Abstract:
The increased use of alternative deicers to rock salt and introduction of anti-icing prior to winter events using concentrated brines has, in some cases, been associated with deterioration of concrete, especially at joints in pavements. While many commercial products are being used, most either are sodium, calcium, or magnesium chlorides, or mixtures of chlorides. In this study, the effects of different concentrations of calcium and magnesium chlorides on concrete are compared to that of sodium chloride. This study, completed in 2009, found that highly concentrated calcium and magnesium chloride brines caused damage to concrete exposed to low-temperature and freezing temperature cycles by formation of expansive oxychlorides. These results were confirmed by subsequent extensive research performed by others. This paper focusses on concrete performance when exposed to the different forms of chlorides.

Traditional placements often require curb and gutter work to be placed, finished, and cured to outline the pavement area before completion of the flatwork. Monolithic placements, or all-in-one placements, improve efficiency by completing the curb and gutter at the same time as the flatwork. Curbing machines with multiple drum options are the proper tools for such placements.

There is a lack of comprehensive guidelines for the use of fiber-reinforced polymer (FRP) dowels in concrete pavement construction. In light of this, NEx: An ACI Center of Excellence for Nonmetallic Building Materials has announced a newly published document SG23.03 (25): NEx Guideline: FRP Dowels in Concrete Pavements.

Increasing use of deicing chemicals can pose a great risk of premature failure of concrete infrastructure such as pavements and bridge decks. This article discusses an immersion study of ordinary portland cement and high-volume fly ash mortars in MgCl2 solution under room temperature and its influence on mechanical properties and transport property.

To support a rapid integration of sustainability principles into paving concrete practice, this study provides a closer look into readily implementable cement and concrete decarbonization strategies. To do so, this study relies on combined stakeholder involvement, quantitative analysis using Life Cycle Assessment (LCA), and the state-of-the-practice in the US paving concrete industry to understand merits of each solution. The results indicate that concrete mix design optimization is a promising, yet not widely applied solution that can reduce costs, enhance durability, and provide average carbon emissions savings of 14 percent. Use of supplementary cementitious materials (SCM) is another solution with multiple benefits, however, the use of SCM is already widely implemented across the USA. Industry-wide improvement in cement carbon footprint due to energy efficiency can provide additional savings of up to 10 percent. Quantifying the environmental footprint of concrete is critical to inform decision-making and enable more sustainable outcomes.
