Concrete tends to be a heat sink, meaning it does what?

Explanation:
Concrete has high thermal mass, meaning it can absorb a lot of heat without a rapid rise in temperature and then hold onto that energy for a while. As a heat sink, it draws heat from surrounding spaces and stores it in its mass, releasing it slowly later. That slow rate of temperature change is a hallmark of concrete’s behavior as a heat sink, helping to dampen peaks and valleys in indoor temperatures. It isn’t about repelling heat or generating heat; those ideas don’t describe what a heat sink does.
