Mechanical Characteristics of Pavers with Iron Ore Tailings

Abstract:

The objective of this study is to evaluate experimentally the mechanical compressive strength and static modulus of elasticity of concrete pavers for floors made with iron ore tailings as aggregate concrete. Pavers were manufactured with four different concrete mixtures (cement, natural sand, industrial sand, iron ore tailings, crushed stone), and performed simple compression tests to determine the compressive strength and modulus of elasticity. The pavers manufactured with those concrete mixtures showed greater strength specified by the Brazilian standard. It was possible to find a correlation between modulus of elasticity and compressive strength.
