c) 150 cm

d) 200 cm.

Correct Answer – (c) 150 cm (According to IS 456:2000)


Concrete segregation can be defined as the process of separating the cement paste and combine those concretes during placement and handling.

In some cases, the segregation can be occurred due to heavy vibration from where the cement paste will come to the top and the aggregates will settle at the bottom portion.

Whenever the depth of concreting is greater than 1.5 m, it has to be placed via temporary inclined chutes
