Placing concrete in cold weather often involves heating some of the concrete ingredients, protecting the freshly-placed concrete from freezing, and closely monitoring the strength gain of the concrete.

Curing concrete in cold weather requires knowledge, material and some of these tips. Snow, humidity, and water will prevent your concrete to settle down. Curing concrete in cold weather requires knowledge, material and some of these tips.

The exposure of concrete to cold weather will extend the time required for it to reach initial set, which may require finishing crews to be available for a longer period. Depending on the actual ambient temperature, protection of a concrete placement may require the use of windbreaks, enclosures, or supplementary heat.

Baby, it’s gettin’ cold outside—again. Are you ready to place concrete so cold weather doesn’t damage it and so it can cure in a reasonable amount of time?

Concrete installation in cold weather can be successful if your contractor follows a few guidelines. Do no pour concrete on frozen ground. Mix concrete with hot water, preheated sand and gravel and add extra cement.

How to Plan for a Cold Weather Concrete Pour

ACI 306.1-90, “Standard Specification for Cold Weather Concreting,” is a good starting point for preparing the plan. Section 1.5.1 of this document states the following: “If required, submit detailed procedures for the production, transportation, placement, protection, curing, and temperature monitoring of concrete during cold weather.

Cold weather concreting requires contractors to maintain minimal concrete temperatures to ensure proper strength gain and cure.

Cold weather affects concrete in many ways. Hydration in concrete, the process of gaining strength, is a chemical reaction. When concrete is placed at cold temperatures, hydration can be slowed – and even stopped – which impacts finishing and curing times.

With fall upon us and winter quickly approaching, now is an ideal time to review plant procedures for manufacturing precast products in cold weather.

ACI 306 “Cold Weather Concreting” defines cold weather concreting as a period when for more than three (3) consecutive days, the following conditions exist: The average daily air temperature is less than 5°C (40°F) and, The air temperature is not greater than 10°C (50°F) for more than one-half of any 24 hour period. ete placed during …

Because concrete gains strength more slowly in colder temperatures, temperature needs to be monitored, and certain precautions and measures need to be taken.

Several practices must be addressed in order to produce quality products that meet specifications. By Evan Gurley. For most precast producers, it is that time of the year when cold weather plays an immense role in the procedures, requirements and practices that encompass precast concrete production.
