Open in App
Solution
The correct option is C Decreases the strength
Flakey materials have a higher Impact and Crushing Value Index. This clearly means these materials will be weak in both gradual and impact loads. And the concrete made by it will provide low strength.
In other way, flakey materials absorb more water and it also does not provide desired workability. So concrete with flakey materials keeps a high water demand which affects (increases) W/C ratio and gives low strength.
