**3.4 Flexural strength**

The flexural strength values of mixes G10A, G20A, G30A, G40A, G50A and G0A are 2.35, 3.59, 4.39, 6.5, 5.84 and 5.35 MPa respectively as shown in **Figure 12**. Flexural strength test also yields the same inference that increase in strength upto 40% replacement of flyash by GGBS and getting decreased after that.
