Tips for placing concrete in hot and cold weather, MSDS sheets — it’s all here!

Cold weather concrete curing

You need to take special precautions when placing concrete during cold weather. If you don’t, your concrete might not be as strong or durable. The risk is greatest when temperatures go below five degrees celcius during or within 24 hours of placing.

To prevent cold weather concrete problems,

• Use special winter mixes.
• Do not pour concrete on frozen ground or rebar.
• Cover the ground or forms and use heaters to warm the area up.

Hot weather concrete curing

Hot weather conditions can be just as detrimental to concrete as cold weather. Hot weather make concrete harder to work with, and it can also lead to shrinking and cracking.

To prevent problems resulting from hot weather, use windbreaks, sunshades and wet coverings as needed. We may also use water to keep the placement area damp. There are also special admixtures and surface applications we can use to reduce shrinking and cracking.
