2/1/2006Mechanical properties such as compressive strength are necessary for the design of fusion blanket packing the small pebbles In this study collapse loads of Li 2 TiO 3 pebbles with different diameters were measured by an unconfined compression tester and contact strength of these pebbles was evaluated by Hertzian contact theory
Compressive Strength Compressive Strength is the stress in pounds per square inch (psi) that will rupture a stone sample Very rarely is the compressive strength of a stone much of a factor in stone selection A column of stone with a density of 160 lbs/cf that is 100 feet tall exerts a compressive stress of only 110 pounds per square inch
when compared to granitic crushed stone rolled pebbles are already used in the north region of Brazil being an economic alternative because they are largely found in ravines and riverbeds in the region In this way the present study compared values of splitting tensile strength of
compressive strength of cubes was considered the parameter to select the best mix proportion Cube strength of 7 days and 28 days were tested The compressive strength in wet condition was tested for two trial mix proportions to check the behaviour of the material in adverse conditions The results are presented in Table 2
strength with 29 7 N/mm 2 and 26 2 N/mm 2 respectively while the unwashed gravel with 20 mm maximum size yielded a compressive strength of 24 5 N/mm 2 at 28 days Conclusion The results prove that the size grading internal bonding and deleterious material contribute immensely to the strength of concrete made from gravel aggregate
Concrete strength values are usually specified as the lower-bound compressive strength of either a cylindrical or cubic specimen as determined by standard test procedures Different strengths of concrete are used for different purposes Very low-strength—14 MPa (2 000 psi) or less—concrete may be used when the concrete must be lightweight
