- Abstract
- Mature tricalcium silicate and portland cement pastes were studied by scanning electron microscopy with backscattered electron and x-ray imaging. Distinct differences in paste microstructure were observed in both tricalcium silicate and portland cement pastes with different water-solid ratios and hydration temperatures. In contrast, few differences were observed in microstructures of C₃S and portland cement pastes at equal water-solids ratios. X-ray imaging showed the individual elements within the paste to be unevenly distributed.
