Book Description
Styrene-butadiene (S/B) latex modified concrete overlays are being used to protect new bridge decks from rapid deicer-borne chloride intrusion and also in bridge deck rehabilitation efforts. The purposes of this research were to evaluate several commercially-available S/B latex modifiers for bridge deck overlay concrete; and to develop chemical specifications for the material, a prequalification program to permit evaluation of other S/B latex modifiers which become available, and a certification program to insure the user receives a prequalified product. The chemical and physical properties of the latex emulsions were studied (percent solids, percent butadiene, particle size, surface tension, viscosity, etc.) and the material from each manufacturer was finger printed using infrared spectroscopy. The physical properties of concrete made with each material were also determined (workability, strength-compressive, flexural and bond, freeze-thaw and scaling resistance, and chloride permeability).

Premature Failure of Latex Modified Concrete Bridge Deck Overlays in Ohio
Author: Osama Ahmed Abdulshafi
Publisher:
ISBN:
Category : Bridges
Languages : en
Pages : 286
Book Description
This study is an investigation of the cause(s) of premature failure of latex modified concrete (LMC) bridge deck overlays in Ohio. Data and materials for 93 bridge decks overlaid with LMC were collected from five Ohio Department of Transportation Districts. Additional materials were collected and evaluations were conducted through monitoring the construction of seven LMC bridge deck overlays. Overall documentation and evaluation of the overlays and materials obtained are discussed; this includes field survey activities, construction monitoring and laboratory testing and analysis. Characteristics of the LMC mixtures and materials are evaluated and compared to acceptable standards. General findings were that most of the problems were due to the underlying old deck which was contaminated with chloride ions, previously undetected due to insufficient testing. Other conclusions are presented separately under construction monitoring, field surveys, and laboratory testing and analysis.

Failure, Distress and Repair of Concrete Structures
Author: Norb Delatte
Publisher: Elsevier
ISBN: 1845697030
Category : Technology & Engineering
Languages : en
Pages : 352
Book Description
Understanding and recognising failure mechanisms in concrete is a fundamental pre-requisite to determining the type of repair, or whether a repair is feasible. This title provides a review of concrete deterioration and damage, as well as looking at the problem of defects in concrete. It also discusses condition assessment and repair techniques.Part one discusses failure mechanisms in concrete and covers topics such as causes and mechanisms of deterioration in reinforced concrete, types of damage in concrete structures, types and causes of cracking and condition assessment of concrete structures. Part two reviews the repair of concrete structures with coverage of themes such as standards and guidelines for repairing concrete structures, methods of crack repair, repair materials, bonded concrete overlays, repairing and retrofitting concrete structures with fiber-reinforced polymers, patching deteriorated concrete structures and durability of repaired concrete.With its distinguished editor and international team of contributors, Failure and repair of concrete structures is a standard reference for civil engineers, architects and anyone working in the construction sector, as well as those concerned with ensuring the safety of concrete structures. - Provides a review of concrete deterioration and damage - Discusses condition assessment and repair techniques, standards and guidelines
