aggregate and crushed stone coarse and fine aggregate are produced by crushing natural stone. Crushing, screening, and washing may be used to process aggregates from either sand and gravel deposits or stone quarries. Aggregates may be produced from igneous, sedimentary, or metamorphic rocks, but geological type does not by itself make an aggregateemission factors for the crushing, screening, and handling and transfer operations associated with stone crushing can be found in Section 11.19.2, "Crushed Stone Processing." In the absence of other data, the emission factors presented in Section 11.19.2 can be used to estimate emissions from corresponding sand and gravel processing sources.

Strength is an important property to be looked into before selecting stone as a building block. Indian standard code recommends, a minimum crushing strength of 3.5 N/mm 2 for any building block.
