EVERYDAY SCIENCE

Detailed explanation-1: -According to the International Journal of Engineering Research and technology, Concrete has a high capacity to store heat and is referred to as a ‘high thermal mass’ material which is one of the major causes of the urban heat island effect.

Detailed explanation-2: -If you’ve ever walked barefoot across a sunbaked parking lot, you know firsthand how concrete soaks up and retains the sun’s heat. When temperatures rise, the countless miles of concrete streets, sidewalks, walls and roofs in cities magnify that effect, creating a phenomenon known as urban heat islands.

Detailed explanation-3: -Structures such as buildings, roads, and other infrastructure absorb and re-emit the sun’s heat more than natural landscapes such as forests and water bodies. Urban areas, where these structures are highly concentrated and greenery is limited, become “islands” of higher temperatures relative to outlying areas.

Detailed explanation-4: -A Rutgers-led study shows permeable concrete pavement can benefit the environment. Special permeable concrete pavement can help reduce the “urban heat island effect” that causes cities to sizzle in the summer, according to a Rutgers-led team of engineers. Their study appears in the Journal of Cleaner Production.

Detailed explanation-5: -In conditions hotter than 77 °F, the water used to hydrate and cure the cement can evaporate, increasing the concrete’s temperature and presenting problems such as weakness, shrinkage and cracking. However, proper precautions help you successfully pour concrete during hot or cold weather.
