Book Synopsis Eco-efficient concrete by : F. Pacheco-Torgal
Download or read book Eco-efficient concrete written by F. Pacheco-Torgal and published by Elsevier Inc. Chapters. This book was released on 2013-02-04 with total page 624 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Book Synopsis Eco-efficient concrete by : E. Güneyisi
Download or read book Eco-efficient concrete written by E. Güneyisi and published by Elsevier Inc. Chapters. This book was released on 2013-02-04 with total page 624 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since ordinary self-compacting concrete (SCC) is usually associated with high material costs due to its high binder and chemical admixture content, researchers are currently attempting to produce SCC with high volumes of supplementary cementitious materials (SCMs), to make it cost effective and more durable. The SCMs used in this type of SCC, namely fly ash (FA), ground-granulated blast furnace slag (GGBFS), silica fume (SF), metakaolin (MK) etc., are generally industrial by-products and waste materials. A subsidiary effect of this SCC composition is to conserve the environment and non-renewable natural material resources. This chapter reviews the current literature on fresh properties of SCC containing high-volume SCMs, and explains the effect of high-volume SCMs on the mechanical and durability-related properties of SCC.
Book Synopsis Eco-efficient concrete by : B.L. Damineli
Download or read book Eco-efficient concrete written by B.L. Damineli and published by Elsevier Inc. Chapters. This book was released on 2013-02-04 with total page 624 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Eco-efficient concrete written by F. Pacheco-Torgal and published by Elsevier Inc. Chapters. This book was released on 2013-02-04 with total page 624 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of sealers is a common way of contributing to concrete durability. However, the most common ones are based on organic polymers which have some degree of toxicity. The regulation (EU) 305/2011 related to the construction Products regulation (CPR) emphasizes the need to reduce hazardous substances. Therefore, new low-toxicity forms to increase concrete durability are needed. Recent investigations in the field of biotechnology show the potential of bioinspired materials in the development of low toxic solutions. This chapter reviews current knowledge on the use of bacteria for concrete with enhanced durability. It covers the use of bacteria in concrete admixtures and also biomineralization in concrete surface treatments. Results from practical applications exposed to environmental conditions are still needed in order to confirm the importance of this new approach.
Book Synopsis Eco-efficient concrete by : İ.B. Topçu
Download or read book Eco-efficient concrete written by İ.B. Topçu and published by Elsevier Inc. Chapters. This book was released on 2013-02-04 with total page 624 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ground granulated blast furnace slag (GGBFS) is a by-product of the iron-making process and because of its high calcium silicate content it has excellent cementious content and has been used in the construction industry for years as a replacement for ordinary Portland cement (OPC). GGBFS is also routinely used to limit the temperature rise in large concrete pours and is therefore a desirable material to use in mass concrete placements where control of temperatures is an issue. The more gradual hydration of GGBS cement generates both lower peak and less total overall heat than OPC. GGBFS was approved for use at a 70% replacement even though it is only allowed to use a maximum 25% instead of cement. It has a higher proportion of the strength-enhancing calcium silicate hydrates (CSH) than concrete made with only OPC, and a reduced content of free lime, which does not contribute to concrete strength.

Download or read book Eco-efficient concrete written by M.A.G. Aranda and published by Elsevier Inc. Chapters. This book was released on 2013-02-04 with total page 624 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Eco-efficient concrete written by I. García-Lodeiro and published by Elsevier Inc. Chapters. This book was released on 2013-02-04 with total page 624 pages. Available in PDF, EPUB and Kindle. Book excerpt: Portland cement-based products (primarily concretes) are the world’s most commonly used building materials. Due to its huge production worldwide, the Portland cement industry poses economic, energy and environmental problems (7% of total world-wide co2 emissions). International concern over how to reduce co2 emissions has given rise within the scientific community to a growing interest in the development of materials and technologies able to reduce the impact of Portland cement and make construction a more sustainable industry. One of the possible alternative materials whose study and use has intensified in recent years is so-called alkaline cement, produced by alkali-activating aluminosilicates, whether of natural or industrial (blast furnace slag, fly ash, etc.) origin. Based on the nature of their cementitious components (the CaO–SiO2–Al2O3 system), alkaline cements may be grouped under two main categories: high-calcium and low-calcium cements. The reaction products governing the characteristics of the two types of end product differ. While the main reaction product precipitating in calcium-rich systems is a C-A-S-H type gel, in low calcium systems the reaction product is a N-A-S-H gel. A third type of alkaline cement, blended or hybrid cements, is a combination of the above. In this group, the reaction products comprise complex mixes of C-A-S-H + N-A-S-H gels. This chapter stresses the interest that has arisen around the study of these new cementitious systems.
