Ecotoxicity and Essential Properties of Fine-Recycled Aggregate. [PDF]

open access: yesMaterials (Basel), 2021
This article deals with the possibility of utilization of secondary-raw materials as a natural sand replacement in concrete. Four types of waste construction materials were examined—recycled aggregate from four different sources. The natural aggregate was examined as well as used as the reference sample.

Properties of concrete incorporating fine recycled aggregate

open access: yesCement and Concrete Research, 2005
Abstract The properties of concrete containing fine recycled aggregate are investigated. Recycled aggregate consisted of crushed concrete (CC) or crushed brick (CB) with particles less than 5 mm in diameter. The free water/cement ratio was kept constant for all mixes.

Enhancing the Mechanical and Durability Properties of Fully Recycled Aggregate Concrete Using Carbonated Recycled Fine Aggregates

open access: yesMaterials
The global construction industry is increasingly utilizing concrete prepared from recycled aggregate as a substitute for natural aggregate. However, the subpar performance of recycled fine aggregate (RFA) has resulted in its underutilization, particularly in the structural concrete exposed to challenging environments, including those involving chlorine

The Durability of Recycled Fine Aggregate Concrete: A Review [PDF]

open access: yesMaterials, 2022
With the rapid development of urbanization, many new buildings are erected, and old ones are demolished and/or recycled. Thus, the reuse of building materials and improvements in reuse efficiency have become hot research topics. In recent years, scholars around the world have worked on improving recycle aggregates in concrete and broadening the scope ...

Nanostructure of calcium-silicate-hydrates in fine recycled aggregate concrete

open access: yesCement and Concrete Composites, 2021
Our research objective is to foster a multiscale understanding of fine recycled aggregate concrete using a bottom-up approach. We investigate the influence of fine recycled concrete aggregates on the structure of calcium-silicate-hydrates.

Steel fibre-reinforced concrete with fully recycled coarse and partially recycled fine aggregates [PDF]

open access: yesScientific Reports
The construction industry is showing an increasing interest in the integration of Recycled Aggregate (RA) into concrete as a substitute for natural coarse aggregate, whether in full or in part, with the aim of reducing dependence on virgin aggregate ...

The Durability of Fine Recycled Aggregate Concrete

open access: yesAdvanced Materials Research, 2017
This paper is focused on the durability of recycled aggregate (FRA) concrete. The durability of FRA concrete is connected with many uncertainties and doubts. This paper presents results of long-term of compressive strength, freeze – thaw resistance and carbonation depth of FRA concrete. The FRA was originated from crushed old concrete structures. There

Use of recycled fine aggregate in concretes with durable requirements

open access: yesWaste Management, 2011
The use of construction waste materials as aggregates for concrete production is highly attractive compared to the use of non-renewable natural resources, promoting environmental protection and allowing the development of a new raw material. Several countries have recommendations for the use of recycled coarse aggregate in structural concrete, whereas ...

Influence of Accelerated Carbonation on the Performance of Recycled Concrete Containing Fly Ash, Recycled Coarse Aggregate, and Fine Aggregate

open access: yesMaterials
In order to improve the quality of solid waste utilization, this study simultaneously used recycled coarse aggregate and recycled fine aggregate to prepare recycled aggregate concrete, with fly ash partially replacing cement as a binder.
