    Strength is an important property to be looked into before selecting stone as a building block. Indian standard code recommends, a minimum crushing strength of 3.5 N/mm 2 for any building block. Table 1 shows the crushing strength of various stones. Due to the non-uniformity of the material, usually, a factor of safety of 10 is used to find the

Rubber ash and rubber fibers were used to develop two series of rubber ash concrete (series I) and hybrid concrete (series II) mixes. The natural fine aggregate was replaced by rubber ash (by volume of 5%, 10%, 15% and 20%) in series I; whereas in series II, the amount of
