Abstract: This paper presents the results of laboratory tests on the effect of lateral confinement on the behavior of a model circular footing resting on sand. The improvement of bearing capacity and settlement of footing supported by confined sand were studied. The effect of confinement dimensions such as confinement height, confinement width and confinement position on the response of footing was presented. The influence of cell, one and two sides confinement on the footing behavior was studied. One and two sides confinement were studied here to simulate the effect of permanent side support on the behavior of shallow foundations. The response of footing performance due to soil confinement compared with that observed for unconfined case was presented. The results indicate that significant increase in bearing capacity was noticed by soil confinement. The position of lateral confinement plays the important role in the improving of footing behavior. The best improvement was observed for the case o

Abstract: This paper discuss the effect of white cement on concrete properties such as fresh properties (slump), mass transport properties (Isat- sorptivity) and mechanical properties (compressive- splitting tensile). The thermal gravimetric analysis (TGA) of cement paste containing various blending of white cement with SRPC is also investigated. Concrete specimens were prepared with SRPC, water, sand and dolomite of 10 mm maximum nominal size. The blending of white cement with SRPC were 0, 10, 20,30,40,50 and 100% at w/c = 0.50. The effect of 10% SF on compressive strength of concrete made with various percentage of white cement to SRPC is also considered. The results indicated that, 30 % percentage of white cement to SRPC exhibited peak slump, the maximum compressive and splitting strength were observed at 30 % percentage of white cement to SRPC .Also, the lowest values of Isat and sorptivity were occurred at 30 % percentage of white cement to SRPC which agree with the results of compressive a
