      Fused Calcium Aluminate Cement
      Addtime:2011/10/19 14:48:11   Hit:0   Add to Favorites

            Fused Calcium Aluminate Cement is melted in electric arc furnaces by adopting the excellent alumina and limestone as its raw materials. Its characteristics are stable quality, small water demand, fast and adequate hydration, early high strength, etc. It is the bonding agent for producing all kinds of high performance monolithic refractories.     Type:AL-70, AL-80, AL-90
