Improvement of soft clayey soil by bio-polymer

الملخص EN

This examination explains the utilization of bio-polymer powder for clayey soilenhancement.

The article concentrates around examining the strength attitude ofthe clayey soils built up with homogenous bio-polymer.

Carboxy methylcellulose was determined as bio-polymer material to build up the normal softclayey soil.

The biopolymer has been added to the soil with two separated rates(0.5 and 3% ) by total weight of soil.

Different tests were carried out to considerthe impact of utilizing this polymer as a balancing out specialist on thegeotechnical properties of soil.

It was estimated that as the bio-polymer contentexpands in the soil, the specific gravity decreases, while the optimum watercontent (OMC) is expanded.

The results showed different effects on Atterberg'slimits; by increasing the liquid limit(L.

L) and plasticity index(P.

I) while theplastic limit decrease.

The tests additionally mirrored a huge improvement in theunconfined compressive strength (UCS) of the treated soils.

With the incrementin biopolymer content, the consolidation index (Compression index Cc andA R T I C L E I N F O recompression index Cr) decrease
