The MAC CRETE range of conventional castables is suitable for moderate and high heat duty applications. These are calcium aluminate bonded refractory concrete for application in temperatures upto 1400° c. These can be either vibration cast or poured. The grading of these products is formulated such that they can be gunned if required. High alumina High purity Conventional Castables, The MACHEAT range of high alumina conventional castables is made with aluminus aggregate and high purity high alumina refractory cement. These are suitable for use in critical applications upto 1800° c. They exhibit high volume stability, good thermal shock resistance and excellent hot strength. These castables are installed by both vibration and hand placement. Low Cement Castables The MACVIB range of low cement castables are available in 45% to 90% Al2O3 content. They are made with aluminus and mullite aggregates and high purity high alumina cement. These are suitable for extreme service conditions and have application temperatures upto 1800° c. These products are distinguished by their high volume stability, low porosity, better corrosion and erosion resistance, good thermal shock resistance and excellent hot strength. Installation of these castables is by vibration only.
