Effect of Curing Time on the Properties of CAC Bonded Refractory ...
Webstudied the drying of two refractory concrete 3types with 8 mass-% and 3,5 mass-% CA cement. The compressive strength of one castable was 51,7 MPa (25 °C) and the other castable was 12,4 MPa (25 °C); one normal strength concrete and one low strength concrete. The diametral tensile strength was 8,27 and 0,09 MPa, respectively. WebThe total drying time is then: t = (1 / 0.113) [(0.25-0.10) / 0.10 + In (0.10 / 0.03)] = 8.856 (1.5 + 1.204) = 23.9 ks (6.65 h) _ _ ...
