Study of Parameters Contributing to the Environmental Impact in Precast Concrete Production
Like most other industrial manufacturing process, the production of concrete implies emissions to the atmosphere which consist of the emissions ffom the manufacturing of raw materials, transportation, construction, maintenance, demolition and also disposal and recycling process at the end of its life. This paper considers a few parameters that contribute to the emissions in precast concrete production, i.e. electricity consumption, fuel consumption for boiler steam curing, diesel consumption for forklift, and kerosene consumption for jet heater. The amount of emissions emitted from waste concrete treatment is also being considered in this paper. The data involved were obtained fiom 2007-2008 report of precast concrete production in 9 plants around Chugoku area in Japan under one company. The result shows that type of machine, degree of efficiency, type of fuel and method of curing are some of the contributing factors to the differences in the amounts of emissions in precast concrete production.
