Because the length changes associated with thermal expansion are very small, the CTE is usually expressed in microstrains per unit temperature change. The CTE of Portland cement concrete (PCC) ranges from about 8 to 12 microstrains/°C. The range of CTE values for different concretes reflects the variation in CTE of concrete's component materials.

Jul 10, 2017 · For example, an asphalt roof only reflects an estimated 30% of light that hits your home, regardless of if you have dark or light shingles. Conversely, a metal roof is very reflective, which means that a majority of light rays are reflected away from your home, keeping your home and attic at an even temperature year round.

According to the Department of Energy's (DOE) Cooling Your Home Naturally report, dark, dull colors can absorb 70 to 90 percent of the sun's radiant energy, which can then be transferred into the home. Meanwhile, light-colored paint can help reflect the sun's heat away from the home.

Reflective surfaces (climate engineering) - Wikipedia

Reflective surfaces can deliver high solar reflectance (the ability to reflect the visible, infrared and ultraviolet wavelengths of the sun, reducing heat transfer to the surface) and high thermal emittance (the ability to radiate absorbed, or non-reflected, solar energy). Reflective surfaces are a form of geoengineering.. The most well-known type of reflective surface is the "cool roof".
