Table 2. Physical properties of coarse aggregate samples 4.2 Petrographic examination of coarse aggregates


All six coarse aggregate samples were subjected to petrographic examination as per IS: 2386 Part VIII, and their results are as follows: 4.2.1 Coarse Aggregate, CA-1


Petrographic studies conducted on coarse aggregate CA-1 (Figures 1a and 1b) indicated that the sample was fine to medium grained. The modal composition is given in Table 3.
