Abstract

 

Injection applications with injection material types such as bentonite, rheocem, rheobuild1000, bentonite+rheocem was made and the effect of the injection on soil consolidationsettlement was experimentally studied. A sample of natural soil, whose geotechnicalcharacteristics are known to be weak, was analyzed to determine its basic physicalproperties and the sample was injected with mixtures prepared with natural bentonite,rheocem650 and rheobuild1000. Settlement values of these samples under different loadswere experimentally determined and settlement values of the natural sample were taken asreference values. Settlement values for different loads obtained from the experiments were compared with each other. When reference values for all loads on natural samples are taken as (100%), it was seen that the average settlement value of bentonite injectedsamples was 47.19% higher compared to the settlement values of the natural sample, the average settlement value of rheocem injected samples was 18.51% less compared to thesettlement values of the natural sample and the average settlement value ofbentonite+rheocem injected samples was 36.12% less compared to the settlement values of the natural sample.

 

Key words: Soil improvement, cohesive soils, consolidation settlement.
