3 Reasons To Postpone Concrete Paving Projects In Winters

Concrete paving & flatwork sounds tempting in the winter months, as there is no sun on your back and your concrete’s sump level is as ideal as gelato. Wait – did we say gelato? Oh no!

Winters are only ideal for paving projects if you have the capital to invest in energy-intensive equipment. The equipment helps sustain environmental conditions for curing concrete: namely heat. Winter concrete paving can create structural integrity issues, which will blare their true extent by the time of the spring melt, giving you a crumbly concrete flatwork.

Athens-Atlanta Asphalt has some excellent and experience-backed reasons why you need to get done with your concrete projects now, instead of in the winters!

Water Expands upon Freezing

Concrete is very dependent on water to initiate its sump level, setting, & curing properties. Water is a liquid until you reach 39F and then becomes ice. Ice has the property of expanding in volume. If you prepare concrete in Georgia’s winter, the water in the poured concrete will eventually start to expand within the concrete voids. That can create structural weaknesses in the concrete and lead to crumbling & spalling soon as the spring arrives.

Precautionary Methods are Cost Intensive

You will find many methods promising the perfect concrete flatwork in winters. Some suggest using hot water at 65F to prepare the concrete then pouring. Another way is to use heating or insulation blankets and mobile ventilation systems to help the concrete cure while helping to evaporate the bleed water. A cost-effective version of dealing with bleed water entails the constant vacuuming & sponging of poured concrete surfaces. Still, it won’t mention that the scale of the concrete project might make it next to impossible for the laborious sponging task.

Fly ash or water reducers are often suggested to speed up concrete curing, but understand that the higher the impurities in your concrete, especially if it is precast slabs, the more they will affect the service life of the flatwork.

Winter Concrete Additives are Ineffective

During the winter, calcium chloride, a water-soluble salt, is used as an exothermic accelerator in concrete. When combined at 2% of the entire batch, calcium chloride promotes the hydration-curing process. However, this technique must be used cautiously since it isn’t suitable for use in rebar concrete since the calcium chloride in the concrete will corrode the steel over time. It’s not an anti-freeze solution; instead, it’s a method to speed up concrete setting in cold temperatures by preventing water from freezing too fast within the void content.
