2021-10-1  1. Introduction. Coarse aggregate, i.e. gravel or crushed rock, is a major constituent of concrete. At the meso-scale, concrete is essentially a composite comprising three phases – mortar matrix, randomly distributed coarse aggregate particles, and interfacial transition zones (ITZ) at the interface between the mortar matrix and coarse aggregate particles.

Environmental Impact of Aggregates - Concrete

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 ...

EFFECTS OF AGGREGATE TYPE, SIZE, AND CONTENT ON

2014-1-8  There has not been much research on the effects of coarse aggregate content on the fracture energy of concrete. One study, conducted by Moavenzadeh and Kuguel (1969), found that fracture energy increases with the increase in coarse aggregate content. Since cracks must travel around the coarse aggregate particles, the area of the
