In this paper, the flexural behavior of RC member recycled heavy weight waste glass as fine aggregate was evaluated by finite element analysis. From the results, the analytical results do not reflect the experimental results. This is because the stress-strain curve of the concrete specimen obtained from the compression test was used as the input data for the ABAQUS. Therefore, the ABAQUS, based on the experimental results of the stress-strain relationship of concrete, predicted the load-displacement relationship without considering the reduction in load capacity.

The heavyweight industrial waste was used as concrete ingredient instead of natural aggregate, however, design standard did not consider effects of heavyweight aggregate on flexural strength. Therefore, in this paper, correlation between compressive and flexural strength of concrete using industrial was compared. From the results, compressive strength and flexural strength decreased with industrial waste increasing. And, it was shown that the test results of flexural strength were higher than the predicted value from design standard.

In this study, the properties of mortar substituted heavyweight waste glass were evaluated. From the results, the flow value and density increased as the substitution ratio of heavyweight waste glass increased, and compressive and flexural strength decreased.

In this study, the characteristics of density and flow value of mortar substituted heavy weight waste glass were compared with the aggregate ratio. From the results, the density and flow value increase as the substitution of waste glass increase, however, it is considered that the increase of the aggregate ratio of 30% or more does not contribute to the increase of the density.

Recently, the industrial waste resources have been continually developed because of a lack of natural aggregate. In this study, before the applicability of concrete using steel slag as aggregate, the properties were evaluated. From the test results, it is showed that the water aging period of the steel slag had no effect on the air contents, slump, compressive strength and density.
