The more porous the aggregate, the lower the bulk density. 5. Density of Individual Particles: The bulk density is also influenced by the density of individual particles. For example, aggregates made of lighter materials will have a lower bulk density compared to aggregates made of denser materials. In conclusion, the type of bulk …

First, let's convert 1 ton of 10mm aggregate to m3. It is important to note that the density of aggregate may vary slightly depending on its source and composition. However, for our calculation, we will assume the standard density of 1.65 tonnes/m3. 1 ton of 10mm aggregate = (1 / 1.65) m3 = 0.606 m3
