  • The purpose of this experimental research is to investigate the mechanical properties of ordinary strength and high strength concrete containing waste glass powder. For this purpose, after production of concrete containing waste glass powder for different unit weight of binder and placement ratio of waste glass powder, optimum mixing proportions of them was determined, and then mechanical properties such as static modulus of elasticity as well as compressive, tensile and flexural strength were tested and analyzed for concrete produced according to optimum mixing proportions. As a result, the concrete containing waste glass powder has as excellent workability and strength, it's strengths are analogus to those of silica fume, it's workability is somewhat better than that of silica fume.

  • The present age, it has been often reported that recycling of wasted glasses should be a great topic in related business circles. For the enviromental reasons, a public institution are looking for the ways of recycling these waste glasses. Consequently, the purpose of this research is to recycle crushed and powdered waste glasses by substituting for the cement in mortar and concrete. First of all, the optimum replacement ratio of Powdered Waste Glasses(PWG) can be obtained from the pilot test results. Secondary, we make advances in recycling of waste glasses as recycled to make secondary concrete products. So, we manufactured concrete brick and block contained powdered waste glasses by through mortar pilot test.

  • Due to the economic growth and the improvement of life standards in the country, the quantities of waste glasses have been yearly increased. About 65% of them are recycled and the rest are reclaimed. The reclaimed waste glasses can cause some problems such as the environmental pollution as well as the processing cost of them. Thus, the purpose of this experimental research is to investigate the properties of mortar using powdered waste glasses(PWG) as a cementitious materials in mortar to recycle the reclaimed waste glasses For this purpose, the workability and strength of mortar specimens using PWG have been tested and analyzed in various grain size of them by changing the replacement ratio. As a result, considering the workability and strength of mortar specimens using PWG, it is concluded that the optimum grain size and replacement ratio of them will be existing.

  • 삼척 도계지역의 탄광에서 석탄채취 시에 부산물로 발생되는 석탄폐석을 원료로 하여 제조된 분말유리와 다양한 종류의 발포제를 활용하여 발포유리를 제조하였다. 유리는 소다라임계 화학조성을 갖는 유리였고, 유리분말에 발포제로서 탄산칼슘, 인산칼슘, 그리고 석탄폐석 중 카본함량이 높은 셰일(shale) 계의 석탄폐석분말을 사용하였고, 이들 원료에 액상 바인더를 첨가하여 혼합한 후, 판상의 형태로 성형하였다. 성형체를 건조한 후 전기로에서 $800^{\circ}C$ 20분간 열처리함으로써 다공성의 발포유리 패널을 제조할 수 있었다. 발포제의 종류에 따라 다양한 특성을 갖는 발포유리샘플이 제조되었으며, 이들의 비중 및 압축강도와 같은 물리적 특성을 측정하였고, 기공의 크기 및 형태를 현미경으로 관찰하였다. 석탄폐석으로 제조한 폐유리를 활용하여 비중 0.4~0.7, 압축강도 30~72 kg/$cm^2$를 갖는 발포유리 샘플을 얻을 수 있었으며, 특히 액체인산 칼슘 발포제를 사용하여 0.47의 낮은 비중과 72 kg/$cm^2$의 높은 압축강도를 갖는 발포유리를 얻을 수 있었다. 따라서 삼척지역에 폐기된 다량의 석탄폐석이 건축용 및 산업용 발포유리 2차 제품을 제조하는데 충분히 활용이 가능하리라 판단되었다.

  • This study was performed to evaluate the void ratio, compressive and flexural strength, and permeability coefficient used powdered waste glass, $CaCO_3$, recycled coarse aggregate and unsaturated polyester resin to find optimum mix design of permeable polymer concrete for pavement. The void ratio and permeability coefficient of permeable concrete for pavement was decreased with increasing the powdered waste glass, respectively. The compressive strength and flexural strength was increased with increasing the powdered waste glass, respectively. In addition, this study found out that required amount of binder was decreased with increasing the powdered waste glass. This fact is expected to have economical effects during the use of powdered waste glass in the manufacture of permeable polymer concrete for pavement. Therefore, powdered waste glass and recycled coarse aggregate can be used for permeable polymer pavement.

The compressive and flexural strength of permeable polymer concrete for pavement using powdered waste glass were in the range of 16.8~19.7 MPa and 4.7~6.1 MPa, respectively. it was satisfied the regulation of permeable concrete for pavement (18 MPa and 4.5 MPa). The void ratio and permeability coefficient were decreased with increasing the powdered waste glass, respectively. The void ratio and permeability coefficient were satisfied national regulation of permeable concrete for pavement (8 % and $1{\times}10^{-2}$ cm/s). In addition, this study found out that required amount of binder was decreased with increasing the powdered waste glass. This fact is expected to have economical effects during the use of powdered waste glass in the manufacture of permeable polymer concrete for pavement.
