In this study, the coarse aggregate and cement were substituted with glass aggregate (10%, 15%, 20%, 25%, and 30% by weight of coarse stone aggregate) and 10% metakaolin. The water–cement ratio in such concrete mixtures was set at 0.45, and the compressive strength target was set at 30 MPa after 28 days.
The bulk density of aggregates used in normal-weight concrete is typically in the range of 1200 kg/m 3 to 1750 kg /m 3; ... .0% provided that the clay size material (finer than 2 μm) content is less than 1.0% of the total fine aggregate. For coarse aggregates, CSA A23.1 (2019) allows a maximum 1.0% of a coarse aggregate to be …

Yes, the density and weight of concrete can be influenced by the type and specific gravity of the coarse aggregates used. Heavy or dense aggregates can increase the overall weight of the concrete mixture, while lightweight aggregates can reduce it.
of the pellets [22]. It is identified that concrete's plastic viscosity is most influenced by coarse aggregate's flatness, compressive strength of concrete is most influenced by coarse aggregate's angularity, and concrete flexural strength is most influenced by coarse aggregate's roughness [23].
Coarse aggregate means the aggregate which is retained on 4.75mm sieve when it is sieved through 4.75mm.
