Question

According to IS 456-2000, the slump value (in mm) of the concrete used in ordinary RCC work for beams and slabs, etc.

1. 75 to 150
2. 25 to 50
3. 50 to 100
4. 20 to 30

Answer 1

Correct Answer - Option 3 : 50 to 100

Explanation:

According to IS 456-2000, the slump value (in mm) of the concrete used in ordinary RCC work for beams and slabs, etc. is 50 to 100 mm.

For concrete work, low workable concrete is preferred.

Slump value for concrete roads = (20 – 30) mm

Normal RCC work = (80 – 150) mm

Mass concrete = (20 – 50) mm

Columns and slabs = (40 – 50) mm
