FAQs
What concrete grade is used for residential construction in Kolkata?
M20 grade concrete (20 N/mm²) is the standard for most residential slabs and columns in Kolkata. Higher grades (M25, M30) are used for load-bearing elements in multi-storey buildings.
How much does concrete slab work cost in Kolkata?
RCC slab construction in Kolkata typically costs ₹60–₹150 per sq. ft. (including formwork, steel, and concrete). Ready-mix concrete delivery adds ₹4,500–₹6,500 per cubic metre.
How long does concrete need to cure in Kolkata?
Concrete should be cured for a minimum of 7 days for standard work and 14–28 days for structural elements. In Kolkata's hot climate, additional curing measures like jute cover and water spray may be needed.
Can I get decorative polished concrete for my interiors?
