Environmental Impact of AggregatesTraduire cette page

Environmental Impact of Aggregates. 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 ...
