                                     The addition of supplementary materials such as fly ash and silica
                              fume affects the induction period in cement hydration. The relative effects
                              have been illustrated by conduction calorimetric curves. [80]
                                     The relative effects of 10% of fly ash, limestone, or sludge on the
                              hydration of portland cement have been investigated by DTA/DTG/TG and
                              XRD. Based on Ca(OH)  estimation, it has been concluded that lime sludge
                                                   2
                              and limestone enhance hydration of cement compared to that by slag or fly
                              ash. [81]
