1 - 3 12 WHY STUDY THE CHEMISTRY OF MATERIALS? A standard place setting includes metal cutlery, a polymer napkin, and a ceramic dish Traditionally the three major classes of materials are metals, polymers, and ceramics Examples of these are steel, cloth, and pottery
Construction and demolition waste can be used as recycled aggregate in construction The more thoroughly the waste is treated, the higher the quality of the aggregate However, high-quality aggregate is expensive, and thus, economically unviable in countries where natural aggregate is cheaply obtained
aggregates from discarded tire rubber in sizes 20-10 mm, 10- 475mm and 475 mm down can be partially replaced natural aggregates in cement concrete construction also
Possible Use of Some Waste Materials in Road Construction H istorically, naturally available materials like soil, stone aggregates, sand etc had been used for construction of roads For example, boulders, volcanic tuff and lime were used for the construction of Roman roads (Barth 1990) .
