Concentration Effect of Sodium Carbonate and Sodium Aluminate as Accelerator and H_2O Mixing against Physical Properties: Flow ability, Setting Time, and Strength in Low Cement Castable Refractory Product (Case Study: PT.Indoporlen)

摘要

The research was intended to analyze effect of comparison concentration between accelerator and H_2O mixing against characterization of flow ability, setting time and strength at low cement castable refractory product (case study at PT. Indoporlen Refractory), Shown the kinds of accelerator sodium aluminate and sodium carbonate have good characterization result against flow ability and setting time while additional H_2O mixing conclude to good strength with different kinds of temperature at 110 °C, 900 °C and 1450 °C which revealed the measurement are above to allowed specification and as well the strength test coming from accelerator of sodium aluminate and sodium carbonate in various concentration 0.01% until 0.04% and with various of H_2O mixing 5.0 until 6.5% achieves the strength above in allowed specification of PT.Indoporlen.
