Figure 1: Two-dimensional processed scanning electron microscopy (SEM)/X-ray image for cement 152 issued by the CCRL in January 2004. Color assignments are: brown- C3S, blue- C2S, grey- C3A, white- C4AF, yellow- gypsum, red- K2SO4, green- free lime, aqua- free silica, and pink- periclase (magnesium containing phase). Image is 256 μm x 200 μm.

Figure 3: Comparison of CEMHYD3D model and experimental data of Gutteridge and Dalziel [4] for the influence of fine (rutile- TiO2) filler on cement hydration.
Figure 4: Experimental and CEMHYD3D v3.0 model estimated degrees of hydration for CCRL cement 152 with and without 20 % by mass fraction limestone substitution for w/s=0.435, cured under saturated conditions at 20 ºC [40].
Figure 5: Experimental and CEMHYD3D v3.0 model estimated degrees of hydration for CCRL cement 152 with and without 20 % by mass fraction limestone substitution for w/s=0.35, cured under saturated conditions at 20 ºC [40].
Figure 6: Influence of additional alkalis (potassium and sodium, either sulfates or hydroxides) on degree of hydration for experimental mixtures and simulations using CEMHYD3D v3.0.
