Function of Natural and Industrial Waste as Soil Reinforcement of a Cohesionless Soil
摘要
The need for soil reinforcement to improve the bearing of the soil is a trending method of ground improvement in geotechniques. The reinforcement material adopted in recent days is predominately geosynthetics. Considering this fact, the idea of reusing waste materials as reinforcement emerged recently. Laboratory experiments were conducted to understand the effect of waste as reinforcement material included in this study. Steel strips, a waste material from the industry and used ice cream strips used after treatment were used as partial replacements. The strips of varying length-to-width (L/B) ratios (3, 4, 5, 8 and 10) with negligible thickness were used. The replacement also varies with varying percentages (1, 2, 3, 4 and 5%) of material replacement. A cohesionless soil was prepared in a CBR mould and loaded at a strain rate of 1.25 mm/min. From, the results it is observed that L/D ratio of 8 shows a maximum bearing value indicating its potential function as a partial replacement. With metal strips as a partial replacement, the bearing value increased to 10.3% and the increase in the bearing of natural material is comparatively less say 3.3%.
