Surname1 Surname: Institution: Professor: Course: Date: UNIVERSITY OF SOUTH ALABAMA September 5, 2017 Shenghua Wu, Ph.D., LEED AP Department of Civil, Coastal, and Environmental Engineering University of South Alabama Subject: CE 315 Civil Engineering Materials-Lab #1: Specific Gravity, Absorption of Coarse Aggregates, Bulk Unit Weight & Voids in Aggregates Dr. Wu, The following report includes the results of the experiment to determine the Specific Gravity, Absorption, Bulk Unit Weight & Voids in Coarse Aggregate. The experiment was conducted on August 8 th , 2017 in the civil engineering lab following the procedures outlined in the book for ASTM C127 and ASTM C29. Two experiments were carried out i.e. experiment No. 7 for determining Specific Gravity & Absorption of Coarse Aggregates and experiment No. 9 for determining the Bulk Unit Weight & Voids in Aggregates. The research team included Ali Alshehri and other three members.

Surname2 The results of the experiment were computed as follows. For Experiment No. 7: Bulk Specific Gravity = A/ (B - C) = 7.12/ (7.98 – 4.1760) = 1.87 Bulk Specific Gravity (SSD) = B/ (B – C) = 7.98/ (7.98 - 4.1760) = 2.10 Apparent Specific Gravity = A/ (A - C) = 7.12/ (7.12 – 4.1760) = 2.42

What students are saying

• 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.
