Prediction of the compressive strength of concrete made by recycled coarse aggregate derived from selective demolition

The utilization of Recycled Coarse Aggregate (RCA) in concrete has gained signifi-cant traction due to its environmental and economic advantages. However, ensuring the quality of RCA poses challenges as it is influenced by various unpredictable factors includ-ing the high water absorption of RCA, ineffective recycling processes, and the presence...

A predictive model of concrete compressive strength based on level of contamination of coarse aggregate: Experimental study and relation to the water absorption of the coarse aggregate

Recycled aggregate concrete is emphasized more and more nowadays due to its importance towards the construction industry and general welfare of our planet. Being such a significant feature with regard to universal sustainable development, every aspect of its properties should be evaluated, examined and optimized so that there is a well-known,...

Explorative case study to gain insight on the consequences of circular infrastructural construction projects: Investigating the effects of circularity in construction projects on project process and construction costs.

The aim of this research was to investigate the effects of implementing circularity in infrastructural construction projects. As a very polluting sector, circularity is becoming a more and more popular theme in the construction industry. Driven by both governmental regulations of reaching a full circular economy in 2050 and intrinsic motivation,...

The future of concrete recycling: An integrated life cycle environmental and cost analysis on the hotspots to improve the demolition and recycling practices across Europe

Building construction is a material-intensive process known for depleting natural resources, mainly gravel and sand, used in concrete production. At the same time, building demolition generates large amounts of construction and demolition waste (CDW), primarily consisting of end-of-life (EOL) concrete, a significant waste flow occurring in...

Circular Economy Evaluation of Urban Railway Infrastructure

The European construction sector is responsible for the consumption of almost 32% of total raw material for realizing its projects (Benachio, Freitas, & Tavares , 2020). On a national level, this amount results to almost 50% for the Dutch construction industry (Nellssen, et al., 2018). The ever-growing population stresses the need for...
