Concrete Design & Production. Concrete is a mixture of two components: aggregates and paste. The paste, comprised of cement and water, binds the aggregates (usually sand and gravel or crushed stone) into a rocklike mass as the paste hardens. A properly proportioned concrete mix possesses acceptable workability of the freshly mixed concrete and ...

· construction. Most of materials used in construction produce low albedo and low emissive surfaces. Low albedo surfaces have low reflectivity, and consequently absorb solar radiation, instead of reflecting it back into space. Low emissive surfaces release this trapped heat energy slowly, thus causing the cooling process to progress at a slow ...
