Ecosystem structure diagram and emergy system diagram of multi-generation recycling of waste concrete are shown in Fig. 5 …
Concrete recycling vs concrete disposal. There are two ways to deal with old concrete: recycle it or dispose of it. Just looking at the cost to recycle concrete it is much lower than the cost to dispose of it. Recycling concrete costs around $4 -$10 per ton. Disposing of concrete can cost as much as $22-45 per ton!
The case studies used in the reliability analyses covered several design situations. A 5 mm increase of concrete cover is recommended as a simple option that ensures that the probability of ...
However, their recycling could decrease the concrete performance, particularly for low grade recycled aggregates (RA). To compensate for this decrease, cement content can be adjusted and hence, the environmental interest of RA has to be assessed. ... In this case study, and except for the water consumption indicator, it …
Cement industries generate massive amounts of greenhouse gas (GHG) emissions. As a fast-growing economy in Southeast Asia, Indonesia consumed more than 62 Mtons of cement in 2020. To cut down the impacts from extensive resource extraction and GHG emissions from cement industries, utilizing secondary raw materials such as …
The aim of the study was to demonstrate this newly introduced framework using CRC recycling as a case study. Following the framework, the recycling of CRC scrap into an industrial floor (R–CRC industrial floor) was assessed by applying in parallel life cycle assessment (LCA), life cycle costing (LCC), a social hotspot assessment, and a ...

CHALLENGES FOR THE PRACTICAL USE OF RECYCLED CONCRETE AS A SUSTAINABLE ALTERNATIVE IN CONSTRUCTION IN THE MEXICO CITY …
Furthermore, about 90% of the LCA studies on C&D waste were from European countries, the US and China (Bovea and Powell, 2016).Studies from developing countries such as India are limited and empirical data ascertaining the environmental benefits of recycling over landfilling from these regions is important owing to the …
to specific life-cycle based questions". Case studies are en-couraged to gain the experience of putting the LCS analysis in practice. 1.2 The case of concrete recycling This paper presents an on-going LCSA study for the case of concrete recycling. Construction and Demolition (C&D) waste is one of the largest solid waste streams.
Mexico is the world's largest per capita consumer of bottled water and soft drinks; both of which are contained in PET bottles. The extensive use of PET bottles in Mexico has become a severe environmental problem due to the lack of proper governmental management and public awareness. Most PET bottles end up pilled in landfills around …
Concrete waste can be generated from various activities such as construction, demolition and renovation. Instead of simply discarding this waste, it can be processed and utilised in a beneficial manner. One commonly used method for recycling concrete waste is through the process of crushing and screening [[192], [197]]. The …
Xia et al. [40] conducted a case study of a concrete structure built in Shanghai, China, using recycled aggregate concrete associated with DfD. Joensuu et al. [33] analyzed the effects of LCA ...

Concrete structures face significant challenges in sulfate-rich environments, where sulfate attack can affect their durability and structural integrity. This study explores innovative approaches to enhancing concrete performance by integrating hydrophobic and densification technologies. It emphasizes the critical role of anti-sulfate erosion inhibitors …
While concrete recycling is crucial to protecting the environment, its implementation in practice is low in many countries. This study aims to highlight …

This study assesses the environmental performance in the end-of-life (EoL) of double walls made of carbon-reinforced concrete (CRC) and steel-reinforced concrete (SRC). The most feasible CRC EoL scenarios are evaluated using life cycle assessment and their environmental performances are then compared to those of SRC. The results …
The objective of this case study is to identify the relevant processes needed in the environmental assessment of the end of life of a building and to identify the demolition process variables that significantly affect energy consumption and emissions of greenhouse gases. ...

This study forecasted the generation amount of construction waste and the carbon emission of construction waste recycling on the basis of GM (1.1) and LCA by using Shanghai City as a case study. The results show that recycling 1 t of construction waste in Shanghai can save 100.4 kg carbon emission, where concrete recycling, brick …
Downloadable (with restrictions)! Recycling of construction material helps saving the limited landfill space. Among various types of materials, concrete waste accounts for about 50% of the total waste generation. The current practice for dumping construction materials to landfills generates a significant quantity of waste from construction sites.
1. Research significance. Building and construction sector is a major contributor for CO 2 emissions, accounting for about 30% of all energy-related greenhouse gas (GHG) emissions [[1], [2], [3], [4]].Apart from that, it is responsible for about 40% of global resource use, including 12% of all fresh-water [5].Nevertheless, there is a great …
