The recommended slump for reinforced concrete (RCC) work can vary depending on several factors such as the type of construction, the specific requirements of the project, and the construction practices followed in a particular region. However, a common range for slump values in RCC work is between 50mm and 100mm (2 inches to 4 inches).
Here are some general guidelines for slump values in RCC work:
Foundations and Footings: Slump values between 50mm and 75mm (2 inches to 3 inches)
Columns and Beams: Slump values between 75mm and 100mm (3 inches to 4 inches)
Slabs and Pavements: Slump values between 75mm and 100mm (3 inches to 4 inches)
