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, yield point and maximum load decreased with decreasing concrete strength and elastic modulus. Also, the finite element analysis program does not reflect the ductility loss of RC members using heavy weight waste glass as fine aggregate.

In this paper, the flexural test of concrete member damaged due to Calcium leaching were performed to evaluate the characteristics of structural behavior. From the results, yield load, maximum load and flexural rigidity of RC member damaged by calcium leaching were decreased and the depth of the neutral axis was increased.

It is necessary to investigate the possibility of high density material as an ingredient in the manufacturing of radiation shielding material. In this study, the suitability of heavy weight waste glass as a shielding material is considered. From the results, it was found that when the heavy weight waste glass substitution ratio increases, radiation shielding performance also increase.

Electrical waste, such as heavy weight waste glass, has become a global concern in terms of resource recycling. At the same time, aggregate is one of the most widely used infrastructure materials, and it is being exhausted. So, in this paper, the heavy weight waste glass is considered as aggregate due to its physical characteristics and chemical composition. From the results, when the heavy weight waste glass substitution ratio increase, the compressive strength and flexural strength decreased.

In this paper, the sulfate resistance of concrete substituted the crushed heavy weight waste glass as fine aggregate are compared and evaluated. From the results, when heavy weight waste glass substituted ratio increase, the reduction rate of compressive strength is decreased. So, the sulfate resistance is improved by using heavy weight waste glass in concrete.
