Figure 6.
The graph illustrates the relationship between manganese oxide nanofiber percentage, presented on the horizontal axis, and two metrics: bulk density and apparent porosity on the vertical axes. The left vertical axis indicates bulk density, measured in grams per cubic centimetre, while the right vertical axis depicts apparent porosity as a percentage. The graph features a blue square symbol representing apparent porosity and a magenta triangle for bulk density, with both variables marked clearly. The data points for bulk density show an increasing trend with higher percentages of manganese oxide nanofiber, contrasting with a decreasing trend for apparent porosity. Each line connects the data points, allowing for visual interpretation of the relationship between the two properties concerning the changing percentages of manganese oxide nanofiber.Bulk density and apparent porosity of geopolymers containing various ratios of MnO2 nanofibres
