Although recycling and re-use are good alternatives to waste disposal, in Europe and the USA, for example, only 30% of the total CDW volume is consigned to recycling [13].This rate is even lower in some countries, such as China (5%) [7] and Portugal (9%) [14].In Brazil, a survey carried out in 2011 showed that CDW recycling plants operating at maximum capacity …

It is an inevitable trend to recycle and use construction waste. Recycled aggregate concrete (RAC) has been widely studied and put into use. However, it is an important issue to improve the utilization rate and sustainability of waste concrete that how to use RAC for generations and apply it in a durable environment (freezing and thawing, carbonation, chloride …

1. Introduction. The incorporation of recycled aggregates (RAs) in concrete contributes to the European Union's (EU) goal of 70% of non-hazardous construction and demolition waste (CDW) reuse/recycling, defined in EU Directive 2008/98/CE [].The technical feasibility of recycled aggregate concrete (RAC) has been demonstrated in several previous …

On the other hand, pervious concrete has been developed toward eco-friendly materials with sustainable development [17], and the increasing strictness of regulations of quarrying, resulting in recycled aggregates as a substitute for traditional coarse aggregate, has been widely recognized as a potentially suitable alternative [18], [19], [20].

Recycled Coarse Aggregate (RCA) The RA was sourced from a wrecked residential structure in Chennai's West Mambalam. The aggregate obtained had a specific gravity value of 2.78 and was crushed to the necessary particle size of 10–20 mm. RA is created by crushing and sorting construction waste, such as concrete, brick, and asphalt, into sizes ...

The 28-day compressive strength of polystyrene concrete increased from 5.6 MPa to 11.9 MPa when the w/c decreased from 0.60 to 0.35. The compressive strength of LWC was shown to be more sensitive ...

Barriers and lessons learnt: The management of the facility faced many barriers in the C&D waste recycling process as well as in the sale of recycled products.The market acceptance of the recycled aggregates was also low. Hence various value-added products were produced and sold as a finished product instead of selling as a raw material.

Results and conclusion: This paper presents and analyses innovative LCA data of production of coarse aggregates, both natural and recycled (from mobile or fixed recycling plants). The recycling ...

(Fine aggregate and Coarse aggregate): The natural fine aggregate used for producing concrete is m-sand. The natural coarse aggregate used is microtonalite. The maximum size of this gravel is 25 mm. The cement used is OPC 43 grade Ultra Tech. Recycled aggregate used in this research is crushed concrete, i.e. RCA obtained from a site near St.

Replacing 11.7% of the recycled coarse aggregate with natural sand and adding date palm leaves fibers in an amount equivalent to 0.64% volumetric content to such concrete helped increase the compressive strength by 16.2% and tensile strength by 3.2% above the corresponding strengths of the control mix. ... the waste at the recycling plant is ...

The use of recycled aggregate concrete in this time of modern civilization opens a whole new range of possibilities. Recycling of Concrete Debris Source- YouTube. The requirement for coarse recycled concrete aggregate (RCA) and coarse RA is specified in BS 8500-2: 2002 which is given the image below.

The use of DRCA for pavements, in addition to the sub-base and sub-grade [], could be suitable, as safety or strength is not the only criteria for the design or application.Further, the environmental impact of recycled concrete aggregates in terms of the consumption of non-renewable resources is much lower compared to NA [15, 16].Also, the use of supplementary …

As part of efforts to attain circularity in the concrete industry, there is growing interest in employing Recycled Coarse Aggregates (RCA) in commercial concrete production (Wijayasundara et al., 2018).This shift is primarily motivated by the urgent need to address the environmental impacts and the depletion of resources linked to the use of Natural Coarse …
