  Consideration of Soil Temperature in the Modeling of .

  Modeling the structural behavior of concrete at early ages is one of the most challenging, yet fundamental, tasks for civil engineers working on mass concrete. To obtain a reasonably accurate model, a number of factors should be taken into account. Considerations should include both external influences as well as the changes occurring in the complex structure itself. The modeling of an early ...

  Driveways That Add Character | Curb Appeal Ideas

  Though concrete is durable and categorizes as a good building material, it doesn''t make a good choice for building driveways. It''s porous, making it possible for water to get stored in cracks etc. It further leads to problems of staining and mold formation, making it visually unappealing as well as dangerous. Replacing concrete with asphalt is a common and an ideal construction practice ...

  My NASA Data

  An urban heat island occurs when a city experiences much warmer temperatures than in nearby rural areas. Cities are full of rocky surfaces – asphalt, brick, and concrete – which increases the amount of energy from solar radiation they absorb. Urban areas often see temperatures rise 6°C (10°F) hotter than the surrounding suburbs and rural areas. These higher temperatures can cause people ...
