The paper reports an experimental study on test specimens of Slurry Infiltrated Fibre Concrete (SIFCON) in shear and torsion. The principal variables of the test programme were (a) Aspect ratio and (b) Volume fraction of fibres. The matrix used was freeflowing cement mortar with cement-sand ratio of 1:l. A high range water reducer and set retarding synthetic superplasticiser were used to make the infiltration of mortar possible at a low water/cement ratio of 0.3. The results show an increase in ultimate torque and ultimate shear strength with an increase in fibre content and aspect ratio upto a certain limit beyond which it starts decreasing.
