*Thermoactivation procedure of RC according to various authors.*

mortar was analyzed by Kalinowska-Wichrowska et al. [63]. The maximum compressive strength was attained for RC treated at 650°C for 80 minutes.

The cooling procedure may occur inside the kiln at low cooling rates or may be accelerated by means of cooling devices, following the same philosophy adopted in OPC production [45, 48, 54, 61]. Serpell and Zunino [56] did not find significant changes when the cooling rate was accelerated.
