WebThe classification of colours in the NCC is based on solar absorptance, which is the inverse of solar reflectance, expressed as a ratio between 0 and 1. A SA value of 0 indicates that a roof absorbs none of the solar energy applied to it while a value of 1 indicates that a roof absorbs 100% of the incoming solar radiation. NCC = National ... WebFor high-quality concrete construction, a lower water-cement ratio of 0.4 is employed. For concrete construction like driveways and sidewalks, a w/c ratio ranging from 0.6 to 0.7 is normally used. The practical range of water-cement ratio ranges from 0.3 to 0.8 that gives stiff and weak concrete respectively.

WebThe benefits of solar reflective paint (also called heat-reflective paint or anti-glare paint) start with the passive quality of the paint to reflect heat. In other words, once applied, the paint works to reflect the solar rays when the sun is out. The paint does not need any additional support or energy to do its work.
