Pouring concrete at the right temperature guarantees you high-quality outcomes. Regardless of the project you’re undertaking; concrete plays a vital part in the building process. For instance, if you’re installing a new basketball net or workshop in your backyard, you will need concrete to build a solid and durable structure.
However, it’s essential to understand that concrete takes time to dry and harden to offer the desired sturdiness after pouring. On average, concrete takes about 4-8 hours to harden and another 72 hours to cure. For better outcomes, the concrete should be poured at the proper temperatures.
There is an assumption that hot weather reduces the amount of water needed in mixing the concrete and fastens the drying process. However, pouring concrete in hot weather can compromise the shape and quality of the final product. You may end up with a weaker product prone to easy cracking, flaking, and chipping.
Nevertheless, the curing process might take longer than projected if you pour the concrete mixture under too cold weather. The danger of a slow concrete curing process is that it can lead to structural damage to materials or buildings being supported.
Freezing temperatures are also not safe for the concrete as they lead to expansion and possible breaking due to freezing of water in the concrete. Although the concrete breaking might not be experienced immediately, it can form inside the concrete and go unnoticed till a heavy structure is placed causing above it. The weight might lead to the crumbling and collapsing of your building.
What is the Ideal Temperature for Pouring Concrete?
The ideal concrete pouring temperature range between 50-600F. Pouring concrete at 500F temperatures slows down the curing process, while below 400F temperatures might lead to water freezing in the cement. However, temperatures above 600F can lead to faster evaporation of water in the concrete during the curing process, compromising the structural integrity of your concrete. The good news is that you can reduce the effects by watering your concrete frequently after hardening. You can also lightly spray the concrete 5-10 times daily for the first 72 hours to aid the curing process. Note that the concrete should be sprayed after it has hardened, a process that takes about 4-8 hours after pouring.
When to pour concrete?
Although summer seems like the best time for concrete projects, the heat levels could be dangerous. Bearing in mind, the best temperature for pouring concrete is about 50 – 600F. Cool to moderate months of the year are perfect for concrete projects. The months could vary from one region to another; the months could fall in fall, spring or winter if you reside in hot areas.
Just ensure the temperature is within the range given by our experts to get the best results from your concrete project. Make sure at night the temperatures don’t go below 400F to avoid freezing of the concrete that may result in braking or chipping.
Is Time of the Day necessary?
Although the right concrete temperatures are essential for attaining the right finish and consistency in your concrete project, time of the day and weather are vital considerations. The best time to pour your concrete would be before 10 a.m. and after 8 p.m. to avoid the hottest parts of the day. When the temperatures are too high during the summer, consider pouring the concrete mixture at night to give it the best time to cure and harden.
It is advisable to void pouring concrete in the rain since heavy rains may damage the freshly poured concrete. However, after 4-8 hours, when the concrete has hardened, the rainwater can help smoothen the curing process by providing ideal hydration rather than directly watering the concrete.
In summary, working on your DIY home projects is a simple process with a few complex considerations to enhance bonding between the paste and the aggregate. If you do it correctly under the proper temperatures, your concrete will be stronger to last for years. However, it’s essential to research and learn more about mixing, pouring, and curing your concrete for better results. A specialist is still recommended toachieve quaity concrete work.
