**3.3 Density**

The measured density for the mixes G10A, G20A, G30A, G40A, G50A and G0A are respectively 2267, 2306, 2378, 2392, 2384 and 2240 kg/m3 as shown in **Figure 10**.

and the density values for mixes G10A', G20A', G30A', G40A', G50A' and G0A are 2254, 2258, 2327, 2385, 2346 and 2217 kg/m3 as shown in **Figure 11**. Here again, upto 40% replacement, increase in density could be noticed.
