Description:
An experimental study has been executed to optimize concrete for prefabrication of concrete elements by realizing an early age strength comparable with the reference concrete 100% Ordinary Portland Cement (OPC) and by minimizing the environmental impact. The environmental impact is quantified with two parameters: the emission of CO2 per volume of concrete and an environmental cost indicator, which comprises eleven effects on the environment. The Dutch CUR tool ‘Groen Beton 3.2’ was used as a source for the calculations with regard to the environmental impact; the background of the environmental cost indicator is elaborated. The study comprises an initial mortar-based study to determine strength levels and environmental impact. At a comparable workability level, specimens were produced of which the compressive and flexural strengths were determined at different ages after casting. For selected mixtures differences in the heat of hydration were assessed and the mix design was transferred to concrete. The results show that concrete elements can be produced with a much lower impact on the environment and without compromising on the production conditions.
