Book Description :

This chapter discusses strategies for mitigating CO2 emissions from the concrete chain. Current strategies, which focus on cement production processes such as clinker replacement, kiln efficiency, fuel substitution and CO2 capture, among others, are not effective enough to compensate for the increase in production that is expected to occur in the future. Binder use efficiency is therefore a crucial strategy for decreasing environmental impacts. Exploratory data from literature, real market and lab research indicates that the potential for decreasing emissions from the concrete chain is very high, and will require changes to the formulation and processing of concrete, as well as the production of aggregates, cement and fillers.

Book Description :

Carbonation is a major cause of concrete structure deterioration, leading to expensive maintenance and conservation operations. The eco-efficient construction agenda favors the increase of the use of supplementary cementitious materials (SCMs) to reduce Portland cement's consumption and also the use of recycled aggregates concrete (RAC) in order to reduce the consumption of primary aggregates and to avoid landfill disposal of concrete waste. A wide range of literature has been published in the field of concrete carbonation related to the use of SCMs and/or RCA. Fowever, the different conditions used limit comparison, and in some cases contradictory findings are noted. Besides, since most investigations are based on the use of the phenolphthalein indicator, which provides a poor estimate of the real concrete carbonation depth, there is a high probability that past research could have underestimated the corrosion potential associated with concrete carbonation. This chapter reviews current knowledge on concrete carbonation addressing carbonation depth measurement and the use of SCMs and RAC.

This book is dedicated to “High-Performance Eco-Efficient Concrete” and concrete fatigue behavior, more sustainable construction materials, capable of complying with quality standards and current innovation policies, aimed at saving natural resources and reducing global pollution. The development of self-compacting concretes with electric arc furnace slags is a further achievement. In addition, the technical and economic viability of using coarse recycled aggregates from crushed concrete in shotcrete, enhanced quality and reduced on-site construction time are the basic features of prefabricated bridge elements and systems, biomass bottom ash as aluminosilicate precursor and phosphogypsum were discussed. On the other hand, basalt fiber improving the mechanical properties and durability of reactive powder concrete, alkali-activated slag and high-volume fly ash and the potential of phosphogypsum as secondary raw material in construction industry, the effects of fly ash on the diffusion, bonding, and microproperties of chloride penetration in concrete were studied. Increasing amounts of sustainable concretes are being used as society becomes more aware of the environment. Finally, the circular economy as an economic model of production and consumption that involves reusing, repairing, refurbishing, and recycling materials after their service life are presented in this book.

Book Description :

Yeelimite-containing, Ca4Al3O12(SO4), cements are attracting considerable interest for their inherently low CO2 emissions during fabrication, and also because they offer the possibility of tailored properties and performances in the resulting mortars and concretes. Here, we initially disentangle the nomenclature and compositions of these cements and, chiefly, distinguish between yeelimite-rich calcium sulfoaluminate cements (CSA, Al2O3 content ranging between 30 and 40wt%) and belite-rich yeelimite-intermediate (BCSAF, Al2O3 content ~15wt%) cements, also known as sulfobelite. Belite-active BCSAF cement may become an alternative to Portland cement for large-scale structural applications, although more research is still needed. Clinkering, hydration and durability issues of pastes, mortars and concretes derived from yeelimite-containing cements, and their blended cements, are discussed.

Book Description :

The volume of polymeric wastes such as tyre rubber and polyethylene terephthalate (PET) bottles is increasing at a fast rate. An estimated 1000 million tyres reach the end of their useful lives every year and 5000 million more are expected to be discarded in a regular basis by the year 2030. Only a small part is currently recycled and millions of tyres are just stockpiled, landfilled or buried. As for PET bottles annual consumption is over 300 000 million units. The majority is just landfilled. This chapter reviews research published on the performance of concrete containing tyre rubber and PET wastes. Furthermore it discusses the effect of waste treatments, the size of waste particles and the waste replacement volume on the fresh and hardened properties of concrete.
