Figure 2.
The image features two microscopic images of mineral structures. The upper section presents a grey-scale electron microscope image displaying various mineral textures and patterns, including cracks and irregular shapes. A scale bar indicates a measurement of one hundred micrometres. The lower section shows a colour-coded image indicating the calcium/silicon atomic ratio, with blue, green, red, and orange regions representing varying ratios. A legend on the right provides specific atomic ratio values ranging from zero point ten to four, with a corresponding colour gradient. A scale bar in this section also measures one hundred micrometres. The images are arranged with the grey-scale image above and the colour-coded image below, both having the same magnification and scale.C-S-H transformed from ASG within a crack (adapted from Yamada et al. (2013)). The upper image is a backscattered electron micrograph, while the lower image shows calcium/silicon atomic ratio mapping obtained through electron microprobe analysis. The black part in the most upper position of the crack is a void. A full-colour version of this figure can be found on the ICE Virtual Library (Link to Emerald InsightLink to the website of emerald.)
