Ultra-high performance concrete : a state of the art report for the bridge community /

Advances in the science of concrete materials have led to the development of a new class of cementitious composites, namely ultra-high performance concrete (UHPC). The mechanical and durability properties of UHPC make it an ideal candidate for use in developing new solutions to pressing concerns about highway infrastructure deterioration, repair, and replacement. Since 2000, when UHPC became commercially available in the United States, a series of research projects has demonstrated the capabilities of the material. Three State transportation departments have deployed UHPC components within their infrastructure, and many more are actively considering the use of UHPC. This book documents the research, development, and deployment of UHPC components and includes information about its materials and production, mechanical properties, structural design and structural testing, durability and durability testing, and actual and potential applications. The book concludes with recommendations for the future direction for UHPC applications in the United States.

Ultra-high performance concrete (UHPC) is an advanced cement-based composite material with compressive strength of over 120 MPa, high toughness, and superior durability. Since its development in the early 1990s, UHPC has attracted great interest worldwide due to its advantages. This book covers material selection and mixture design methods for developing UHPC, as well as the performance of UHPC, including fresh and hardened properties, setting and hardening, dimensional stability, static and dynamic properties, durability, long-term properties, and self-healing properties. A range of potential applications and case studies are presented to illustrate how UHPC meets requirements for lightweight, high-rise, large-span, heavy-load bearing, fast-construction, and highly durable structures in civil and construction engineering. Also introduced is a typical new concrete, seawater sea-sand UHPC, which avoids the use of freshwater and river sand in marine construction. The first book to fully cover the design, performance, and applications of UHPC, this is ideal for concrete technologists, designers, contractors, and researchers.

Discusses the latest results in academia and industry on green composites. Existing machinability problems like low processability and reduction of the ductility are addressed and discussed in relation to use of adhesion promoters, additives or chemical modification of the filler to overcome these problems. Recent industrial efforts to minimize the environmental impact, e.g. biodegradable polymer matrix, renewable sources complete the approach.

This book presents select proceedings of the International Conference on Advances in Civil Engineering (ACE 2020). The book examines the recent advancements in construction management, construction materials, environmental engineering, geotechnical engineering, transportation engineering, water resource engineering, and structural engineering. The topics covered include sustainable construction process and materials, smart infrastructures, green building technology, global environmental change and ecosystem management, theoretical and analytical solutions for foundation engineering, smart transportation systems and policy, GIS applications in water resource management, structural analysis for blast and impact resistance, and soft computing techniques in civil engineering. The book will be useful for researchers and professionals in the field of civil engineering.
