The rheological behavior of a cordierite honeycomb extrusion paste was investigated by measuring torque values in a Brabender plastograph. The extrusion pastes were formulated using binder (methy cellulose, MC), solvent (water), plasticizer (ploy ethylene glycol, PEG) and lubricants (oleic acid, OA). The mixing sequence and optimum organic binder, at least for homogeneous mixed state, can be determined from the rheological point of view. 3%MC-30%-1.5%PEG-1.0%OA with respect to the cordierite powder was chosen as a binder composition for the extrusion process of cordierite powder.

To repair pothole failure in asphalt pavement, this study is developing high durability rehabilitation method using construction equipment and pre-cast material. The various filling material was examined to bond pre-cast repair material at asphalt pavement, performance was evaluated throuth tensile bond and shear bond test. As a result, Guss asphalt binder and two-component polyurethane material was shown a superior performance in terms of tensile bond strength, shear bond strength was two-component polyurethane material to be effective.

천마음료를 제조시 첨가물로 천마 추출액을 달리하여 제조한 pH, 당도, 색도, 총페놀 함량, DPPH radical 소거 활성능, 유리당, 유기산 및 유리아미노산 함량, 무기질 함량, 관능 검사를 분석하여 품질 특성을 검토하였다. 천마음료 제조 시 GCE 5(Brix 천마 농축 추출액), GCE 10(Brix 천마 농축 추출액), GCE 15(Brix 천마 농축 추출액), GCE 20(Brix 천마 농축 추출액)으로 나누어서 제조하였다. pH는
