S = steam curing; N = natural curing; 5/8 = 5 mm/8 mm aggregate size; a = length of pure bending zone; b = width of the web; d = effective depth; h = slab height; ls = span of the slab; l = length of the slab; ρs = longitudinal reinforcement ratio. Two specimens were precast in each ID, and subsequent researches are aimed at the average value of the two specimens.
