This book is the result of a Special Issue published in Applied Sciences entitled “Low Binder Concrete and Mortars". The main aim of this work is to highlight practical approaches that facilitate the production of low binder content concrete and mortar with an acceptable level of technical performance (e.g., mechanical and durability) and environmental impacts (e.g., ecotoxicological and global warming). Its contents are organized in the following sections: Developing Zero-Cement Binder; Ecotoxicological and Chemical Characteristics of the Non-conventional Materials Used to Replace Cement and Natural Aggregates; Reduce the Environmental Impacts and Resources Use of Binders; Modify the Characteristics of the Cement-Based Materials; Low Binder Concrete On-Site Application; Sustainable Cement-Based Materials in Road Engineering.

This book provides an updated state-of-the-art review on new developments in alkali-activation. The main binder of concrete, Portland cement, represents almost 80% of the total CO2 emissions of concrete which are about 6 to 7% of the Planet's total CO2 emissions. This is particularly serious in the current context of climate change and it could get even worse because the demand for Portland cement is expected to increase by almost 200% by 2050 from 2010 levels, reaching 6000 million tons/year. Alkali-activated binders represent an alternative to Portland cement having higher durability and a lower CO2 footprint. - Reviews the chemistry, mix design, manufacture and properties of alkali-activated cement-based concrete binders - Considers performance in adverse environmental conditions. - Offers equal emphasis on the science behind the technology and its use in civil engineering.

Mortar and concrete made with portland cement has been a popular construction material in the world for the past 170 years or more. However, cement mortar and concrete have some disadvantages such as delayed hardening, low tensile strength, large drying shrinkage and low chemical resistance. To reduce these disadvantages, polymers have been utilized as an additive.Polymer-modified or polymer cement mortar (PCM) and concrete (PCC) are the materials which are made by partially replacing the cement hydrate binders of conventional cement mortar or concrete, with polymers. This book deals with the principles of polymer modification for cement composites, the process technology, properties and applications of the polymer-modified mortar and concrete, and special polymer-modified systems such as M DF cement, antiwashout underwater concrete, polymer-ferrocement, and artificial I wood.The polymeric admixtures or cement modifiers include latexes or emulsions, redispersible polymer powders, water-soluble polymers, liquid resins and monomers.This book describes the current knowledge and information of polymer-modified mortars and concretes, and discusses or reviews the following items in detail:1. Principles of polymer modification for cement composites.2. Process technology of polymer-modified mortars and concretes.3. Properties of polymer-modified mortars and concretes.4. Applications of polymer-modified mortars and concretes.5. Special polymer-modified systems such as MDF cements, antiwashout underwater concretes, polymer-ferrocements, and artificial woods.

The use of concrete and mortar containing coal fly ash, blast furnace slag, and other dispersed technogenic materials is one of the major areas of potential resource savings and improving the environmental efficiency and sustainability of construction. Improving Concrete and Mortar using Modified Ash and Slag Cements presents the results of a study of high-tech concrete on composite Portland cement and slag Portland cement. It explains the possibility of significantly improving the properties of cements and concrete with the introduction of superplasticizers and hardening activators. Features: Describes how additives can reduce costs and lead to more environmentally sustainable production Explains the possibility of obtaining high-tech concrete with a high content of ash, slag, and clinker kiln dust Presents the possibility of significant reductions of the most energy-intensive component of cements Examines the calculated dependences for predicting the technical properties of concrete saturated with dispersed technogenic products Explains the methods of calculating the composition of concrete with specified properties of low-clinker cements Suitable for civil and structural engineers as well as for specialists working in the field of concrete technology, students of civil engineering, and researchers of new construction technologies, this book allows readers to understand new and sustainable ways to improve the properties of concrete and mortar by utilizing additives.

This study therefore investigated and improved cementitious properties of pozzolan blended with calcium hydroxide, gypsum and cement in order to extend its use from low strength mortars to concrete works which can be used for low to medium rise structural applications. Characterization, strength tests and durability tests were performed on pozzolan mixtures under laboratory conditions and the effects of adding gypsum to pozzolan and calcium hydroxide mixtures on the compressive strength and durability of cured concrete specimens were investigated.
