This European Standard is the first of five parts to assess the thermal compatibility of repair products and systems, including grouts, mortars and concretes and surface protection systems, used for the repair and protection of concrete structures.
Moves with your concrete: Extremely elastic to move with your concrete through changes due to shifting soils, temperature, moisture, and traffic to create a weatherproof seal that banishes dandelions, anthills, and other unsightly crack dwellers. Cuts down on repeated repairs: Just say no to brittle, cracked concrete repairs.
This standard is the second in a series of five parts to assess the thermal compatibility of repair products and systems, comprising grouts, mortars and concretes and surface protection systems, used for the repair and protection of concrete structures.

Dec 12, 2007 · Due to the availability of a wide variety of repair materials in the industry with a wide range of physical and mechanical properties, it is important to determine the compatibility of a repair material with the substrate concrete.
This study evaluates the compatibility of repair materials for concrete bridge decks. A new compatibility test set-up was designed and tested based on the concrete bridge deck cracking and delamination mechanism theory.
COMPATIBILITY OF CONCRETE REPAIR MATERIALS AND SYSTEMS. With aging of the infrastructure and many concrete structures reaching the end of their design life, maintenance and repair is becoming an increasingly important part of the design and construction industry.
A critical action is to ensure the repair crew has been adequately trained on the materials and processes. A concrete repair craftsman is often as much an artist as a technician. It takes a special skill set, pride in the work and patience to repair concrete structures to new condition.

COMPATIBILITY CONSIDERATIONS FOR DURABLE CONCRETE REPAIRS. Concrete repair and rehabilitation will have an even more vital role in the future than it does now. Major reconstruction of our aging infrastructures can no longer be delayed. Critical to achieving long service life of repaired structures is the correct choice and use of materials.
For instance, unmodified Portland cement mortar or grout, latex modified Portland cement mortar or concrete, quick setting non-shrink mortar, and polymer concrete. The choice of such materials is based on their performance and cost. In addition to repair material compatibility […]
this respect, compatibility between the repair materi-al and the existing concrete is of critical importance. In fact, the level of compatibility will generally de-termine whether a repair project is a success or a failure, andrable.
The main reason for the increased acid resistance of the concrete investigated was the formation of a very dense hardened cement paste and aggregate interface with very low porosities. The use of slag cement increased acid resistance as well as portland cements with silica fume (up to 8 percent by mass of cementitious material) or fly ash.
Executive Summary The discussion of repair material compatibility with the existing concrete substrate has been a topic of discussion between concrete repair experts for many years. Most of the compatibility discussions have been
Repair works quality is depending on a lot of fac-tors dealing with properties of the repair materials, the surface preparation of the substrate, the envi-ronment and the worker's qualification. First of all however, it is important to verify the physico-chemical compatibility of concrete substrate and repair materials.
Freeze-thaw cycles can cause considerable damage to porous materials and thus have an adverse effect on the durability of mortars and porous stone. To assess the behavior and frost resistance of two types of porous limestone, three commercially available repair mortars and four mixtures of laboratory-prepared repair mortars …
Sep 12, 2007 · The chloride contaminated undamaged concrete and the repair concrete have to be compatible in order to achieve a durable system. This laboratory study has investigated 13-year-old reinforced concrete specimens with both substrate concrete with mixed-in chlorides and an initially chloride free repair concrete.

compatibility between repair material and substrate concrete. The compatibility between repair material and substrate concrete exists when the composite section of repair material and substrate concrete withstands all stresses induced by applied load under different environmental conditions without experiencing distress and deterioration over a
rable repair. The topic of durability of concrete repair is too broad to be presented in a single paper. This paper, therefore, will be limited to reviewing one problem aspect of repair: compati bility. This paper is an attempt to characterize compatibility between repair materials and existing concrete and its relative contribution to ...
Permeability Compatibility Between Concrete Repair Material and Concrete Substrate - Scoping Study. 8 . Abstract . The primary objective of this report is to develop a robust research program and to highlight the importance of research related to freeze-thaw durability and repair material compatibility with existing concrete substrates.

existing materials and the repair materials … (Vaysburd et al., 2004) The reliability and durability of a repaired concrete substrate and its remaining service life dependson the behavior of the repair material, which is controlled by the compatibilitybetween the two materials making up the repair system. (Czarnecki, 2004)
One aspect of concrete repair that has plagued concrete repair experts and has not been extensively studied is concrete repair material compatibility with the existing substrate and service environment. It is a very complex issue.
