Figure 12
The illustration displays two cumulative bar charts, labeled “a” on the left and “b” on the right, both illustrating “Compression Strength (Megapascals)” on their vertical axes, ranging from 0 to 30 in increments of 5. The horizontal axis of both charts represents different concrete mix compositions. A common legend at the top of the image indicates that the bar colors correspond to different exposure temperatures: white for “Ambient,” red for “200 degrees Celsius,” orange for “400 degrees Celsius,” and blue for “600 degrees Celsius.” Each bar also features error bars at its top, indicating variability. Chart “a” presents data for “Control” mix and mixes with varying percentages of crumb rubber (C R): “C R-05,” “C R-10,” “C R-20,” “C R-30,” “C R-40,” and “C R-50.” For each mix, there are four vertical bars corresponding to the four temperature conditions. The general trend shows that as the percentage of crumb rubber increases, the compression strength tends to decrease across all temperature conditions. Also, for a given mix, the compression strength generally decreases as the exposure temperature increases. Chart “b” mirrors the structure of chart “a,” but presents data for mixes with varying percentages of RESIN 8 (R 8): “Control,” “R 8-05,” “R 8-10,” “R 8-20,” “R 8-30,” “R 8-40,” and “R 8-50.” Similar to chart “a,” this chart also shows a general trend of decreasing compression strength with increasing RESIN 8 content and with increasing exposure temperature.Pre-and post-heating load capacity of SCB incorporating (a) CR and (b) R8.
