hours thereafter standard mechanical tests were performed on the set sample compositions in accordance with api recommended practices 10b twenty second edition december 1997 to determine the compressive strength and the tensile strength the young 39 s modulus of elasticity and the poisson 39 s ratio were determined in accordance with as u2122 d3148 02 the results of these tests are shown in table 3 therefore example 2 indicates among other.
