The foamed test samples were allowed to set for 1 week at 140� F. and atmospheric pressure after which portions of the test samples were subjected to various tests to determine their properties. More specifically, shear and hydraulic bond strength tests were conducted in accordance with the procedures of Example 1, and unconfined uniaxial and confined triaxial strength tests were conducted and Young's Moduli (also known as moduli of elasticity) and Poisson's as determined as well as bulk compressibilities, shear moduli and tensile strengths, all in accordance with the standardized tests and procedures of the American Society for Testing and Materials (ASTM) set forth, for example, in ASTM Section D 1456. The results of the tests and determinations are set forth in Table IIB below.

The various test samples were allowed to set for 6 days at 140� F. and atmospheric pressure after which portions of the test samples were subjected to a number of the tests and determinations described in Example 2 above to determine their properties, i.e., unconfined compressive strength tests, tensile strength tests and yield strength tests at 1,000 psi confining pressure were conducted and Young's Moduli and Poisson's ratios were determined. The results of the tests and determinations are set forth in Table IVB below.
