Environmental Impact of Aggregates Concrete

Aggregates form the major part of concrete and are derived from many types of rock. Granite and limestone are extracted from quarries, crushed and graded. In many parts of the UK, land-based or marine sand and gravel are available: these require some processing, such as washing and grading, before use in concrete. Washing removes deleterious contaminants such as chlorides from marine

How Concrete is Made Portland Cement Association

Aggregates comprise 60 to 75 percent of the total volume of concrete. The type and size of aggregate used depends on the thickness and purpose of the final concrete product. Relatively thin building sections call for small coarse aggregate, though aggregates up to six inches in diameter have been used in large dams. A continuous gradation of particle sizes is desirable for efficient use of the
