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.

Available in PDF, EPUB and Kindle. Book excerpt: Manufactured sands are produced by crushing rock deposits to produce a fine aggregate which is generally more angular and has a rougher surface texture than naturally weathered sand particles.Manufactured sands can also contain significant quantities of rock dust.As natural sand deposits become depleted near some areas of metropolitan growth, the use of manufactured sands as a replacement fine aggregate in concrete is receiving attention.

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.

Book excerpt: Shotcrete: Materials, Performance and Use is a comprehensive textbook covering the current state-of-the-art shotcrete technology. It provides an overview of the many and various uses of shotcrete. Shotcrete is well suited for construction of curvilinear structures (domes, shells, bobsleigh/luge tracks, etc.) and overhead shotcrete applications (seismic retrofit, repairs, ground support, etc.) that could not be constructed technically and/or economically using conventional formed, cast-in-place concrete construction methods. It contains chapters on history, shotcrete materials and mixture proportioning, performance, shotcrete research, equipment and shotcrete application. It is also comprised of shotcrete case history examples including buildings and structures, infrastructure repair and rehabilitation, ground support and shoring, underground support in tunnels and mines, swimming pools and spas, and, finally, architectural shotcrete. This text should be of interest to design engineers and architects considering the use of the technology, as well as academics. It serves as a useful guide to contractors using shotcrete in one or more of its many and various applications.
