Use of CCW (Civil Construction Waste) in Soil Improvement

Abstract

Abstract:The vast production of CCW (Civil Construction Waste) has caused socio-environmental concern as a result of the exploration of natural resources, clandestine disposal and proliferation of vector-borne diseases, for example. It now gives priority to non-generation, reduction and recycling of CCW. This study, therefore, seeks an alternative for CCW by comparing the physical and mechanical characteristics, both in laboratory and onsite, of the recycled CCW aggregate and natural aggregate (stone powder), commonly used in the composition of compaction piles for improving soils in foundation works in the city of Recife, Pernambuco, Brazil. All results showed similar behaviours among the investigated samples (CCW recycled and natural), confirming the satisfactory performance of the investigated CCW material.
