When pouring concrete, you need to take a few tips and precautions. These tips include Precautions when pouring in cold weather and water spraying to prevent water from absorbing into the concrete. It is crucial for the smooth finish of your concrete. You also need to avoid over-finishing it because it will trap water below the surface.
Pouring concrete in cold weather
Pouring concrete in cold weather presents several challenges. Using an air and concrete temperature chart, you must plan your pour. You will also need to plan protection from the cold. Fortunately, technological advances have made concreting adelaide in cold weather possible. Below are some tips to help you succeed with your cold weather pouring project. You can also consult local resources for more information.
First, be aware that concrete can become brittle in cold weather. It may not harden properly, leaving unseen flaws and making your construction susceptible to shifting and cracking. It would be best to take precautions to prevent this by laying heated mats on the ground and using a special concrete blanket to keep the curing mixture warm.
Second, prepare the concrete ingredients ahead of time. You can either buy ready-mix concrete or prepare it yourself. Make sure to warm the aggregate before you start the pour. A ready-mix concrete company will usually prepare it at 65 degrees Fahrenheit, but you must warm the concrete before you start. You may also want to consider accelerating chemical admixtures.
Third, be sure to use suitable materials. The proper materials will make pouring concrete easier. If you need to pour concrete in the cold, consider getting a concrete mix designed for cold weather. You can get free samples of concrete from UNIQUE. You can also talk with a contractor about the proper methods to seal the concrete afterwards.
Pouring concrete in hot weather
Pouring concrete in hot weather can be challenging, but some strategies can make it easier to work in the heat. First, keep concrete and mixing equipment in a cool area and ensure plenty of shade. You can also reduce the water in the mix or add ice to keep the concrete cooler. Also, schedule your pouring sessions when the day is not too hot and ensure that everyone has adequate rest and shade.
The best time to pour concrete is early morning or late evening. It is because it’s cooler these times, and the concrete will hold up better. However, it will be challenging to finish the job if it’s hot out, so start early. You should also avoid pouring in the dark because concrete is more vulnerable to high temperatures.
When pouring concrete, ensure that the concrete is between 50-60 degrees Fahrenheit. It will prevent cracking, but it will also slow down the curing process. Covering the concrete with insulated blankets or straws is a good idea. However, if you can’t wait for 50 degrees to pour, you should invest in a heated enclosure for the project.
Another critical tip when pouring concrete in hot weather is continuously monitoring the temperature. It is vital to ensure that the concrete sets appropriately and is not affected by the weather. While thermometers can be used to measure the concrete after delivery, you should install an embedded temperature monitoring system to continuously measure the concrete’s early age temperature in situ.
Another tip when pouring concrete in hot weather is to keep your concrete mix well-hydrated. Hot weather will cause concrete to shrink and harden, affecting the slabs’ quality. Poorly hydrated concrete is more likely to flake and break under pressure.
One of the most important things to do to prevent concrete from sucking water out of itself is to apply a waterproofing treatment. It will increase the lifespan of the concrete and reduce repair costs. There are several ways to apply waterproofing compounds. These products can be sprayed onto the concrete surface and help the concrete resist the effects of water.
Deicing salts have a high saturation rate and cause frost damage if they penetrate the concrete. It is because deicing salts increase the saturation of aggregates near the exposed surface, where it is more vulnerable to freezing. Furthermore, deicing salts increase the osmotic pressures within the concrete and can cause further damage to frost-susceptible aggregates.
