Abstract: Off-spec fly ash-based spherical lightweight aggregate (LWA), designated SPoRA, was manufactured and its engineering properties, including specific gravity, dry rodded unit weight, water absorption, mechanical performance, and pore structure, were evaluated. Using the characterized SPoRA, lightweight concrete (LWC) samples were made and properties of the LWC were assessed and compared with samples made using the traditional LWA. The results indicated that fine and coarse SPoRA had 72 h absorption capacities of 16.4% and 20.9%, respectively, which were higher than that of traditional LWA. SPoRA had a saturated surface dry (SSD) specific gravity higher than traditional LWA, which resulted in higher fresh density for the LWC prepared with SPoRA. Large spherical type pores were found for SPoRA similar to the traditional slate-based LWA. The pore size distribution of SPoRA, characterized using a dynamic vapor sorption analyzer, indicated that more than 97% of the pores had pore diameters greater than 50 nm.
