Impulse response modelling on strength of eco friendly concrete infused with industrial fine aggregate wastes

Abstract

In all walks of life, one or the way, development of infrastructure plays the role of a determinant that decides upon the matrix of our lifestyle. By this token, concrete has become an essential construction compound assuming inevitably alarming proportions as the primary need in sustaining development activities hitherto and in future too. However, by resorting to unscrupulous mining and quarry aspects to get the necessary building materials and the ingredients for a concrete mix, we have landed in a precarious situation of depletion of these non-renewable resources including water. With a futuristic prediction, for an imbalance between demand and supply of the building materials, disturbing the sustainability of construction activities conceptual changes towards partial substitution of total replacement by test verified similar materials with the common ingredients of concrete. Including the possible switching over to treated wastewater in place of costlier potable water, have been gaining momentum and popularity. The suitable alternative materials for the cementitious portions may be either fly ash or GGBS. For the filler portion, the fine aggregates in the conventional form of river sand can be substituted with quarry dust or foundry sand or industrial fine aggregate wastes from refractory while steel slag residues can replace the coarse aggregate mantle. newline newline newline
