Improvement of Shear Strength and Durability Using a Mix of RHA and Cement

Abstract

Soil improvement is gaining popularity among the Construction engineering works because of the low land surface to population amount in our country. The present study experiment work performed by using the easy or suitable locally available material Rice Husk Ash as a stabilized of soil along with cement. Rice Husk Ash produced is huge Quantity by rice mill industry generally must be disposed off safely in order to have a effect minimum on the environment surface. Generally RHA used for geotechnical works may proved to a economical or suitable method for the pollution free disposal of Rice Husk Ash. In this thesis work clayey soil used was obtained from Badal Pind near Bathinda and Rice Husk Ash used was brought from KGR Argo Private Limited, Hambran Road, Ludhiana. In this present study the effect of Cement and RHA on the clayey soil. To observed this performance Compaction test, California Bearing ratio test, Permeability test and durability test on soil samples. Compaction test may be results by amount adding RHA the MDD decrease and OWC Increases. Tests are performed on different mix proportions of RHA and Cement amount at their with OWC. Soil was mixed with 0%, 6%, 12% & 18% of RHA along with 0%, 3%, 5% & & 7% Cement. The different parameter were understand which showing significant improvement in strength of stabilizing soil. The maximum CBR value is at 7% cement and 12% RHA. Further RHA amount is increased CBR value decreases. Coefficient of permeability (k) may be test study decrease with increase RHA amount and Permeability (k) values increased with Cement contents. Durability test are also examined with RHA and Cement mix proportion after 7 and 14 days curing period. It showing significant resistance to wetting and drying cycles of durability.
