3. Dry thermal conductivity for crushed rock samples, estimated by using Johansen''s model, showed that an increase of dry density of 15% led to an increase of thermal conductivity of 75%. 4. Latent heat of fusion for all samples shows signiﬁcant dependence on the water content, and less on the density 5.
Density. The density of crushed concrete aggregate is smaller than natural aggregate density. 4. Water Absorption. Water absorption of recycled aggregate is greater than of natural aggregate. It is one of the most significant properties that distinguish recycled aggregate from raw aggregates.

2021-2-12 · What is the density of the aggregate? The relative density (specific gravity) of an aggregate is the ratio of its mass to the mass of an equal volume of water. Key Features: Most aggregates have a relative density between 2.4-2.9 with a corresponding particle (mass) density of 2400-2900 kg/m3 (150-181 lb/ft3). Is the density of sand high or low?
2020-8-31 · This is the main reason due to which the density, specific gravity & absorption of aggregates are important to measure and compensate, in order to maintain the required water to cement ratio during the production of concrete. For example, aggregate having surface moisture on it will increase the water to cement ratio of concrete, whereas dried ...
