In traditional Indian lime mortar preparation, urine is added to improve the properties. In this research instead of urine, urea (fertilizer)is tried to give a sanitarily viable alternative. Urea is added in the various viz. 1%, 2%, 3%, 4%, 5% with Lime mortar 1:3 and also Fly Ash Lime Gypsum (FAL-G) paste. The resultant composites were cast into cubes of 50 sq.cm area and tested for weight density, water absorption and compressive strength. Results were compared with plain lime mortar cubes and plain FAL-G cubes. FAL-G shows better properties with 3% urea than lime mortar.
