impact of granite and gravel as coarse aggregate on concrete

IMPACT OF COARSE AGGREGATE ON COMPRESSIVE

aggregate and any changes in coarse aggregate type can affect its strength and fracture properties. The paper examined the impact of coarse aggregates on compressive strength of concrete. Slump and compaction factor tests were conducted on the mixture of quartzite and crushed granite course aggregates, and quarry dust (fine aggregate).

Coarse Aggregate Properties

The gravel performed poorly because of the weak bond between the aggregate and the cement paste. The granite aggregate, on the other hand, gave the worst results because of its mineral composition. In their granite sample, they found a mineral that is unstable in moist environments which is why the granite specimen's results were poor. Figure 4 ...

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.
