EVALUATION OF CO₂ EMISSION FROM CONSTRUCTION OF MICROPILE METHOD USING PRECAST CONCRETE MEMBER

Abstract

The purpose of the present study is to evaluate quantitatively CO₂ emission from micro pile method using pre-cast concrete member. This paper describes CO₂ emission by using typical models of L-shaped retaining wall and box culvert, which often employ pre-cast concrete member. Additionally, the authors estimated CO₂ emission of an actual pre-cast box culvert for micro pile construction as comparing with cast-in-place concrete. As these results, the micro pile method with pre-cast concrete indicated higher effectiveness of CO₂ emission reduction than normal construction.
