Which temperature range is ideal for pouring concrete?

• A. 0°C to 10°C
• B. 10°C to 30°C
• C. 30°C to 40°C
• D. 40°C to 50°C

Answer: (B)

The ideal temperature range for pouring concrete falls between 10°C to 30°C. This range provides optimal conditions for the chemical processes that occur during curing. At temperatures within this range, concrete can achieve better workability, allowing for easier mixing, pouring, and finishing without facing complications that can arise from extreme temperatures. When concrete is poured in temperatures below 10°C, there is a risk of delayed curing and the potential for freezing, which can severely damage the concrete's structure and strength. Conversely, when pouring occurs above 30°C, the rapid evaporation of water can lead to surface cracking and insufficient hydration, undermining the concrete's overall strength and durability. Therefore, maintaining the temperature within the 10°C to 30°C range is crucial for ensuring a successful concrete pour that contributes to the longevity and performance of the finished product.
