8.7 A ceramic with Ke = 4 MPa m2 contains pores with radius a = 5 um due to incomplete sintering. These pores lead to a decrease in the failure stress of the material in both tension and compression. One in every ten grain- boundary junctions contains a void; the grain size of the ceramic is 50 µm. The ceramic fails in compression when the length é of each crack generated at the voids equals one-half of the spacing between the voids. (a) Determine the compression strength of the ceramic, using the equation from Sammis and Ashby. (b) Determine the tensile strength of the ceramic, assuming flaws with size a.

Asphalt Binders and Mixtures

Asphalt binders are subsidiary products procured during the refining process of petroleum while manufacturing gasoline, diesel, and similar petroleum products. Asphalt binders are obtained from the residue that remains after the distillation of petroleum, this residue is further subjected to steam distillation and oxidation to remove the traces of gas oil present in the residue. Certain additives or modifiers are also added to asphalt binders to alter them to suit different applications.
