Peat is Geotechnically problematic for any infrastructure as it contains a lot of moisture, low shear strength, and high compressibility. This paper particularly focuses on the improvement of peat in Ziro valley, Arunachal Pradesh using cement and rice husk ash. An environmentally responsible replacement to final disposal using rice husk ash as a soil stabiliser because it is a waste product from the rice industry with pozzolanic qualities. By adjusting the amount of rice husk ash put to the peat soil during all of the usual laboratory procedures as 6, 8, and 12% by weight of soil and cement as 5, 10, 15, 20 and 25%. The strength of peat is greatly enhanced by cement, neutralises the impact of organic matter content, and lessens the impact of acidity. with an increasing amount of cement material, the dry density increases and the optimum water content decreases. With increase in RHA content, MDD decreases but OMC increases. Both unsoaked and soaked CBR test were carried out on peat mixed with cement and RHA. For the test specimen made up of soil, cement, and rice husk ash, it was noticed that the mixture of peat-cement-RHA significantly improved the strength characteristic of parent peat soil. S + 25C and S + 25C + 8RHA can be recommended for treating subgrade.
