Mix Designs: Cold-weather concrete mix designs are typically used in these regions, but can be replaced with standard mixes, weather permitting. Concrete can typically be placed at any time of the day, and cold weather protection may be needed at night later in the season. The primary considerations include chemical set accelerators to help the concrete set faster and air-entrainment admixtures to help with freeze-thaw conditions. This is the dry season and conditions are most favorable during this time of year for exterior concrete work. Climate (March - April): Spring brings increasing humidity and temperatures. This may … With cold temperatures, time is a factor, so pumping concrete becomes more common. The primary considerations include blankets for heat retention as well as the possibility of tenting in very cold conditions. Mix Designs: Standard mix designs are the norm. Snowfall can occur at any time during the spring months, with wide temperature swings. Timing is critical for saw-cut joints; cutting too soon spoils the concrete while cutting too late fails to fulfill the purpose. This is actually not true, as the best possible conditions for pouring concrete come in spring when the temperature is consistently in the 50s and the skies are cloudy. Due to exposure of the hardened concrete to freeze-thaw conditions in winter, it is prone to spalling and scaling. Smith Company. 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.

Forms can either be removed after pouring concrete to let dry, or be left in the concrete as permanent edging. The primary considerations include blankets for heat retention as well as the possibility of tenting in very cold conditions. Surface evaporative control agents should be available on all jobs, whether they are used or not. Coastal regions will see temperatures moderate earlier, while the deserts remain very warm. The use of curing compounds and cure-and-seal chemicals is commonplace for most exterior pours. Special Equipment: Pouring exterior concrete in the high plains regions in winter typically requires no additional or special equipment. Adding fly ash and set retarders into mixes is normal as the temperatures start to increase. Beginning with site preparation, any snow, ice or standing water needs to be removed from the work area prior to pouring. You may like my other videos. Hydration stabilizers and water reducers are commonly used to extend the working life of the concrete without affecting performance. You can pour in cold weather, as long as certain precautions are taken. Climate (May - September): Sunny and hot! Cold weather concrete can be classified as a period of more than three days where some specific conditions occur under certain temperatures. Straight concrete mixes can also be used, as they tend to set faster than hybrid mixes. Special Equipment: Plastic sheeting; sprayers to apply curing compounds and surface evaporative control chemicals. Proper planning and communication are keys to a successful winter pour. Air-entrainment admixtures should be mandatory in all exterior concrete placed in this region. Placement and Curing Practices: Because of the low humidity in high-mountain regions, rapid surface hydration is common and can be compounded by the intense sunshine and any wind that may be present. Eliminating fly ash and retarders from mixes is normal as the temperatures start to decrease. In the hottest desert regions, most concrete placements take place before 10 a.m. On many larger projects, concrete is placed at night or during the early morning hours to avoid the extreme sun and heat of the day.

Rain is unpredictable and can occur at any time of the day in the summer. Curing concrete in these regions usually requires the use of solvent-based cure or cure-and-seal chemicals to avoid freezing. The best time to pour concrete is when temperatures are expected to remain above 50 degrees for five to seven days, but plans can go awry with the arrival of an unexpected cold front. Late afternoon thunderstorms are common, so exterior concrete pours should be planned for the morning, with rain protection mandatory after the job is complete. The bigger concern is what the temperature will be over the days following the pour, did you record those. Due to extensive freeze-thaw conditions, this region is prone to spalling and scaling concrete. Most rain occurs along the coast. Air entrainment should be mandatory in all exterior concrete placed in this region. The primary considerations include blankets for heat retention as well as the possibility of tenting in very cold conditions.
