  • The Pumice Store: Lightweight Aggregate for Concrete Canoes

    The Pumice Store: Lightweight Aggregate for Concrete Canoes

    lightweight aggregates need a pozzolan: It''s one of concrete science''s ironic truths: lightweight aggregates are reactive, and if used with ordinary Portland cement without the mitigating effects of a reactive pozzolan, the concrete inevitably develops a nasty ASR problem—a reaction between the high silica content in the aggregate and the alkali in the hydrated cement paste.

    Understanding the Density of Concrete - Aggregate Research

    Lightweight aggregate in concrete mix affects the appearance, performance, and workability of concrete. The lightweight aggregates are usually brown, orange, or dark gray, and because of their porosity they don''t polish well. Compressive strength, elasticity, and tensile strength are also affected by the use of lightweight aggregates. Lightweight concrete that uses Vermiuclite, Styrofoam, and Perlite as .

    STRUCTURE magazine | Is Lightweight Concrete All Wet?

    To reduce the amount of mixing water absorbed by the lightweight aggregate, concrete suppliers pre-saturate the lightweight aggregates to fill the pore spaces prior to mixing. Concrete suppliers frequently use water-reducing admixtures to help reduce the total amount of mix water and, consequently, the amount of water that will potentially leave the slab over time.
