- Water Absorption: This property measures the ability of the fine aggregate to absorb water. Aggregates with higher water absorption tend to hold more water, which can significantly impact the workability of the concrete or mortar mix. High water absorption can lead to a need for additional water in the mix, potentially affecting the strength and durability of the concrete. Conversely, aggregates with low water absorption will release water during mixing, which can improve workability.
Additional Information
-
Fineness Modulus: This is a measure of the coarseness or fineness of the aggregate.
-
Particle Size Distribution: This refers to the distribution of different-sized particles within the aggregate.
-
Specific Gravity: This is the ratio of the density of the aggregate to the density of water, which indicates the heaviness of the material but not its water-retaining properties.
