Abstract Foamed lightweight soil (FLS) is a cement-based lightweight material valued for its low density and ease of placement. This study investigates the combined effects of water content and spent coffee grounds (SCG) as a partial soil replacement on the engineering properties of FLS. Mixes were prepared with water-cement (w/c) ratios of 0.6 and 0.8 and SCG replacement levels of 0 to 3% by equivalent volume of the dry soil fraction.
