Eco-concrete. Eco-concrete is defined as concrete with at least 50% by mass of total aggregate content replaced by recycled materials, used for non-structural applications. Typical materials used for aggregate replacement include washed copper slag or recycled aggregates or a combination of both.
To align with Singapore’s vision in construction sustainability, Eastern Continent also recycle concrete debris from demolishing works and convert them into useable products as Recycled Concrete Aggregate (RCA).
Recycled concrete aggregate (RCA) are aggregates obtained by recycling clean concrete waste where content of other building waste must be very low – below few per cent.
According to a 2004 FHWA study, 38 states recycle concrete as an aggregate base; 11 recycle it into new portland cement concrete. The states that do use recycled concrete aggregate (RCA) in new concrete report that concrete with RCA performs equal to concrete with natural aggregates.
Aug 1, 2021 · Using recycled aggregate s from construction and demolition waste can preserve natural aggregate resources, reduce demand of landfill, and contribute to sustainable built environment.
Mar 29, 2013 · By collecting the used concrete and breaking it up, recycled concrete aggregate (RCA) is created (Fig. 1 ). This paper focuses on coarse RCA which is the coarse aggregate from the original concrete that is created after the mortar is separated from the rock which is reused.
Oct 28, 2021 · In this paper, a comprehensive literature review was conducted on the utilization of recycled concrete aggregate (RCA), which is the dominant construction and demolition waste material, in base and subbase layers and its comparison with natural aggregate (NA).
Sep 1, 2023 · Recycled concrete aggregates. Sustainability. Engineering properties. Life cycle assessment. RCA inclusion and recovery. 1. Introduction. Globally, the unabated extraction of natural resources without recourse to a circular economy has wreaked havoc on the environment.
Aug 10, 2023 · This article presents a comprehensive review on the use of recycled concrete aggregate (RCA) and recycled aggregate concrete (RAC) in construction, with emphasis on structural applications and identification of challenges and opportunities of RCA/RAC materials in Southeast Asia.
