Fine Aggregates of CDW: Feasibility of Its Application in the Manufacture of Mortars for Laying

Abstract

One of the problems faced by the sector of civil construction currently is related to the difficulty to obtain environmental licenses for the extraction of natural aggregates, in due to the environmental impacts caused by such activity. The objective of this study is to propose the replacement of natural sand and gravel with aggregates of construction and demolition waste (CDW) in the production of mortar for laying. For the characterization of the mortars were determinate the consistency index, water retention, specific gravity, tensile strength in flexion and compressive strength. The CDW fine aggregates replaced the natural sand, in mixtures of mortar without to prejudice mortar properties. (c) 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
