Introduction • Aggregates are granular mineral materials used in construction They are used with cementing materials to form man-made “rock” • Typically aggregates are used in portland cement concrete, bituminous (asphalt) concrete, road sub bases and bas • Aggregates are selected for specific uses based on their inherent physical properti.

Civil Concrete Technology Lectures Notes Concrete Definition In its simplest form, concrete is a mixture of paste and aggregates (rocks) The paste, composed essentially of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregat Through a series of chemical reactions called hydration, the paste hardens and gains strength to form the rock-like mass known.
