SOLUCIONES ECOLÓGICAS Y RENTABLES PARA EL ALOJAMIENTO TEMPORAL Y LA SOLUCIÓN RURAL

Abstract

In this study, usage of silica fume, fly ash, pozzolan, marble powder, crushed glass, and ceramic as cement additive along with recycled concrete aggregate as concrete aggregate is examined. Savings of this replacement in terms of cost, CO2 emission, and waste production is computed. Concrete mix design formulae obtained by literature review with compressive strength more than 20 MPa are used. A spreadsheet application for the quantity take-off of a typical rural house and barns is prepared. Amount of reduced cement, thus CO2 emission and cost is computed by the application which makes the comparison of different mix designs feasible. Consequently, the most suitable mix design for the structure is determined. Hence buildings in the rural areas can be designed and constructed with the minimum cost and CO2 emission as well as with the maximum usage of waste materials. Similarly temporary accommodation facilities built for disaster management can also be constructed by considering the environmental criterion. This approach will also save significant amount of CO2 emission since thousands of temporary accommodation facilities are constructed after a destructive earthquake.
