| Popis: | This Research work is aimed to evaluate the suitability of slightly alkaline liquid sodium silicate for stabilizationof black cotton soil of India. The study also aimed to investigate the effect of applying liquid sodium silicatewith ordinary Portland cement on engineering properties of treated soil. The Laboratory testing involved duringexperimentation are Atterberg limit test, Proctor test, California Bearing Ratio (CBR) test, Swelling test andUnconfined Compressive Strength (UCS) test. The locally available black cotton soil was treated on variouscombinations of liquid sodium silicate with ordinary Portland cement. The cement was taking 3 % constant andliquid sodium silicate varies 1%, 2%, 3%, 5% and 7% of dry weight of Soil. Samples were cured for 4,7,14 and28 days before testing. It was observed that(1) CBR and UCS values increases and reduced the swelling properties up to 3% combination.(2) Beyond 3% combination it reduces the strength development and increases the swelling properties.(3) Curing enhanced strength development from 4 to 28 days. [8]Findings of the Laboratory investigation imply that good quality materials, dense compaction, longer curing andproper proportion of stabilizer should be applied for Cementious stabilization. Only the liquid sodium silicate isnot a suitable stabilizer but it relatively gives encouraging results with combination of 3% cement by dry weightof soil. The Combination of 3% liquid sodium silicate with 3% cement by dry weight of soil was observed to bethe best combination for stabilization of expansive soil as black cotton soil. |
