In this paper, Mortar was prepared from medium alumina refractory, bricks crashed as a mean material and (kaolin, bentonite) as biendering materials. Refractory bricks was crushed, grinding, milling then sieving to three particle size fine (1.18>fine >0mm) medium (2.36>medium>1.18mm) crush (400cm>coarse >2.36mm) mixed with kaolin or bentonite with ratios (10,15,20,30,40) wt.% specimen was forming by wetting method, then drying at laboratory temperature for (24 hrs.) at last firing at (1200)°C Linear Shrinkage, Apparent porosity, apparent density, Water absorption was measured: the result showed that the linear shrinkage (L.Sh) increases with the increasing of (adding kaolin ratio) from (5% at kaolin to 30% to kaolin ratio 40%) and for bentonite. A longitudinal contraction visit versus a decrease in the apparent porosity, an increase in the apparent density, and a visit to the thermal conductivity, corresponding to a decrease in the specific heat capacity.
