Concrete: Lightweight Pumice Aggregate and Sand
Lightweight Concrete Aggregate: Lightweight pumice aggregate for craft-type precast concrete projects—including statuary, containers, pavers—where a smaller aggregate size (3/8 to 1/8-inch stones with some fines/sand) is desirable.
Lightweight Pumice Sand: Pumice sand + (includes) tiny 1/8-inch stones. Use in lighweight mortars and as an additive to the craft aggregate when more sand content is desired. Also used for lightweight insulative plasters.
Concrete Canoe: National Concrete Canoe Competition (NCCC) Teams: We field scores of inquiries each NCCC season about sourcing our lightweight pumice aggregate and natural pozzolans. Here’s what you need.
Concrete: Performance-Enhancing Pumice Pozzolan
Densifier325™ Standard Pozz: A highly-effective natural pozzolan for precast concrete products as well as formed-and-cast concrete construction like walls, piers and foundations. Used in shotcretes, cementitious grouts, plasters, mortars. Densifier325™ is a must in regions with reactive aggregates that cause ASR and in locations with high-sulfate soils or in applications subject to sulfate and/or chloride attacks. Also effective in high abrasive and freeze-thaw environments.
UltraPozz: An ultrafine (3 micron) pozzolan for high-performance precast concrete products, especially glass fiber reinforced concrete (GFRC) panels and other architectural accent pieces. Also used in ultrafine cementitious grout formulations.
