TLDR
It is concluded that utilization of RAC for low-to-middle strength structural concrete and non-aggressive exposure conditions is technically feasible and the environmental impacts are slightly larger for RAC than for NAC but the total environmental impacts depend on the natural and recycled aggregates transport distances and on transport types.About:

Eco-efficient cements: Potential economically viable solutions for a low-CO2 cement-based materials industry
TL;DR: The main conclusions of an analysis of low-CO2, eco-efficient cement-based materials, carried out by a multi-stakeholder working group initiated by the United Nations Environment Program Sustainable Building and Climate Initiative (UNEP-SBCI) are presented, based on the white papers published in this special issue as discussed by the authors.

Review of LCA studies of solid waste management systems--part I: lessons learned and perspectives.
Alexis Laurent,Ioannis Bakas,Julie Clavreul,Anna Bernstad,Monia Niero,Emmanuel Gentil,Michael Zwicky Hauschild,Thomas Højlund Christensen +7 more
TL;DR: A critical review of 222 published LCA studies of SWMS found that there is little agreement in the conclusions among them and recommend stakeholders in solid waste management to regard LCA as a tool, which allows identifying critical problems and proposing improvement options adapted to the local specificities.

A review of waste products utilized as supplements to Portland cement in concrete
TL;DR: The authors summarizes the current state of practice with regard to the use of waste products as supplementary cementitious materials (SCM) in portland cement concrete (PCC) and provides a summary of the comparatively sparse information on underutilized waste materials such as: sugarcane bagasse ash, rice husk ash, waste wood biomass ash, and waste glass.

Mechanical Properties of Recycled Aggregate Concrete Under Uniaxial Loading
TL;DR: In this article, the compressive strength and the stress-strain curve (SSC) of recycled aggregate concrete (RAC) with different replacement percentages of recycled coarse aggregate (RCA) are investigated experimentally.

Mechanical behaviour of concrete made with fine recycled concrete aggregates
Luís Evangelista,J. de Brito +1 more
TL;DR: In this paper, the use of fine recycled concrete aggregates to partially or globally replace natural fine aggregates (sand) in the production of structural concrete is discussed, and the results of the following tests are reported: compressive strength, split tensile strength, modulus of elasticity and abrasion resistance.

Influence of moisture states of natural and recycled aggregates on the slump and compressive strength of concrete
TL;DR: In this article, the influence of moisture states of natural and recycled aggregates on the properties of fresh and hardened concretes was investigated, and the results suggested that an AD aggregate that contains not more than 50% recycled aggregate is optimum for producing normal strength recycled aggregate concrete.
