Effect of Deflocculants on High Alumina Low Cement
· Refractory castables are primarily a composition of refractory grains matrix components bonding agents and additives. The composition of each component is varied to get desirable properties. The commonly used hydraulic binders are Calcium Aluminate Cement but the presence of CaO results in low melting phases of Alumina refractory.

· The effects of two different 70 alumina calcium aluminate binders upon two different castable systems are examined. The behaviours of the two CACs in a conventional regular high-cement refractory castable are compared in terms of their impact upon placing properties and installed properties.
Effect of different high alumina cements on the properties
· is more than 0.25.In this project our emphasis is on self flowable castables. Self flow castables yield under their own weight and flow whereas vibratable castables will require an external load for yielding. The binding phase we use is high alumina cement(HAC).The major phases present in high alumina cement is CaO.Al2O3(CA) CaO.2Al2O3(CA2) and
Rheological Behaviors of Calcium Aluminate Cement
Calcium aluminate cement (CAC) and hydratable alumina (HA) are the most widely used binders for refractory castables. Nevertheless CAC as the binder for refractory castable generates some low melting point phases when coupled with SiO2 which deteriorate the high temperature performance of refractory castables. Although hydratable alumina (HA) bonded castables overcome the drawbacks of CAC
