Figure 13.
The image contains two line graphs labeled (a) and (b), each depicting the expansion percentage of materials as a function of the proportion of highly reactive andesite, ranging from zero to one hundred percent on the horizontal axis. The vertical axis represents expansion percentage, ranging from zero to twenty-five percent for graph (a) and zero to eighteen percent for graph (b). Each line in the graphs is color-coded to represent the age at evaluation in days, with a legend indicating the corresponding colors for specific ages, such as three hundred, two hundred and seventy-three, and so on, down to nine days. Both graphs feature multiple data points connected by lines, with graph (a) showing a more gradual increase and decrease in expansion compared to graph (b), which appears to have a more abrupt change in response to the andesite proportion.Expansion behaviour of concretes with different ratios of highly reactive andesite and two different alkali contents: (a) 3.0 kg/m3 alkali; (b) 4.0 kg/m3 alkali.
