TECHNOLOGICAL UNIVERSITY OF THE PHILIPPINES MANILA COLLEGE OF ENGINEERING CIVIL ENGINEERING DEPARTMENT CONSTRUCTION MATERIALS AND TESTING LABORATORY NAME: CASIA, MA. CRISTINA B. DATE: JULY 23, 2018 CRS.YR.SEC: BSCE-4E ENGR. MARJUN B. MACASILHIG EXPERIMENT NO. 3 “SPECIFIC GRAVITY OF COARSE AGGREGATES” I. SIGNIFICANCE OF THE TEST: Specific gravity is the ratio of the mass (or weight in air) of a unit volume material to the mass of the same volume of water. In this test the specific gravity of coarse aggregate is evaluated using the principle of buoyancy. Specific gravity is a quick indicator of the suitability of an aggregate. Low specific gravity frequently indicates porous, weak and absorptive materials, while high specific gravity often indicates high quality. The data obtained from this test can be used in designing and controlling the weight of concrete. At the end of the test, the percentage of water absorption of the coarse aggregates will also be evaluated. The term absorption is defined as the capacity of the coarse aggregate to

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
