Concrete frost blankets may be valuable items to have on site if you are pouring concrete in cold weather.

According to a contributor to eHow, pouring concrete when temperatures are low is not always a good idea.

This, the expert said, is because the temperature can affect the strength of the concrete and the amount of time the hydration period can last.

However, the article noted that builders could work round these conditions by changing their ingredient ratios accordingly.

"The precise ratios of aggregate, cement and water affect ultimate concrete strength," the analyst added.

Builders can also ensure their concrete pours are protected at night by investing in equipment such as concrete frost blankets and tents.

These products are designed to withstand harsh conditions such as low temperatures and strong winds, thereby allowing you to safeguard any works in progress.

This could potentially save a building company thousands of pounds, as weather-related damage can significantly set back any project.
