It should not be used as a synonym for rock or pebble'.
In the Penguin Dictionary of Civil Engineering, stone is said to be synonymous with coarse aggregate which is defined as that material which stays on a sieve of 5 mm square opening when used in concrete, or on a sieve of 3 mm square opening when used in bituminous material. Aggregates are those stones, i.e. particles of rock which are brought together in a bound or unbound condition to form part of the whole of an engineering building structure. In civil engineering, normal use for aggregates is in concrete or roadstone (Smith & Collis 1993). In this Book, ‘stone$#x2019; is rock which is used, other than as concrete or roadstone aggregate is
