pouring a slab in Dec
Posted by leonard on October 2, 2006
I am wondering if I can pour a slab in Dec , about 4 yards. Does temp have a bearing when pouring?

Leonard,
Yes, temperature does have a bearing when pouring concrete, however, concrete is poured all year, especially in the South.
If the temperature drops on the day you pour there are several things that can be done to protect the concrete from freezing and to set up in a timely manner.
Your ready mixed concrete producer can put in an accelerator to speed up the initial set. He can also put in hot water if the plant is equipped with hot water.
After the concrete is poured and finished you can put insulating blankets over it to help hold in the heat. Straw is sometimes used but has to be cleaned up later.
Your concrete finisher and your ready mixed concrete producer can advise you on what measures to take depending on the weather on the day you pour.
More information related to this problem can be found at ACI manual Section 306 – 88 Cold Weather Concreting.
