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.

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.

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.

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.

급격한 산업화와 삶의 질의 변화로 인해 생산된 고밀도 폐유리의 양은 꾸준히 증가하고 있으나 대부분 재활용되지 못하고 있다. 특히 고밀도 폐유리의 경우 불법적으로 처리되거나 매립되는 실정이다. 한편, 원전구조물의 안전성 확보를 위해 차폐 성능이 우수한 재료가 사회적으로 요구되고 있다. 콘크리트는 가장 많이 사용되고 있는 건설재료이며, 많은 양의 자원들이 콘크리트를 생산하기 위해 사용되고 있다. 따라서 고밀도 폐유리를 차폐 콘크리트 재료로 재활용할 수 있는 방안에 대한 연구가 요구되어진다. 본 연구에서는 고밀도 폐유리를 차폐 콘크리트 잔골재로의 적용가능성을 평가하였다. 결과에 따르면, 폐유리를 혼입한 모르타르의 경우, 일반 모르타르에 비하여 단위용적질량이 증가하여 차폐 성능 개선이 가능할 것으로 판단된다. 폐유리 혼입에 의해 강도는 감소하는 것으로 나타났으며, 세척의 경우보다 비세척의 경우에 강도 발현이 유리한 것으로 나타났다.

As the industrialization is rapidly growing and the quantities of heavy weight waste glass have been quickly increased but the most of them are not recycled. The heavy weight waste glass have been treated by illegal dumping or being buried in landfills. And, it is caused some problem such as the environmental pollution. So, it is needed to investigate the possibility of recycling of heavy weight waste glass as concrete material ingredient. In this paper, the mechanical properties of mortar substituted the crushed waste glass as fine aggregate are evaluated. From the results, when waste glass substitution ratio increase, fluidity and specific gravity increase. However, the compressive strength and flexural strength decrease. So, the mechanical properties of mortar are significantly affected by waste glass substitution ratio.

In this paper, the length change of mortar substituted the crushed heavy weight waste glass as fine aggregate are evaluated. From the results, when waste glass substitution ratio increase, ASR expansion increase. However, the dry shrinkage decrease. So, the length change of mortar are significantly affected by waste glass substitution ratio.

The quantities of waste glass have been progressively increased because of the rapid industrialization and quality of life. And, the most of them are not recycled. Concrete is the most widely used construction material, the huge amounts of natural resources are required to make concrete. So, it is needed to investigate the possibility of recycling of waste glass as concrete material ingredient. In this paper, the mechanical properties of mortar substituted the crushed heavy weight waste glass and p.s. ball as fine aggregate are compared and evaluated. From the results, it is concluded that the heavy weight waste glass can be used as fine aggregate of concrete.
