Abstract: Peat soil has geotechnical properties such as high water content, high organic matter content, low shear strength, low bearing capacity and high compressibility which makes it as a difficult soil for construction of structures in its natural state. In Manipur, India around 4,24,000 hectares of land area is covered by peat soil, so, improvement mechanism is needed for construction of structures upon it. Industries are very less in Manipur, so commonly used stabilising industry by products like fly ash, lime etc are not economically available. Therefore, locally available admixtures such as stone dust ( S D) and kiln dust (K D) have been selected for stabilization of peat soil. Admixtures are mixed with peat soil in different seven (7) percentages: 0%, 2%, 5%, 8%, 10%, 12%, and 15%, respectively. Again the peat soil is also mixed with both stone dust (S D) and kiln dust (K D) in the ratio of (soil: stone dust: kiln dust); 94:3:3, 92:4:4, 90:5:5, 88:6:6 and 86:7:7. Proctor compaction test

Abstract: This paper presents the effect of kenaf fibres in reinforced concrete beams. In investigating the structural behaviour of the beams, four point bending test was conducted on five beams by considering two distinct parameters (i) shear reinforcement arrangement (ii) the amount of kenaf fibres in the aforementioned beams. The beams consists of Two beams with full shear reinforcement by two amount of kenaf fibres, 10kg/m3 and 20kg/m3,respectively and two other beams with 50% increased shear spacing with two different amount of kenaf fibre 10 kg/m3 and 20 kg/m3 were examined. A control beam is made of 0 kg/m3 kenaf fibre with full shear reinforcement .The experimental results suggests that beams with the inclusion of kenaf fibres demonstrates significant increase on the load carrying capacity, ductility and shear strength. Moreover, it was observed that the mode of failure is altered from shear mode to bending mode. Furthermore, this study opines that kenaf fibres are compatible with RC whi
