The increased use of deicing salts is causing rapid deterioration of portland cement concrete bridge decks. Soluble chlorides cause corrosion of the steel reinforcing rods with a corresponding increase in volume of the rods. This expansion causes stresses in the concrete which result in delaminations and surface spalling. The repair of surface spalls with portland cement concrete can only be made if traffic can be avoided for several days. A patching material which would allow traffic to resume over the repaired area in a few hours was needed. Polymer concrete (PC) was developed to repair deteriorated portland cement concrete. Polymer concrete is defined as a composite material in which the aggregate is bound together in a dense matrix with a polymer binder. The aggregate is mixed with a monomer mixture and subsequently cured in place. Polymer concrete combines the premix characteristics of portland cement concrete with high strength, long term durability properties and fast cure times. PC placed at temperatures between 35°F and 95°F attains strengths greater than 5000 psi in 2 hours. The high early strength of PC is suitable for use in the repair of highway structures where traffic conditions allow closing of the area for only a few hours.

The practicality of using polymer concrete to repair deteriorated portland cement concrete bridge decks and pavements has been demonstrated. This manual outlines the procedures for using polymer concrete as a rapid patching material to repair deteriorated concrete. The process technology, materials, equipment, and safety provisions used in manufacturing and placing polymer concrete are discussed. The objective of the report is to inform potential users of the various steps necessary to insure successful field applications of the material.

Polymer concrete is a quick setting, high strength, durable patching material used to repair reinforced portland cement concrete. Cure times of approximately one hour can be obtained from 20 deg F to 130 deg F. The complete patching procedure is discussed including the preparation of the patch, calculation of the amount of materials required, and the mixing and placing of the polymer concrete. Suppliers of the chemicals used are listed. Proper storage, disposal, and safety procedures are also outlined. The cost of polymer concrete is also calculated for the methyl methacrylate (MMA) system used in this study. A materials cost (early 1980) of about 16 dollars per cubic foot or 430 dollars per cubic yard is expected

This practical and comprehensive book enables the engineer to diagnose the cause of a fault, choose the appropriate remedial technique and ensure that the repair work is completed satisfactorily. It will be of value to all those who need to commission, supervise or carry out repairs to concrete structures.

This report discusses the use of impermeable, high strength, quick setting polymer concrete as a patching for deteriorated bridge decks. A complete procedure for bridge deck patching is presented. Both laboratory and field tests of polymer concrete were performed. Experiments include determination of cure time and compressive strength for various monomer mixes. Field patches on several Oklahoma bridge decks were placed with the help of the Oklahoma Department of Transportation. The two commercial patching materials, Dupont's Crylon and Rohm and Haas' Plexicrete were also tested. Formulation of the proper monomer system for a polymer concrete mix with suitable properties for bridge deck patching from 20 deg F to 130 deg F is presented. The cost of polymer concrete is estimated at about 16 dollars per cubic foot of patch volume.

This manual was prepared for the Bureau of Reclamation of the United States Department of the Interior. It discusses the Bureau of Reclamation's methodology for concrete repair, addresses the more common causes of damage to concrete, and identifies the methods and materials most successful in repairing concrete damage. This guide contains the expertise of numerous individuals who have directly assisted the author on many concrete repair projects or freely shared their concrete repair knowledge whenever requested.
