Experimental evaluation of compressive strength of steel fiber reinforced soi

Today, development of industries has caused production of different scraps. Scraps are recyclable materials left in the environment. Unlike garbage, scraps, particularly those of copper and steel, are of great financial value. The application of steel scraps mixed with soil is one of the solutions to prevent environmental risks of steel. Considering the properties of steel, its scraps made into fibers could be used to reinforce soils and improve their mechanical properties. This study scrutinizes the effects of two types of steel fibers (plain hooked-end and crimped) added to clay with different weight percentages and aspect ratios (L/D) under uniaxial compressive strength test. The results indicated that the compressive strength of steel fiber reinforced soil is to a large extent increased. However, contrary negative effects in the compressive strength are possible once the weight percentage of steel fibers in soil exceeds a certain limit.
