Figure 8.
The bar graph displays compressive strength in megapascals on the vertical axis ranging from zero to thirty-five, with labels for specific values. The horizontal axis indicates the percentage of manganese oxide nanofiber, showing three categories: zero point one, zero point three, and zero point five. Each bar is filled in a solid colour and includes numerical values at the center, representing the compressive strength for each percentage: twenty-three point four three for zero point one, twenty-seven point nine six nine for zero point three, and twenty-three point nine three eight for zero point five. The graph includes error bars indicating variability in the data.Compressive strength of geopolymers containing various ratios of MnO2 nanofibres
