This study presents an evaluation of use of the cement waste as chemicalstabilizers and recycling fiber glass wastes and plastic waste (PET Bottles)as soil reinforcement, for improving the strength and stability of soils.An experimental program was conducted to investigate the effect ofmaterials waste and evaluate the efficiency of their use on clay soil asstabilizers, this was achieved based on a study of the effect of materialswaste on the properties of clay soil such as optimum moisture content(OMC), maximum dry density and shear strength parameters (cohesion(c)and angle of friction (ɸ)). The aim was to determine the optimum content ofeach of these materials waste and consequently, to reduce the pollutionwhich results from accumulation of (plastics waste (PET: PolyethyleneTeraphathalate), fiber glass and cement waste). A series of laboratorycompaction, triaxial and California Bearing Capacity (CBR) tests werecarried out.Various percentages of cement waste (3, 6, 9, 12 and 15%) of dry weight ofsoil was added to clay soil and tested. Also soil was reinforced randomly bydifferent percentage (0.5, 1.5, 3, 6, 9 and 12 %) of dry weight of soil byfiber glass (length 10-30mm) and Plastic (PET) bottles strips waste (lengthand width (5-10mm)). Soil specimens were compacted at maximum drydensity.Results of soil treated by cement waste indicate that addition of cementwaste increased the shear strength (385.38 mPa at age 2hours) and CBR()to a maximum value for up to 9% addition, when the percentage ofaddition of cement waste was equal to or greater than 9% soil became nonplastic. The OMC decreased with an increase of more than 12% of cement~ V ~waste content. The dry density of the soil decreased from 1.56 to 1.48 g/cm3with an increasing of cement waste content. `Results of soil reinforced by fiber glass and PET bottle indicate that anincreasing of fiber glass and plastic bottle content decreased the maximumdry density and increased the OMC. The highest increase in strength value(386.82 mPa) was achieved when the soil was reinforced by 3.0 % of fiberglass content and (386 mPa) when the soil was reinforced by 1.5% ofplastic bottle content and the highest CBR value was achieved at 3.0% offiber glass and PET bottle content respectively.The highest CBR value was 8.3 times the CBR of natural clay soil for soiltreated by cement waste, 3.6 times the CBR of natural clay soil for soilreinforced by fiber glass and 2.1 times the CBR of natural clay soil forreinforced by PET bottle waste.As a result of this study it is recommended to use not more than 9% ofcement waste, 3% fiber glass waste and (1.5% to 3%) PET bottle waste asstabilizers to improve the shear strength and CBR of clayey soil.
