Taguchi Experimental Approach to Laboratory Evaluation of Static Modulus of Elasticity of Recycled Aggregate Concrete

Akinkurolere Olufunke Olanike

This paper looks into the static modulus of elasticity of recycled aggregate concrete using experimental method. Modulus of elasticity plays an important role in the life of concrete structure because it affects the serviceability and structural performance of concrete structure. Taguchi approach was used to prepare the materials and reduce the number of experiments required. Orthogonal array L16 (45 Series) which has four levels and five factors was used to prepare the mix proportions. The result showed that Optimum conditions for maximum modulus of elasticity were obtained at lower water/cement ratios and recycled aggregates with values ranging between 35.89-41.26 Gpa. The Taguchi experimental approach is a good tool for obtaining optimum conditions in experiment involving many factors.
