Question

What is a characteristic of pouring concrete at low (cold) temperatures?

1) Concrete gains very little strength at low temperatures
2) Concrete gets harder more rapidly
3) Concrete sets up more quickly
4) Cold weather has no effect on concrete

Answer 1

Pouring concrete at low temperatures can result in concrete gaining very little strength, setting up more quickly, and being affected by cold weather. However, it doesn't get harder more rapidly.

Step-by-step explanation:

Pouring concrete at low (cold) temperatures can have several characteristics. One characteristic is that concrete gains very little strength at low temperatures. This means that the concrete takes longer to harden and reach its full strength. Another characteristic is that cold temperatures can cause the concrete to set up more quickly, as the cold weather can speed up the hydration process. However, it's important to note that concrete doesn't get harder more rapidly with cold temperatures. Lastly, cold weather can have an effect on concrete, as it can slow down the setting and curing process.
