| 要旨 |
As one of the approaches to promote the reduction of environmental load in concrete and concrete structure in general, this paper aims to estimate the amount of emissions (CO2, SOx, NOx and PM) as results of waste concrete treatment in precast concrete production by using the emission inventory data and also to propose a better approach regarding to this matter. Surveys to some plants were made to investigate the real situation of its application. It was found that small-sized products plants produced the highest emissions per ton of concrete compared with other types of plants. |
