Conclusions
For monogranular sands there is not correlation between degree of densificationand water contentIl
The value of was not significantly influenced both by the addition of only
cement and the addition of cement plus fiberThe value of cohesion has increased considerably with the addition of cement,
has also seen a further increase with the addition of fiber
