List of Figures

• Figure 1: Measured cement particle size distributions for CCRL cements 135 (solid line) and 136 (dotted line). Curves shown are the mean values of ten separate measurements.

• Figure 2: Segmentation algorithm for separating portland cement into its components. C₃ S denotes tricalcium silicate, C ₂S denotes dicalcium silicate, C ₃A denotes tricalcium aluminate, C₄AF denotes tetracalcium aluminoferrite, and CaO corresponds to free lime.

• Figure 3: Composite RGB image of cement 135. In the composite color image, the degree of red is proportional to the Ca X-ray signal, green the Si, and blue the Al. Thus, shades of yellow would correspond to (red/green or calcium/silicon) calcium silicate phases and shades of purple would correspond to (red/blue or calcium/aluminum) calcium aluminate phases. Black is the epoxy-filled pore space. Image is 256 µm x 200 µm.

• Figure 4: Processed image of cement 135. Red is C₃S, aqua is C ₂S, green is C ₃A, yellow is C ₄AF, pale green is gypsum, white is free lime (CaO), dark blue is K₂SO ₄, and magenta is periclase. Image is 256 µm x 200 µm.

• Figure 5: Composite RGB image of cement 136. In the composite color image, the degree of red is proportional to the Ca X-ray signal, green the Si, and blue the Al. Thus, shades of yellow would correspond to (red/green or calcium/silicon) calcium silicate phases and shades of purple would correspond to (red/blue or calcium/aluminum) calcium aluminate phases. Black is the epoxy-filled pore space. Image is 256 µm x 200 µm.

• Figure 6: Processed image of cement 136. Red is C₃S, aqua is C₂S, green is C ₃A, yellow is C ₄AF, pale green is gypsum, white is free lime (CaO), dark blue is K₂SO ₄, and magenta is periclase. Image is 256 µm x 200 µm.

• Figure 7: Description of the quantitative analysis for CCRL cement 135.

• Figure 8: Description of the quantitative analysis for CCRL cement 136.

• Figure 9: Computer model (lines) and experimental results (data points) for degree of hydration of CCRL cement 135, w/c=0.40, under saturated and sealed curing conditions. Crosses indicate ± one standard deviation in experimental measurements, and generally fall within the boundaries of the data point symbol itself. Model cycle to actual hydration time conversion factor was 0.0003.

• Figure 10: Computer model (lines) and experimental results (data points) for degree of hydration of CCRL cement 136, w/c=0.40, under saturated and sealed curing conditions. Crosses indicate ± one standard deviation in experimental measurements, and generally fall within the boundaries of the data point itself. Model cycle to actual hydration time conversion factor was 0.00036.

• Figure 11: Experimentally measured (circles) and model-predicted compressive strength development for ASTM C109 mortar cubes prepared from CCRL cement 135. Solid line indicates model calibration to the 3 d measured strength while dotted line indicates calibration to the 7 d measured value. Crosses indicate ± one standard deviation from the mean, as determined in the CCRL testing program.

• Figure 12: Experimentally measured (circles) and model-predicted compressive strength development for ASTM C109 mortar cubes prepared from CCRL cement 136. Solid line indicates model calibration to the 3 d measured strength while dotted line indicates calibration to the 7 d measured value. Crosses indicate ± one standard deviation from the mean, as determined in the CCRL testing program.
