As shown in Figure 8 , with the heating rate increasing from 0 to 20 °C/min, the apparent porosity possesses an increasing trend; however, when the heating rate further increases to 30 °C/min, it decreases slightly because of the pores’ shrinkage caused by the hydration of the matrix surrounding the pores [ 35 , 40 ].
