Now that summer is in full swing, everyone has their list of what they want to get done while we can work outside. For some people’s projects, this may include pouring concrete. Whether you are wanting a new patio for the backyard, or a path through your garden, there are a few things to keep in mind when pouring concrete while it is hot out.
Depending on the weather that the concrete is poured in, higher temperatures affect the strength of the concrete once it hardens. This is due to the fact that the top layer of concrete tends to dryer faster in the heat than the bottom layer, so it is important for you to protect the top layer. Since it is tough to avoid the hot weather during the summer, here are some tips for pouring concrete in the heat.
– Have enough people to help with the pouring and finishing processes. IN the heat the water can evaporate quickly and the concrete will be a little less forgiving.
– Use a large size and amount of coarse aggregates. With larger aggregates, the concrete is less likely to shrink.
– Don’t pour during the hottest parts of the day. If possible, pour the concrete in the morning or late afternoon, not right at noon.
– Have an evaporative retarder ready. If it gets too hot out the water will evaporate out of the concrete rapidly.
– Don’t leave equipment out in the sun. Keep all of the tools you plan on using out of the sun and in the shade, you want to reduce the temperature of the concrete as much as possible.
Pouring concrete in the heat may reduce its overall strength, but if done right, you will be fine.
