  Empirical Model Relativity of Flexural and Compressive Strength of Concrete Produced with Foundry Waste Sand as Partial Replacement

  By C. Ukpaka, G. C. Jula

  Abstract: The evaluation presented in this research is to establish the correlation between compressive strength of concrete and flexural strength of concrete of grade 20 at mix ratio of 1:2:4 produced using foundry waste sand as a partial replacement for river sand at different replacement level of 0%, 5%, 10%, 15%, 20% and 25%. The aimed compressive strength was achieved at 15% replacement and the corresponding flexural strength of 3.14 N/mm2was …
