Flexural Strength of Ferrocement Slab Made of Slag Sand Partially Replaced With Iron Ore Tailings: An Experimental Investigation

Abstract

This chapter investigated about Flexural Strength of a Ferrocement Slab Made of Slag Sand Partially Replaced With Iron Ore Tailings. Iron ore tailings (IOT) are waste material obtained from the process of smelting iron. The rapid growth in the surface mines led to the production of Iron Ore tailings which remains as overburden. The materials used in the present investigation were carefully selected and tested in the laboratory to assess the quality and suitability of making the specimen in the right way. Investigation of 48 slab panels of 700mm x 300 mm size with thicknesses 25 mm and 30 mm was conducted using 1 and 2 layers of weld mesh reinforcement cast with different percentages of iron ore tailings. Slabs were tested in a Universal Testing Machine, which showed good results with improved flexural strength when 15% of iron ore tailings were used. Increasing the thickness of the slab made of 10% IOT added to the mix, increases the load-carrying capacity by 24% more than the 0% IOT mix. Increasing the number of layers of mesh increases the yield load by 36% more than the single-layered slab and reduces the sudden appearance of cracks.
