About this ebook

Over the past few years, concrete technology has advanced quite dramatically thanks to the use of a great variety of additives and admixtures, which have paved the way for the effective development of new-generation concrete mixtures. Among these additives and admixtures, nanomaterials used in construction materials such as paste, mortar, and concrete mixtures have become very popular recently. Much of the previous attention in regard to the utilization of nanomaterials in construction materials was specifically devoted to the characterization of their fresh-state, hydration, microstructure, pore structure, mechanical, transport, and durability properties. However, research into the tailoring of multi-functional properties of construction materials (especially cementitious) with the use of nanomaterials is still in its infancy. Recent Advances in Nano-Tailored Multi-Functional Cementitious Composites aims to capture recent major scientific advances and the current state of the art in multi-functional cementitious composites developed with nanomaterials. The book will provide researchers, engineers, and other stakeholders with an insight into future directions of multi-functional capabilities of cementitious composites. Chapters focus on the large-scale development, characterization, and application of multi-functional cementitious composites addressing the following topics: nano-modified concrete; strain-hardening cementitious composites; self-sensing concrete; self-healing and bacteria-based concrete; self-cleaning concrete; self-consolidating concrete; material/construction technology for 3D printing; thermal insulation capability; green concretes including geopolymer concrete; nanoscale characterization methods; low CO2 reactive magnesia cements; and future developments and challenges of nano-tailored cementitious composites. The book will be an essential reference resource for academic and industrial researchers, materials scientists, and civil engineers working on the development and application of nano-tailored multi-functional cementitious composites. - Provides very comprehensive and unique details about multi-functional properties of cementitious composites - Presents a detailed account of investigations conducted into the application of nanomaterials and nanoscale tailoring to achieve multi-functional properties for cementitious composites - Features state-of-the-art preparation, production, processing, and implementation techniques of nanoscale tailoring of multi-functional cementitious composites starting from laboratory to large scale

Gürkan Yıldırım is currently working as a full-time Associate Professor of Materials Science and Construction Materials in the Department of Civil Engineering of Hacettepe University, Turkey and is affiliated with the Advanced Building Materials Laboratory of the same department. Prof. Yıldırım’s research area of expertise encompasses a wide range of concrete technology, in particular, very ductile fiber-reinforced concretes known as strain-hardening cementitious composites (SHCCs) or engineered cementitious composites (ECCs). His work has mainly focused on the inherent ability of ECCs to recover their own damage (i.e., cracks) without any need of outside assistance through the mechanism known as autogenous self-healing. He has also engaged in studies related to detailed fresh/mechanical/durability property characterization of ECCs, the utilization of nanomaterials in conventional and/or ECC-like composites for performance enhancement and improved self-sensing capability, and ductile composites for repair/maintenance applications. His latest research emphasis is placed on the effective recycling/utilization of construction and demolition (CDW) waste in alkali-activation and development of engineered geopolymer composites (EGC) based on CDW. Prof. Yıldırım is the author/co-author of 2 book chapters and more than 80 journal and conference papers, including 42 journal articles indexed by SCI/SCI-Expanded. He has acted as a reviewer for more than 25 scientific journals and is a Review Editor for the 'Journal of Frontiers in Built Environment – Construction Materials'. He was also involved in several national and international research and governmental projects funded by several authorities (i.e., the Ministry of Environment and Urbanization, TUBITAK, the British Council, and the European Commission). Most recently, he was awarded the prestigious Individual Fellowship of Marie Skłodowska-Curie Actions (MSCA-IF-2019) funded by the European Commission to perform research at the University of Bradford, UK.
