ABRASION RESISTANCE OF FIBRE REINFORCED CONCRETE

This paper discusses laboratory tests of fibre-reinforced concrete conducted at the Central Road Research Institute (CRRI) in India. It first lists 13 advantages and two disadvantages of fibre-reinforced concrete, and five existing methods for the abrasion testing of cement concrete which have several disadvantages. The CRRI investigations studied the compression, flexure, flexural fatigue, shear, shrinkage, and abrasion of fibre-reinforced concrete. Details are given of the apparatus and procedure of the pneumatic test, developed at CRRI to study abrasion. Impact of the abrasion medium at an angle of 90 degrees simulates the cutting action of a bullock cart. Inclination of the abrasion jet at 10 degrees to the vertical gives a shearing force like wheel drag dislodging particles. High particle velocity simulates degree of impact. Specimens with various proportions of steel fibre were tested. Increase in the proportion of steel reduces abrasion loss and increases abrasion resistance.
