Concrete is the basic engineering material used in most of the civil engineering projects. It is extremely used because of the ability in possessing high compressive strength and can be moulded into any desired shape. In order to overcome the poor tensile strength of concrete, fibers are introduced in the matrix. In this research work, burr wastes obtained from CNC turning process in lathe industry were disposed as wastes in open lands in the proximity of the industries causing an hazard to the environment. Hence, these wastes were tested as fiber material in the form of micro-reinforcements in the concrete. Burr wastes were added to the concrete in volume fractions Vf = 0% to 2.0% and tested for its split tensile strength, compressive strength and flexural strength. The results of the experimental tests revealed that the compressive strength and flexural strength of burr waste concrete increased from 16.16% to 23.36%and 117% to 124% respectively for Vf = 0.5% to 2.0% at 28 days strength in comparison with concrete made without burr waste. The tensile strength of burr waste concrete increased upto 6.06% for Vf = 0.5% at 28 days strength when compared to conventional concrete. From the experimental investigation, it was observed that the addition of burr wastes as micro reinforcements in the concrete had significant improvement in terms of concrete strength. © 2020 Elsevier B.V., All rights reserved.
