2018-6-27 6 Use of Recycled Aggregates in Construction 1 INTRODUCTION 1.1 General There is increasing demand and interest in aggregates from non-traditional sources such as from industrial by-products and recycled construction and demolition (CD) wastes. The American Concrete Institute (ACI)1 focuses on the removal and reuse of hardened concrete

2016-3-1 The use of recycled aggregates (RA) in construction constitutes a significant step towards a more sustainable society and also creates a new market opportunity to be exploited. In recent years, several case-studies have emerged in which RA were used in Geotechnical applications, such as filling materials and in unbound pavement layers.

2020-1-1 The use of recycled aggregate from CD wastes for base, subbase, and subgrade applications in pavement construction can have both environmental and economic benefits compared to the use of natural aggregates. Environmental impacts of recycled aggregates come from collection, sorting, reprocessing, and transportation of CD wastes.

2011-11-21 To get aggregates from recovered concrete/masonry rubbles, stratifies random sampling was used to sample the samples of rubble from the construction and demolition building as well as from the single and multi-storey buildings in Dar es Salaam city. Samples from natural source also sampled. Due to economic constraints, to get the representative samples: ten (10) samples of concrete rubble were collected from generation points and then crushed into aggregates. These samples include three (3) from multi-storey and 3 samples single storey demolished buildings; 2 samples from building construction (i.e. multi- and single storey building). Two (2) samples of coarse and fine aggregates
