Answer 1

Explanation:

Segregation of concrete is the separation of cement paste and aggregates of concrete from each other during handling and placement. Segregation also occurs due to over-vibration or compaction of concrete, in which cement paste comes to the top and aggregates settles at the bottom.

Answer 2

To prevent ‘segregation the maximum height’ of placing concrete is 150 cm.

Explanation:

• 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.
