Material Reuse

Purpose The purpose of this paper is to explore the intersection of building material reuse and heritage value, and raises questions about how “preservation” has traditionally been defined and conceptualized. With a grounding in the realities of global climate change, the paper argues for further research on the topic and for the active engagement of the preservation field in reuse efforts. Design/methodology/approach After a review of existing literature, this study takes a descriptive and conceptual approach to explore the heritage values generated through material reuse. Findings This paper finds that processes of material reuse are richly embedded with heritage value and offer a conceptual challenge to established modes of heritage practice. Practical implications The findings of this paper suggest that heritage practitioners should actively engage with material reuse efforts to better understand the heritage values generated from such processes. Areas of future research and collaboration are identified. Originality/value Despite their intrinsic interaction with aged and existing infrastructure, there has been limited engagement in the heritage and preservation field with the topics of deconstruction, building material reuse, or construction and demolition waste practices more generally. This paper thus provides descriptive research on a topic that has been unevenly explored.

The Relationship

<p>Following the 2010 and 2011 Canterbury earthquakes, earthquake strengthening is one of the biggest issues facing heritage buildings in New Zealand. This process is mainly affecting commercial and public buildings; residential buildings are generally exempt from earthquake-prone building policies. However, some homeowners are choosing to do what is often perceived to be an expensive and time-consuming process. This research explores whether there is a heritage relationship between the homeowner and their house that motivates conservation work, such as earthquake strengthening. The central question for this research is: “What makes a heritage house a home? Is “home” a motivation for owners to earthquake strengthen their building? a case study of Dunedin”.  The relationship between homeowners and the heritage of their homes and domestic conservations practices has been underexamined in heritage studies in New Zealand. The current dissertation addresses this problem and contributes to the literature of Museum and Heritage Studies. The theoretical framework employed in this research draws on the field of Critical Heritage Studies in order to explore the relationship between ‘top-down’ and ‘bottom-up heritage’, the notion of ‘peoples-based’ heritage, the value of intangible heritage and a cycle of care. This research utilised qualitative research methods, involving the interviewing three heritage homeowners and two heritage professionals. These provided detailed findings about homeowners’ perceptions of their houses and the interaction between heritage practitioners and homeowners. The southern city of Dunedin was the case study which framed this research, because it has a rich collection of heritage buildings and a council which has been proactive in encouraging earthquake strengthening.  It was found that the heritage homeowner’s relationship with their home played a role in conservation how decisions are undertaken and that there is a lack of outreach from heritage authorities to heritage homeowners. This research provides information about the nature of the interaction between top-down and bottom-up heritage, and how this relationship can lead to positive heritage outcomes. Recommendations include developing open channels of communication between officials and homeowners, increased acknowledgement of the homeowner’s role in the conservation practice, and the establishment of a concept of Domestic Heritage to assist within the development of a cycle of care by heritage homeowners.</p>

Purpose The purpose of this paper is to investigate the potential use of construction and demolition waste materials (C&DWM) as an alternative for natural fine aggregates (NFA), in view to solve the disposal problems caused due to landfills. In addition, to evaluate its suitability as a sustainable material, mechanical and durability properties have been performed on different proportions of concrete blending and the results recorded were compared with the reference concrete values. Design/methodology/approach In this research, the NFA were replaced at the proportion of 25%, 50%, 75% and 100% of C&DWM with a constant slump range of 130 mm–150 mm. This parameter will assess the consistency of the fresh concrete during transportation process. The characteristics of the end product was evaluated through various tests conducted on hardened concrete samples, namely, compressive strength, flexural strength, depth of penetration of water under pressure, rapid chloride penetration test, carbonation test and ultrasonic pulse velocity (UPV) test. All results recorded were compared with the reference concrete values. Findings The results demonstrated that the use of C&DWM in concrete portrayed prospective characteristics that could eventually change the concept of sustainable concrete. It was noted that the compressive and flexural strength decreased with the addition of C&DWM, but nevertheless, a continuous increase in strength was observed with an increase in curing period. Moreover, the increase in rapid chloride penetration and decrease in UPV over time period suggested that the concrete structure has improved in terms of compactness, thus giving rise to a less permeable concrete. The mechanical tests showed little discrepancies in the final results when compared to reference concrete. Therefore, it is opined that C&DWM can be used effectively in concrete. Originality/value This study explores the possible utilisation of C&DWM as a suitable surrogative materials in concrete in a practical perspective, where the slump parameter will be kept constant throughout the experimental process. Moreover, research on this method is very limited and is yet to be elaborated in-depth. This approach will encourage the use of C&DWM in the construction sector and in the same time minimise the disposal problems caused due to in landfills.

Waste from the construction sector poses huge challenges for sustainable waste management. This is not only due to the vast amount of waste produced in construction and demolition activities, but also due to pollutants potentially contained in these products. Subject to these conditions, waste management must ensure recovery of as many resources as possible, while making sure to keep material loops clean. This demanding task requires more knowledge about the existing building stock and an adaptation of current demolition processes. Innovative technologies, such as Building Information Modelling, or modern frameworks, such as Geographic Information Systems, offer a high potential to synoptically provide stock material information for future demolition activities for individual objects to be deconstructed as well as for whole cities as a basis for managing the anthropogenic stock and potential urban mining. Suitable methods of data collection allow for acquiring the desired input for the generation of building stock models enriched with demolition-related information. With the latter, selective deconstruction strategies as well as appropriate waste stream routing agendas can be planned and executed, thereby securing safety at work during the demolition process itself and a waste stream routing according to the waste hierarchy. This review article gives an overview of currently deployed building material assessment tools (data capture and visualisation), both a prerequisite for improved information on materials and geometry (and thereby mass/volume). In addition, this article describes workflows employable for the purpose of urban mining in end-of-life buildings, of which one holistic approach will be described in depth.

The world’s demand for construction aggregates has been increasing over the last years, mainly due to the rapid economic growth of countries such as Brazil, China and India. Naturally, this growth stimulates the development of construction and demolition activities, thereby generating increasing amounts of waste. This paper presents a state-of-the-art review of the experimental research on the effect of incorporating aggregates of different types and shapes, sourced from construction and demolition waste. This review also covers studies on the incorporation of waste materials coming from industrial activities, emphasising those performed in the Instituto Superior Técnico, of the University of Lisbon, Portugal.
