NORTHEAST SEASONAL POURING TIPS



This is an excerpt from an article published on The Concrete Network website that includes tips for pouring concrete in the fall season in the northeastern states.(www.concretenework.com)

Climate (September – November): Fall typically experiences the most stable weather conditions of the year for pouring exterior concrete. The humidity is low, and the days are warm with cool nights. Frost and freezing temperatures can start to become a factor later in the season. Scheduling new exterior concrete work can be difficult, since concrete suppliers and installers are typically busy finishing as much work as possible before winter arrives.

Mix Designs: Hydration stabilizers and water reducers are commonly used to extend the working life of the concrete without affecting performance. Due to extensive freeze-thaw conditions, this region is prone to spalling and scaling concrete. Air-entrainment admixtures should be mandatory in all exterior concrete placed in this region.

Placement and Curing Practices: Surface evaporative control agents should be available on all jobs, whether they are used or not. The use of curing compounds and cure-and-seal chemicals is commonplace for most exterior pours. Proper water content and concrete finishing practices are critical for long-term durability.

Special Equipment: Sprayers to apply surface evaporative control agents and curing compounds; curing blankets; plastic sheeting.
