Durability of crushed fine recycled aggregate concrete assessed by permeability-related properties

Magazine of Concrete Research, 2019
One of the paths taken towards the greening of concrete has been through the use of recycled aggregates as replacement of their natural counterparts.

Application of ferronickel slag as fine aggregate in recycled aggregate concrete and the effects on transport properties

Journal of Cleaner Production, 2021
Industrial and construction solid waste regarded as a hazardous material has given rise to the potential threats of environmental pollution. The ferronickel slag (FNS) as an industrial by-product and recycled concrete aggregates (RCAs) derived from ...

Recycling of PET bottles as fine aggregate in concrete

Waste Management, 2010
An attempt to substitute in concrete the 5% by weight of fine aggregate (natural sand) with an equal weight of PET aggregates manufactured from the waste un-washed PET bottles (WPET), is presented. The WPET particles possessed a granulometry similar to that of the substituted sand.

Research on Properties of Recycled Fine Aggregate from Waste Recycled Aggregates Concrete

Advanced Materials Research, 2011
The properties of recycled fine aggregate(RFA) from waste recycled aggregate concrete (RAC) were determined. In this study, five series of parental concrete mixtures using natural coarse and fine aggregates were prepared, which had the same target slump value from 35mm to 50mm and different compressive strengths ranging from 25MPa to 60 MPa.

Pycnometry for assessing porosity of fine recycled aggregates

Construction and Building Materials, 2021
Abstract The study extended the applications of powder pycnometry (PP) replacing the commercial enveloper for alternative envelopers (ceramic and carbon microspheres) to determine the envelope density of fine recycled aggregates (FRA) sand fraction.

Recycled ceramic fine aggregate for masonry mortar production

Proceedings of the Institution of Civil Engineers - Construction Materials, 2017
Construction and demolition waste is composed of fragments of ceramic tiles, steel, wood, plaster, glass, concrete and mortar. Reduction and reuse of this waste can minimise the consumption of natural resources and energy in the construction industry. In addition, high population growth followed by a large housing deficit in many countries highlights ...

Concrete with Recycled Glass as Fine Aggregates

ACI Materials Journal, 2014
Recycled waste glasses were used as sand replacement in concrete at 0, 25, 50, 75, and 100% replacement ratios. Diverse concrete properties were tested in fresh and hardened states with three concrete grades; that is, with compressive strengths of 30, 45, and 60 MPa (4350, 6525, and 8700 psi).

Durability studies on recycled fine aggregate concrete

Construction and Building Materials, 2020
Abstract The use of recycled fine aggregates (RFA) from construction and demolition(C&D) waste in concrete gaining importance from past decades. The presence of excessive fines and old adhered mortar in RFA, make mediocre properties of RFA concrete.
