Abstract
This study investigates the performance of concrete sidewalks placed using hot and cold weather concreting practices. The effect that curing methods, types of deicers, and supplementary cementitious material content have on the scaling resistance of concrete is examined in the laboratory and the field. After one winter, petrographic analysis was conducted on the cores from the sidewalk panels.
The results from field evaluation indicate that the concrete sidewalks placed using hot weather concreting showed better resistance against scaling than those placed using cold weather concreting. The results also suggest that the effect of curing method depends on the concreting procedure type. The results confirm the maximum limits recommended by ACI 201.2R Guide for Durable Concrete, the mix proportions with fly ash less than 25% and slag less than 50% have shown better scaling resistance. Based on the petrographic analysis, a correlation between the properties of concrete determined through petrography and scaling on a sidewalk could not be determined.
