Available in PDF, EPUB and Kindle. Book excerpt: The effects of construction practices and material properties on the performance of concrete bridge decks are evaluated. Emphasis is placed on comparing bridge decks with silica fume and conventional concrete overlays and determining if the silica fume overlays commonly used on bridges in Kansas are performing at a level that justifies the extra cost and construction precautions. Forty continuous steel girder bridges, 20 with silica fume overlays, 16 with conventional overlays and four with monolithic bridge decks are included in the study.

Available in PDF, EPUB and Kindle. Book excerpt: Chlorides that are used for ice control on the Kansas highways cause serious corrosion of the reinforcing steel in concrete bridges. The Kansas Department of Transportation (KDOT) has tried various methods to prevent chloride from penetrating the concrete on bridge decks. In 1990 two silica fume bridge deck overlays were placed on I-470 in Shawnee County along side of two control bridges. While the silica fume overlays have successfully inhibited the chloride penetration of the concrete, extensive cracking occurred in the silica fume overlays. Most of the cracking occurred in the first five years of the bridge deck life. KDOT has made significant changes in curing methods since 1990 to control the early cracking in the silica fume overlays.

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.

This book was released on 2008-11-01 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this research was to examine the applicability of ternary binder systems containing ordinary portland cement (OPC), class C fly ash (FA) and silica fume (SF) for bridge deck concrete. This was accomplished in two parts, the laboratory part and a field application part. During the laboratory studies, four ternary mixtures, each containing either 20% or 30% FA and either 5% or 7% SF were subjected to four different curing regimes (air drying, 7 days curing compound application and 3 or 7 days wet burlap curing). In general, all four ternary mixtures exhibited very good water and chloride solution transport-controlling properties (resistance to chloride-ion penetration, chloride diffusivity and rate of water absorption). However, it was concluded that in order to ensure adequate strength, good freezing and thawing resistance, satisfactory resistance to salt scaling, and adequate shrinkage cracking resistance the FA content should not exceed 20%, SF content should not exceed 5% (by total mass of binder) and paste content should be kept below 24% by volume of concrete. Further, wet burlap curing for a minimum of 3 days was required to achieve satisfactory performance and to obtain a reliable assessment of in-situ compressive strength (up to 28 days) using maturity method. The second part of this research examined the performance of ternary concrete containing 20% FA and 5% SF in the pilot HPC bridge deck constructed in northern Indiana. Using maturity method developed for the purpose of this study, it was determined that the unexpectedly high RCP values of concrete placed late in the construction season were mostly attributed to low ambient temperature. Additional applications of the developed maturity method were also demonstrated. These include assessment of risk of scaling and reduction in time to corrosion initiation as a function of construction date, as well as estimation of long-term RCP values of concrete subjected to accelerated curing.

This book was released on 2011 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 423: Long-Term Performance of Polymer Concrete for Bridge Decks addresses a number of topics related to thin polymer overlays (TPOs). Those topics include previous research, specifications, and procedures on TPOs; performance of TPOs based on field applications; the primary factors that influence TPO performance; current construction guidelines for TPOs related to surface preparation, mixing and placement, consolidation, finishing, and curing; repair procedures; factors that influence the performance of overlays, including life-cycle cost, benefits and costs, bridge deck condition, service life extension, and performance; and successes and failures of TPOs, including reasons for both.

This book was released on 1993 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study evaluated concretes containing silica fume for use in overlays as a suitable alternative to the widely used latex-modified concrete (LMC). A two-lane, four-span bridge deck was overlaid with concrete containing silica fume at 7 percent or 10 percent by mass of the Portland cement as an additional cementitious material. The results of laboratory tests on field concretes containing silica fume were satisfactory. Silica fume concrete (SFC) bonds well with the base concrete and has very low permeability, high strength, and satisfactory freeze-thaw resistance. In the field, over the 5-year evaluation period, cracking and increases in half-cell potentials and chloride content indicated a tendency to corrosion. However, such increases are also evidenced with LMC overlays. Thus, the results indicate that SFC can be effectively used in thin overlays as an alternative to LMC. SFC, as LMC, is prone to plastic shrinkage; therefore, immediate and proper curing must be provided to avoid the shrinkage cracking that can occur under adverse curing conditions.
