Science and Technology of Concrete Admixtures presents admixtures from both a theoretical and practical point-of-view. The authors emphasize key concepts that can be used to better understand the working mechanisms of these products by presenting a concise overview on the fundamental behavior of Portland cement and hydraulic binders as well as their chemical admixtures, also discussing recent effects in concrete in terms of rheology, mechanics, durability, and sustainability, but never forgetting the fundamental role played by the water/binder ratio and proper curing in concrete technology. Part One presents basic knowledge on Portland cement and concrete, while Part Two deals with the chemical and physical background needed to better understand what admixtures are chemically, and through which mechanism they modify the properties of the fresh and hardened concrete. Subsequent sections present discussions on admixtures technology and two particular types of concrete, self-consolidating and ultra-high strength concretes, with final remarks on their future. Combines the knowledge of two leading authors to present both the scientific and technology of admixtures Explains what admixtures are from a chemical point-of-view and illustrates by which mechanisms they modify the properties of fresh and hardened concrete Presents a fundamental, practical, and innovative reference book on the topic Contains three detailed appendices that can be used to learn how to use admixtures more efficiently

Eco-efficient Repair and Rehabilitation of Concrete Infrastructures, Second Edition provides an updated state-of-the-art review on the latest advances in this important research field. The first section is brought fully up-to-date and focuses on deterioration assessment methods. Section two contains brand new chapters on innovative concrete repair and rehabilitation materials including: fly ash-based alkali-activated repair materials for concrete exposed to aggressive environments; repairing concrete structures with alkali-activated metakaolin mortars; concrete with micro encapsulated self-healing materials; concrete repaired with bacteria; concrete structures repaired with engineered cementitious composites; concrete repaired by electrodeposition; the assessment of concrete after repair operations and durability of concrete repair. The final section has also been amended to include six new chapters on design, Life-cycle cost analysis and life-cycle assessment. These chapters include maintenance strategies for concrete structures; a comparison of different repair methods; life cycle assessment of the effects of climate change on bridge deterioration; life-cycle-cost benefits of cathodic protection of concrete structures; life-cycle cost analyses for concrete bridges exposed to chlorides and life-cycle analysis of repair of concrete pavements. The book will be an essential reference resource for materials scientists, civil and structural engineers, architects, structural designers and contractors working in the construction industry. Covers the latest research findings on eco-efficient repair and rehabilitation of concrete infrastructures Provides comprehensive coverage from damage detection and assessment, to repair strategies and structural health monitoring Presents a diverse author base that offers insights on construction practice and employed technologies worldwide Includes an entire section on NDT, innovative repair, and rehabilitation materials, as well as case studies on lifecycle cost analysis and lifecycle assessment

The influence of high calcium fly ash as clinker replacement in blended cements on the resistance of concrete structures to the carbonation is presented. The paper concerns of five blended cements made with different contents of supplementary cementitious materials: high and low calcium fly ash and ground granulated blastfurnance slag and one reference cement – Portland cement. The aim was to study the carbonation depth on several concretes designed with a constant water to binder ratio and with various blended cements. Additionally, the prediction of the maximum carbonation depth was proposed. The evaluation of the microstructure was performed using optical microscopy on thin sections in transmitted light. The best results according to the resistance to carbonation achieved the concretes made with Portland-fly ash cement where 14.3 % of high calcium fly ash was used. CEM II/A-W can be used to prove the fc28 and resistance to carbonation for XC3 class.
