Asphalt Cement - an overview | ScienceDirect Topics

Sand seal is an application of asphalt cement covered by a fine (sand) aggregate. Its purpose is to seal the surface and provide enrichment of oxidized asphalt surfaces that become dry and brittle with age. It prevents pavements raveling and provides better surface friction. Usually, rapid setting or medium setting emulsions are used.

CONCRETE MATERIALS AND TESTING

Coke is partially oxidized to carbon monoxide, which reduces the ores to iron. The other product that floats over the molten iron due to its relative lightness is called slag. Slag is composed of calcium oxide (CaO), silica (SiO2) and alumina (Al203). Slag is pulverized into a fine powder called ground granulated blast furnace slag
