Abstract:
This paper demonstrates how a model that includes the chemical reactions in concrete, as well as the tortuosity of the concrete, can be used to predict the effects of cations on the ingress of chloride and changes in the hydroxide levels. Scenarios using low and high C3A cements exposed to NaCl, KCl, CaCl2, and MgCl2 are modeled. The predictions are compared to test data presented several years ago by Professor Hansson. The modeling provides a rapid means that can be used to assess both the salt and cement type on the corrosion susceptibility of embedded steel reinforcement in concrete.

Achieving the designed service life of a repair depends on several factors including the material selection. This month’s Q&A discusses using portland-limestone cement instead of specified portland cement to repair concrete severely damaged by freezing-and-thawing cycles and corrosion due to exposure to deicing salts. The repair is expected to last at least 30 years.

Q. Our interior hard-troweled slabs have scaled (Fig. 1). Did this occur because deicing salts were used to melt snow and ice on the slabs so that construction trades could perform their work during the winter months?

Increasing damage, primarily along the joints, has been observed in concrete pavements and flatwork that are subjected to deicing salts. This phenomenon can be attributed to two primary factors: fluid saturation of the concrete leading to freezing and thawing damage, and a reaction (phase change) occurring between chloride-based deicing salts and the cementitious matrix. Little is known about the second factor. This article discusses the reaction, techniques used for quantifying the damage, and approaches to minimize the damage.

The concrete exposed to freeze-thaw cycles, with or without deicing salts presence, can suffer extensive damage on the cement matrix with a direct impact on the structures durability. The prescriptions to be adopted for preventing this concrete deterioration are described in the European Standard EN 206-1. This standard provides specific exposure classes for Concrete Structures exposed to freeze-thaw cycles (XF) and, for each of them, a series of requirements to ensure the necessary durability. Among these requirements there is the adoption of a minimum volume of entrained air, which avoids the excessive development of internal stresses due to ice formation in the cement matrix. The introduction of air significantly reduces the concrete’s mechanical performance. To take account of this aspect, the mix design must be modified with a higher content of cement to restore the final compressive strength. This aspect becomes more penalizing and not much sustainable for high performance concretes (HPC). The aim of the work is to propose a sustainable use of fly ash in concretes, compatible with the XF exposure classes defined in the European Standard. The solution allows to restrict the cement content to the minimum values required, with technological, economic, and environmental benefits, due to using a by-product from coal combustion power plant.
