Use of Blast Furnace Slag Aggregate in Concrete

The use of blast furnace slag aggregates in concrete by replacing natural aggregates is a most promising concept because its impact strength is more than the natural aggregate.

This gives a stronger and denser concrete. Rounded aggregates give a more workable mix. Angular aggregates make concrete harder to place, work and compact, but can make concrete stronger. STORAGE Aggregates should be stored where they will stay clean, separated from other materials and dry. If the aggregates are very wet use less water in the mix.

Special Types of Concrete - Portland Cement Association

Aggregates in this group are used in moderate-strength lightweight concrete and some of these materials are also used in structural lightweight concrete. Group III concretes are made by incorporating into a cement paste or cement-sand mortar a uniform cellular structure of air voids that is obtained with preformed foam (ASTM C869), formed-in .

Recycled Concrete Aggregate - an overview | ScienceDirect

Recycled concrete aggregate (RCA) are aggregates obtained by recycling clean concrete waste where content of other building waste must be very low – below few per cent. For instance, British standard BS 8500-2 ( BSI, 2006 ) defines RCA as recycled aggregate with maximum masonry/fines content of 5%, maximum lightweight material/asphalt content .
