Answer: Option A. Less liable to segregation
The increased cohesiveness of concrete makes it less liable to segregation.
The separation of course materials i.e sand, cement, and aggregates from other masses is called segregation of concrete. The cohesiveness of concrete and segregation of concrete are inversely proportional to each other i.e when the cohesiveness of concrete increases, the segregation of concrete decreases.
The cohesiveness of concrete is either increased by increasing the fineness of cement or by increasing the cement content. Therefore, the increased cohesiveness of concrete makes it less liable to segregation.
