Effect of Geopolymer on the Unconfined Compressive Strength Value of Clay Soil

:- Weak soils are encountered in many regions, which lack adequate stiffness and strength to resist the loading due to construction project. Soil improvement is a technique for amendment of these geo-materials. Two common method of soil improvement of soil mechanical and chemical stabilization .commonly mechanical procedures include the compaction and earth reinforcement. In the recent years treatment with geopolymer as a chemical stabilization technique has been widely investigate to earth improvement. Many experimental studies were conduct on the behaviour of soil stabilized with the geopolymer. Their results indicate that employing geopolymer improved the resistant behaviours of stabilized soils. solution (M) used were 4 molar, 8 molar, 10 molar, 12 molar and 14.5 molar. Ratios of alkali solution to binder were varied from 0.45 to 0.85 for geopolymer synthesis. Samples were compacted at a consistency of plastic limit with a tempting rod to remove air voids.
