They are small pyroclastic fragments, dark colored, with 8.5 to 33 percent of interconnected voids. This high porosity is the cause of low unit weights; dry unit weight ranges between 8 and 12 kN/m3 (50.95–76.43 lb/ft3) and moist unit weight usually varies between 11 and 16 kN/m3 (70.06–101.91 lb/ft3). From a geotechnical perspective, lapilli are essentially coarse granular material with friction angles of 34–37°, cohesion of 137–176 kN/m2 (2.86–3.68 lb/ft2), and unconfined compressive strength, qu, equaling 0.39–0.54 MN/m2 (8.15–11.28 lb/ft2). They are used as coarse aggregate in mass concrete and the compressive strength reaches 25.97 MPa at 28 days, with a characteristic strength of fck = 25 MPa (3,625 lb/in.2). The lack of reactive silica eliminates alkali-silica reactivity problems with Portland cement. Concrete blocks with lapilli are normally used in the Canary Islands. The 250d type provides the best characteristics and even serves for structural bearing walls. It reaches a high block strength index (Bk ≥ 6 N/mm2), and provides effective sound and thermal insulation. This material can also be used as a granular material for highways, although the results from compaction tests (Proctor and CBR) vary widely. This extensive Canarian experience with basaltic lapilli could serve as a useful guide for other volcanic areas of the world.
