Recycled concrete aggregates (RCA) incorporate hydrates that can be carbonated. The FastCarb project aims to mineralize CO2 within RCA, improving the quality of these by clogging porosity and finally decreasing impact in structures. It has two main objectives: optimize laboratory conditions accelerated carbonation process which transposed at an industrial scale a suitable cost show could used conditions. This paper presents firstly results obtained conditions: it confirms is possible store...
Geopolymer-based concretes have been elaborated among others for their potential to lower the environmental impact of construction sector. The rheology and workability fresh geopolymers make them suitable new applications such as 3D printing. In this paper, we aim develop a potassium silicate- metakaolin-based geopolymer mortar with sand local earth additions suited printing an assessment framework material. methodology aims at optimization both granular skeleton matrix development...
The demolition of buildings, apart from being energy intensive and disruptive, inevitably produces construction waste (C&Dw). Unfortunately, even today, the majority this ends up underexploited not considered as valuable resources to be re-circulated into a closed/open loop process under umbrella circular economy (CE). Considering amount virgin aggregates needed in civil engineering applications, C&Dw can act sustainable catalyst towards preservation natural shift CE. This study...
ABSTRACT Calcium sulfoaluminate clinker is one of the most promising cements that would lower greenhouse gas effect accompanying cement production. This article examines gypsum content on dimensional stability mortars. Mechanical properties as chemical evolution are studied. Our results show mortar with greatest expands without a decrease its mechanical when it cured in water. Two hypotheses about mortars hydration discussed to explain differents macroscopic behaviours two
Assessing the holistic sustainability of public policies remains a challenge rarely taken up due to lack adequate assessing methods. Frequently, only environmental and/or financial aspects are addressed, rather than three pillars, including macro- and micro-economic as well social performance. This paper presents an assessment method fully compare performance pavement resurfacing for all its stakeholders considering pavement–vehicle interactions. First, analytical then systemic approach road...
Roads are major transportation infrastructure whose sustainability of maintenance practices has never been holistically assessed due to a lack proper method. This paper applies newly developed assessment method (see article part I) on 10-km-long section French highway fully compare the performance various types pavement resurfacing policies, for all stakeholders, and considering pavement–vehicle interaction (PVI). After presenting parametrization model, four alternative frequencies compared...
Abstract This paper presents a case study of environmental evaluation innovative shell-nexorade hybrid timber construction system designed within fabrication-aware technic and fabricated using robotic technology. The life cycle assessment phase the has been performed; sensitivity system’s outlay effectuated. results show that contribution to overall result is fairly significant and, in some figures, can even exceed material’s one.
Abstract Phosphogypsum (PG) is the most abundant by-product generated by phosphate fertilizer industry. Formed during production of phosphoric acid from natural rock, PG mostly disposed in stacks or released into coastal regions’ waters. Due to expected increase world – currently estimated be around 250 Mt per year and environmental impacts actual waste management scenarios, there a call for paradigm shift, considering not as but resource. About 15% total nowadays used fertilizer, retarder,...
Fabrication of a truss-like beam casted with 3D printed clay moulds Sébastien Maitenaz, Malo Charrier, Romain Mesnil, Paul Onfroy, Nicolas Metge, Adélaïde Feraille and Jean-François Caron Pages 712-716 (2021 Proceedings the 38th ISARC, Dubai, UAE, ISBN 978-952-69524-1-3, ISSN 2413-5844) Abstract: The advent reinforced concrete (RC) at beginning XXth century fostered industrialisation construction. Indeed, for first time machines such as mixers appeared on worksites. Strangely, RC...
