Question

Why should you use a chute for placing concrete instead of dropping it in place?

1) Saves time
2) Saves money
3) Easier to locate and dispense concrete
4) Helps concrete to not separate (without segregation)

Answer 1

Using a chute for placing concrete ensures controlled flow and prevention of material segregation, leading to a consistent and stable mix, thus ensuring structural integrity and leveraging the benefits of lightweight concrete.

Step-by-step explanation:

The question asks why a chute should be used for placing concrete instead of dropping it in place. The main reasons for using a chute are to facilitate the ease of locating and dispensing concrete, and to prevent the segregation of the concrete mix. When concrete is simply dropped, the constituent materials can separate due to the impact, leading to an inconsistent mix with weakened structural properties.

Using a chute helps maintain the mix integrity by allowing for a more controlled flow, ensuring that the concrete remains homogeneous as it is placed. This method is not only more efficient but also enhances the quality of the construction.

Furthermore, by preventing segregation, the chute helps in producing a structure that has the desired durability and resilience, reflecting the inherent advantages of lightweight concrete, which is used for its reduced load, increased longevity, and superior thermal protection.
