Comparative LCA of concrete with recycled aggregates: a ...
Life cycle assessment (LCA) methodology is applied using Simapro© software. A cradle to grave analysis is carried out. The results are analysed based on the database Ecoinvent 3.3 and Impact 2002+. Results show that the concrete with 25% recycled aggregates is the best solution from an environmental point of view.Learn More
Life Cycle Assessment of Completely Recyclable Concrete
Mineral demolition waste can be recycled as crushed aggregates for concrete, but these reduce the compressive strength and affect the workability due to higher values of water absorption. To advance the use of concrete rubble, Completely Recyclable Concrete (CRC) is designed for reincarnation within the cement production, following the Cradle-to-Cradle (C2C) principle.Learn More
A review of life cycle assessment of recycled aggregate concrete
Jun 10, 2019 · Recycled aggregate has emerged expecting to address raw materials shortage in construction sector by converting waste concrete into resource. Many researchers adopted life cycle assessment (LCA) to evaluate and compare environmental impact of recycled aggregate concrete (RAC) and natural aggregate concrete (NAC).Learn More
LCA of concrete with construction and demolition waste ...
Jan 01, 2020 · This study deals with the life-cycle assessment (LCA) of concrete production process. Concrete mixtures prepared with construction and demolition waste (CDW) at different percentages (10%, 40%, 80%, and 100%) are investigated to compare the environmental and energy impacts related to their production with mixtures made of natural aggregates.Learn More
Environmental life cycle assessment of coarse natural and ...
Purpose: To present a comparative life cycle assessment (LCA) of natural and recycled coarse aggregates used in concrete production. Methods: LCA was used to compare the environmental impacts of three alternative of procurement of coarse aggregates for concrete production: extraction and processing of natural aggregates; recycling of demolished concrete either using a fixed or a mobile plant. Site-specific data supplied by companies were used to model the life cycle of these aggregates.Learn More

Analysis of Life Cycle Environmental Impact of Recycled Aggregate
concrete made of waste materials by using LCA. Environmental performances of natural formulation with the same mechanical strength regarding the functional unit, were evaluated.Learn More
lca for recycling concrete - ESG Properties
Integrated life cycle assessment and life cycle costing of concrete recycling in the Netherlands. Integrating life cycle assessment (LCA) with life cycle costing (LCC) offers the opportunity to simultaneously analyze the environmental and economic aspects of product alternatives, for the integration of which a unified computational has been proposed by Heijungs et al. (2013) .Learn More
Life Cycle Assessment of Aggregates
The objective of the work reported here was to develop a Life Cycle Inventory (LCI) and Assessment (LCA) Model for the aggregates industries. The work includes the extraction and processing of primary resources through to the point of their dispatch as aggregates (including overburden stripping, drilling and blasting, and restoration), and comparing with the processing of equivalent recycled aggregates for three grades (aggregates for unbound applications; aggregates for concrete; aggregates ...Learn More
Life cycle analysis of recycled concrete | Concrete Recycling ...
The aim of this study is to confirm the eco-respectability of recycled aggregates concrete (RAC). Comparisons are performed according to the normative criteria of Life Cycle Assessment (LCA) methodology applied to construction materials (EN 15804 standard).Learn More
