Designing a Lightweight Structural Concrete Mix

The problems most frequently encountered in designing a lightweight concrete mix are maintaining workability while minimizing unit water content, and establishing availability of mix water for hydration. High absorption rates and rough texture prohibit the accurate determination of the bulk specific gravity of lightweight aggregates.
