Effect of Aggregate Properties on the Crushing Strength of Concrete .Apr 5, 2015 . This paper studied the effect of aggregate properties on the crushing strength of concrete. In order to achieve the study objective, three types of coarse aggregates, brick khoa, shingles stone, and black stone were used to test. And the test results show that concrete made from black stone has the highest.Study of Tensile Strength of Marble Stone (Indian White) and Black .Abstract -Rocks are weaker in tension compared to compression so tensile strength plays a very important role in rock engineering. Basically, rock structure designer avoid the tensile stresses in construction of tunnel & underground mines etc. Therefore it is very important to calculate the tensile strength of rock material.
