Environment, execution, waste, concrete, constructionAbstract
The aim of this work is to assess the environmental aspects arising during the execution phase of building construction and to analyse the possibilities of reducing the negative impacts. We have studied the environmental factors associated with the use and handling of the materials, focusing the research on two of the most qualitatively significant processes: operations to clean the works and the recovery of concrete-washing water. In both cases, a qualitative analysis of environmental impact has been made. In the wash-water study, basic parameters (density by differential weighing, pH by pHmeter and chemical composition by X ray fluorescence) of ten samples were analysed to evaluate the quality of the discharges and thus be able to propose solutions and technological improvements (filtering, neutralization,…) applicable to construction works with the aim of decreasing the volume of dislodged solids and improve the quality of water discharged.
