As Louisiana locals, we understand high temperatures. 🥵 When temperatures rise, concrete construction can become more challenging, but that doesn’t mean your project has to suffer. At Quality Concrete, we understand the unique demands of hot weather concreting and have the expertise to keep your project on track, ensuring both efficiency and quality.
Problems with Hot Weather Pouring
Rapid Moisture Loss – High temperatures and dry winds can lead to rapid evaporation of moisture from the concrete surface, causing shrinkage and cracking. Without proper moisture, the concrete can weaken and lose durability.
Increased Rate of Setting – Hot weather accelerates the setting time of concrete, which can make it harder to properly finish or apply necessary treatments. If the concrete sets too fast, it can lead to poor surface appearance and reduced strength.
Thermal Cracking – Temperature differences between the surface and the core of the concrete can cause thermal cracking. This occurs because the outer layer cools faster, causing stress on the concrete, which may result in cracks.
Reduced Workability – High temperatures can reduce the workability of concrete, making it more difficult to place, consolidate, and finish. This can lead to uneven surfaces and weak spots that may compromise the structure’s longevity.
How We Overcome Hot Weather Challenges
At Quality Concrete, we take a proactive approach to ensure our concrete remains durable and high-performing even in extreme heat. Here’s how we manage the challenges:
Proper Timing and Scheduling – We carefully plan our concrete pours during cooler parts of the day, such as early mornings or late evenings, to minimize exposure to direct sunlight and high temperatures. This allows us to maintain the integrity of the mix and slow down the setting time.
Using Admixtures – By incorporating admixtures like retarders, we can extend the working time of the concrete, allowing for proper placement and finishing even in hot weather. These additives help control the rate of hydration and keep the concrete workable for longer.
Moisture Control – To combat rapid moisture loss, we apply curing compounds or cover the concrete with moist burlap or plastic sheeting. This helps retain moisture, preventing cracks and ensuring the concrete achieves its full strength.
Temperature Control of Materials – We use chilled water or ice in the concrete mix and ensure the aggregates are kept cool. This helps regulate the overall temperature of the mix, reducing the risk of thermal cracking.
Rapid Placement and Finishing – Our team is trained to work efficiently in hot weather conditions, ensuring the concrete is placed and finished quickly while maintaining quality. We also monitor weather conditions closely to make real-time adjustments.
