Compressive Strength Improvement of Lightweight Concrete by Incorporation Waste Materials: An Experimental Investigation

In the world of depletion of resources, using recycled materials is getting more and more interesting, since recycling generally reduces the need for extracting, refining, and processing raw materials. In this study, attempts to investigate the effect of two types of steel fibers (staples) on concrete compressive strength have been experimentally accomplished. The different fibers at constant fractions of 0.5%, 1%, 1.5%, and 2 % by the weight of cement are used as reinforced agents with different curing duration times of steel fibers-normal concrete samples. The results obtained by the compressive strength test showed a significant improvement in the concrete compressive strength up to 47.8 MPa could be on hand with such simple reinforcement.
