Book excerpt: In cold climates de-icing salts (NaCl, CaCl 2) are regularly used to prevent the freezing of water on the horizontal surface of concrete structures like roadways and walkways which results in salt scaling, one of the major durability issues of the concrete. In this experimental research, the effect of one-week pre-saturation and three curing methods (standard 14-day moist curing, three-day curing, and the usage of a curing compound) on salt scaling resistance was studied in three concrete types including the plain concrete and concretes made with fly ash and slag at 25% and 35% cement replacement, respectively. Two salt scaling test methods used in this research included ASTM C 672/C 672M and its proposed replacement method (one-week presaturation). One-week pre-saturation was observed to improve the salt scaling resistance of the plain concrete and slag concrete while decreasing the resistance of fly ash concrete. The application of the curing compound resulted in lower salt scaling resistance than the standard 14-day moist curing method in fly ash and slag concretes and higher resistance in the plain concrete. The three-day moist curing method showed higher resistance than the standard 14-day moist curing method in fly ash concrete, lower resistance in slag concrete, and similar resistance in the plain concrete. The concrete made with slag showed the highest salt scaling resistance in accordance with ASTM C 672 and its proposed replacement method followed by the plain concrete followed by the concrete made with fly ash.

Available in PDF, EPUB and Kindle. Book excerpt: Concrete durability in climates where freezing and thawing occurs is a continuing problem. It is particularly acute for highway and bridge structures, where de-icing salts are used to combat the effects of frost, snow and ice. These salts can cause damage to concrete and accelerate corrosion of reinforcements. This book presents the latest internat

Download or read book Geopolymers written by J L Provis and published by Elsevier. This book was released on 2009-06-22 with total page 469 pages. Available in PDF, EPUB and Kindle. Book excerpt: A geopolymer is a solid aluminosilicate material usually formed by alkali hydroxide or alkali silicate activation of a solid precursor such as coal fly ash, calcined clay and/or metallurgical slag. Today the primary application of geopolymer technology is in the development of reduced-CO2 construction materials as an alternative to Portland-based cements. Geopolymers: structure, processing, properties and industrial applications reviews the latest research on and applications of these highly important materials.Part one discusses the synthesis and characterisation of geopolymers with chapters on topics such as fly ash chemistry and inorganic polymer cements, geopolymer precursor design, nanostructure/microstructure of metakaolin and fly ash geopolymers, and geopolymer synthesis kinetics. Part two reviews the manufacture and properties of geopolymers including accelerated ageing of geopolymers, chemical durability, engineering properties of geopolymer concrete, producing fire and heat-resistant geopolymers, utilisation of mining wastes and thermal properties of geopolymers. Part three covers applications of geopolymers with coverage of topics such as commercialisation of geopolymers for construction, as well as applications in waste management.With its distinguished editors and international team of contributors, Geopolymers: structure, processing, properties and industrial applications is a standard reference for scientists and engineers in industry and the academic sector, including practitioners in the cement and concrete industry as well as those involved in waste reduction and disposal.

Download or read book Precision of Tests for Assessment of the Deicer Salt Scaling Resistance of Concrete written by J. Marchand and published by . This book was released on 1996 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some aspects of the variability of Test Method for Scaling Resistance of Concrete Surfaces Exposed to Deicing Chemicals (ASTM C 672) measurements are discussed in this paper. The influence of the operator's subjectivity on the visual rating is studied. The relationship between the visual rating and the cumulated mass of scaled-off particles is also analyzed. From a statistical analysis of several hundred different concrete mixtures, the variability of the test method is estimated for various types of concrete considering only the cumulated mass of scaled-off particles. Using the same statistical analysis, the precision of ASTM C 672 is finally compared to that of the Canadian brine immersion test (Precast Concrete Paving Blocks, CAN/CSA A231.2 M85) designed to assess the deicer salt scaling resistance of precast concrete elements.

Download or read book Decing Salt Scaling Resistance written by TR. Naik and published by . This book was released on 2005 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Laboratory mixtures, pilot mixtures, and field construction mixtures were made to evaluate salt-scaling resistance of concrete incorporating large amounts of either Class C fly ash obtained from several different sources or Class F fly ash. The laboratory mixtures that incorporated Class C fly ash up to a fly ash to cementitious materials ratio (FA/Cm) of 60 % by mass exhibited very slight to moderate scaling. Results from the pilot mixtures indicate that it is possible to produce structural-grade, salt-scaling resistant concrete using up to 56 % Class C fly ash. Specimens of a field mixture containing 50 % Class C fly ash showed moderate to severe scaling, and specimens of a field concrete with 40 % Class F fly ash showed slight to moderate scaling. These field mixtures exhibited satisfactory salt-scaling resistance in actual pavements. Comparisons of strength and scaling results suggest that it would be beneficial to allow sufficient time for high-volume fly ash concrete to develop strength before it is subjected to salt-scaling actions.
