ans-0.12 %.
Concept
According to IS 456:2000, for reinforced concrete (RCC) slabs, the minimum percentage of reinforcement using HYSD (High Yield Strength Deformed) bars in either direction should not be less than 0.15% of the total cross-sectional area of the slab.
This requirement ensures that the slab has sufficient reinforcement to carry the loads and control cracking, while also considering the use of high-strength steel like HYSD bars.
