Abstract:
Hundreds of types of materials such as cementitious grouts, polymer-modified mortars and concrete, epoxy mortars and concrete, etc., are presently available to repair deteriorated concrete surfaces and a vast number of new ones are flowing into the market. Very often, important data such as physical and mechanical test data like bond strength, abrasion-erosion resistance, coefficient of thermal expansion, thermal compatibility with base concrete, permeability, modulus of elasticity, drying-shrinkage, etc., provided by the manufacturer, is scarce and users are sometimes surprised by a material's performance, especially when it is employed in severe climatic conditions. Thirty-five mortars, including a standard cement mortar used as reference, an in-house-formulated silica fume mortar, cementitious grouts, polymer-modified cement-based mortars, and epoxy mortars were studied. This paper presents some of their essential characteristics.
