This book was released on 2007 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research examined the properties of concrete containing grade 120 slag cement at replacement levels of 0%, 30%, and 50%. The primary concrete properties studied were compressive strength, split-tensile strength, and deicer scaling resistance. Material variations included four sources of ordinary portland cement and two types of coarse aggregate. Strength properties were studied at room temperature and 40°F mix and curing conditions. Deicer scaling resistance was studied for concrete cured under six curing conditions. Carbonation of concrete cured under these six conditions was also investigated.

Download or read book Deicer Scaling Resistance of Concrete Pavements Bridge Decks and Other Structures Containing Slag Cement Phase I written by Scott Michael Schlorholtz and published by . This book was released on 2008 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: The initial phase of this project was conducted to determine whether adding slag cement to concrete mixtures increases the surface scaling caused by the routine application of deicer salt. A total of 28 field sites that included portland cement concrete pavements and bridge decks containing slag cement were evaluated. Laboratory testing was conducted on 6 in. diameter core samples extracted from 12 field sites and 3 subsites, including 6 pavement sites and 6 bridge decks. The laboratory testing program consisted of scaling tests, rapid chloride permeability tests, surface chloride profile tests, and petrographic examination. The results of this study suggest that construction-related issues played a bigger role in the observed scaling performance than did the amount of slag in the concrete mixture. For the scaling tests, only cores extracted from one site exhibited scaling mass loss values that exceeded 1.5 lbs/yd2. It was also noted that the bridge deck cores tended to lose more mass during the scaling tests than the pavement cores. For the rapid chloride permeability tests, the amount of charge passed did not appear to be directly related to the amount of slag in the mixtures. However, the different ages of the concrete at the various sites tended to complicate the interpretation of the test results. For the surface chloride profile tests, the diffusion coefficients estimated for the various samples ranged from about 5.6E-12 m2/s to 1.4E-13 m2/s. Petrographic examinations indicated that four of the seven sites that exhibited scaling showed evidence of retempering. In addition, two of the scaling sites tended to have significantly higher water-cementitious material ratios than was expected from the nominal mixture design information that was provided.

Lawler and published by Transportation Research Board. This book was released on 2007 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: NCHRP Report 566 is designed to help facilitate the use of supplementary cementitious materials to enhance durability of concrete used in highway construction, especially bridge decks. The report includes a methodology for selecting optimum concrete mixture proportions that focuses on durability aspects of concrete and the performance requirements for specific environmental conditions. The methodology is presented in a text format and as a computational tool, in the form of a Visual Basic?driven Microsoft Excel spreadsheet. Background information and a hypothetical case study was published as NCHRP Web-Only Document 110: Supplementary Cementitious Materials to Enhance Durability of Concrete Bridge Decks. The Statistical Experimental Design for Optimizing Concrete (SEDOC), the computational tool for the concrete mixture optimization methodology, and the user?s guide are available in a ZIP format for download.
