“…MDS results show plasticizing preference; on the other hand, MDS and CBC results show a plasticizing and retarding additives preference. Due to the relation, they generate in the ease of cement mixtures and the increase in processing time, transport, and placement in the worksite (Cheung et al, 2016), (Schmidt, Alexander, & John, 2017). Conversely, there is little interest in additives related to the durability of cement mixtures in the hardened state.…”

Construction is one of the largest economic sectors due to the im pact on employment generation, trade-in materials, and development of essential infrastructure in the nations. Consequently, global economies demand to satisfy new and more significant needs. These caused by a growing population, technological development, internalization, deregulation, and market liberalization. Together, with knowledge economies related to organizational learning, business improvement, and acquisition of new methodologies, in parallel with the requirements in attractive sales costs, optimal deliveries, and better service conditions. Therefore, it's required to follow a marketing approach, together with procurement management, supported by recent production, distribution and consumption processes of materials in the construction sector, especially cement, considered as the most consumed manufactured material in the world, satisfied by the development, support and introduction of chemical additives in the technological formulations of new materials and construction processes. In consequence, the present investigation seeks to establish an understanding of markets related to the acquisition management around the commercialization of chemical additives in the construction sector of Colombia. It will be done through statistical tools of perception like Conjoint Analysis (CBC) and Multidimensional Scaling (MDS), which allow determining similarities and preferences of the users in the valuation of brands, prices, and applicability, establishing client inclinations. These use of statistical and quantitative techniques for procurement management where applicability is the attribute most desired by users related to traditional construction methods and, in turn, to some price indexes of the construction sector in Colombia.

“…At the ISEE-Africa conference 2019 [17], several workshops concluded that the label "low-cost" in this context has a negative connotation and is detrimental for the market acceptance of sustainable, materials-saving solutions. In order to avoid false public perception of environmentally friendly materials, sustainable technologies should be integrated more explicitly in curricula at universities and institutions for professional development [59].…”

Innovation potentials for construction materials with specific focus on the challenges in Africa

Africa is urgently in need of adequate basic infrastructure and housing, and it is one of the continents where massive construction activities are on the rise. There is a vast variety of potentially viable resources for sustainable construction on the continents, and consequently, the continent can bring innovative, greener technologies based on local sources effectively into practice. However, unlike established concrete constituents from industrialised countries in the global North, most of the innovation potentials from the African continent have not yet been the focus of intensive fundamental and applied research. This clearly limits the implementation of more sustainable local technologies. This paper presents a case for the need to first appreciate the rich diversity and versatility of the African continent which is often not realistically perceived and appreciated. It discusses specific innovation potentials and challenges for cementitious materials and concrete technology based on local materials derived from sources on the African continent. The unique African materials solutions are presented and discussed, from mineral binders over chemical admixtures and fibres to reinforcement and aggregates. Due to the pressing challenges faced by Africa, with regards to population growth and urbanisation, the focus is not only put on the technological (durability, robustness and safety) and environmental sustainability, but also strongly on socio-economic applicability, adaptability and scalability. This includes a review of alternative, traditional and vernacular construction technologies such as materials-saving structures that help reducing cementitious materials. Eventually, a strategic research roadmap is hypothesised that points out the most relevant potentials and research needs for quick implementation of more localised construction materials.

“…The great majority of publications found dealing with the relationship of education with CE did so in general terms and did not consider the subcategories defined for infrastructures (Bowman and Farr 2000, Russell and Stouffer 2005, Becerik-Gerber 2011, Bacon et al 2011, Bhandari et al 2011, Passow 2012, Lozano and Lozano 2014and Grigg 2018, except for a small group of publications which mainly dealt with environmental engineering in relation with sustainability (Stokes et al 1995, Henze et al 2004, Taylor et al 2007, Dimitrova 2014, Kováč and Vitková 2015, Panero et al 2018and Schmidt et al 2018).…”

While economic and environmental aspects of civil engineering have attracted the greatest attention among contemporary academy, its social side has frequently been set aside. However, the social impact that infrastructures have is huge and its analysis and understanding are fundamental. At the same time, social aspects such as culture or human behaviour can have significant effects during the different stages of the lifecycle of infrastructures. Therefore, a better understanding of the connections between civil engineering and society can help to better adapt infrastructures to their contexts, as well as minimise their negative impacts; as a result, this understanding can bring about infrastructures that are more socially sustainable.The scarce studies that have assessed the connection between society and civil engineering have considered this relationship as unidirectional. The real scenario is not so simple. The analysis of this relationship needs to be interdisciplinary, and it is in this context that this paper addresses the analysis of infrastructures and of social sciences from a sociotechnical point of view. We draw on the interrelationships found to propose a conceptual framework with the main objective of providing both practitioners and academics with tools to carry out more sustainable and context-adapted decisions. We classify the fields of civil engineering and social sciences into several different subfields, namely six for infrastructures (transport, water, energy, environment, urban planning and buildings) and twelve for social sciences (culture and history, behaviour 2 and mind, communication and interaction, socioeconomics, juridical sciences, life and health, politics, social problems, social groups, ethics and philosophy, arts and education and innovation). Afterwards, we review the existing literature at the intersection between the various categories. We conclude proposing a framework that can support decisions and actions made at different levels and working areas. The framework includes guidelines for a more holistic consideration of the interaction between infrastructures and society in key activities whereby an improved understanding of the effect of this relationship is often required. The guidelines provide a description of different key areas and can be applied to a wide variety of actions ranging from the development of university curricula to the social impact assessment of projects. education, public policy and customer privacy. Conversely, the SLCA draws from the assessment methodology developed in the context of environmental sustainability. Other approaches account for social sustainability as an integrated part together with economic and environmental factors. One example is MIVES (Integrated Value Model for Sustainability Assessment), which is a multi-criteria decision-making tool that allows to consider in a holistic way the different dimensions of a problem (Aguado et al. 2012 and) by structuring the framework into different levels, weighting each of the aspects and aggregat...
