The use of limestone in the construction industry has been increasing due to benefits as aggregate. Some of these benefits include good strength, low possibility of alkali-silica reaction and the decrease in drying shrinkage in concrete. This research discusses the consumption and general characteristics of the limestone aggregate in USA and Japan.
Aggregates can be used in construction and landscaping to provide adequate drainage, fill voids, protect pipes, and create hard surfaces. Aggregate materials are also useful for water filtration. For example, water will travel through a trench filled with aggregate more quickly than through surrounding soil.
