What is a segregation of concrete?
Segregation in concrete is a case of particle segregation in concrete applications, in which particulate solids tend to segregate by virtue of differences in the size, density, shape and other properties of particles of which they are composed. Bleeding (conc.) The term given to the process by which water rises to the surface giving a puddling effect on top of the laid concrete. This is caused by excessive water in the mix, particularly prominent in cold weather.
Definition segregation and bleeding concrete mixture?
The separation of constituents in a heterogeneous mixture creating a non-uniform distribution of concrete mixture.
Define vibration of concrete and its importance?
Vibration is a process by which fully compacted concrete is achived.Importance:Prevents honeycombingPrevents segregation and bleeding of concreteExpuls air from concrete.
What is maximum allowable distance for concrete to free fall?
The maximum allowable distance for concrete to free fall without segregation is typically around 5 feet. Exceeding this height can cause the aggregates and cement to separate, leading to poor concrete quality. It is important to use chutes or other means to control the pour and prevent segregation.

How does Silpozz impact workability in concrete?
Silpozz improves workability by reducing segregation and bleeding, resulting in a more cohesive and easy-to-handle mix.
What is the purpose of a plasticiser of a concrete?
A plasticiser is used in concrete to improve its workability and fluidity without adding excess water. By reducing the surface tension of the mix, it allows for easier placement and compaction, which can enhance the overall strength and durability of the finished product. Additionally, plasticisers can help reduce the risk of segregation and bleeding in the concrete.
Why is there a minimum and maximum tolerance for concrete slump?
Minimum and maximum tolerances for concrete slump are established to ensure the concrete mix achieves the desired workability and strength. A minimum slump ensures that the concrete is fluid enough for proper placement and compaction, while a maximum slump prevents excessive water content, which can lead to segregation and reduced strength. Adhering to these tolerances helps maintain structural integrity and durability of the concrete in its final application.
Define de jure segregation?
Segregation that is imposed by a law !!!!!!!!!!!!!
What are four challenges African Americans face during reconstruction?
Segregation, segregation, segregation, and segregation
Do you vibrate lean concrete?
Yes, lean concrete can be vibrated to ensure proper compaction and eliminate air pockets. Vibrating helps achieve a denser and more uniform mix, which enhances the strength and durability of the concrete. However, care must be taken not to over-vibrate, as this can lead to segregation of the materials. It's essential to follow proper guidelines for vibration techniques and duration.
