For specimens' humidity, a 20% final mass was ensured. They were casted and dried at room temperature during 6 days. Afterwards they were dried by a muffle furnace thus increasing temperature at IOOC per hour, until achieving 700C and, then directly rising up to 900C during 6 hours.
En las probetas se garantizó una humedad del 20% de la masa final y fueron moldeadas y secadas a temperatura ambiente durante 6 días; posteriormente se sometieron a quemado en una mufla, con incremento de temperatura de 100°C por hora hasta alcanzar 700°C y ascender directamente a 900°C durante 6 horas.
