WebAug 10, 2024 · Increasing the solar reflectance, or said the albedo, of surfaces of buildings and streets would curtail the convection of heat from these surfaces to the air and thereby … 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.
