4-33. Following are results of gradation tests on three aggregates: Aggregate A 100% 92% 41% 19% 7% 4% 2% 1% Passing 25 mm (1 in.) 19 mm (3/4 in.) 9.5 mm (3/8 in.) 4.75 mm (No. 4) 2.36 mm (No. 8) 600 μm (No. 30) 300 μm (No. 50) 75 μm (No. 200) Aggregate B 100% 77% 60% 42% 36% 28% Aggregate C 100% 96% 79% 40% 16% 3% Combine these to give a gradation falling approximately in the center of the specification given in Section 4-5.1.
You are given a result of the gradation test of aggregate, calculate and plot the gradation curve on the given semilog graph shee
please quickly thanks !
