Effect of Adding Nanoclay on the Mechanical Behaviour of Fine-grained Soil Reinforced with Polypropylene Fibers
In this study the performance of clay nano-particles on the soil reinforced with Polypropylene fibers (PP-fiber) has been investigated. Also a series of investigations concerning the effect of random orientation of fibers on the engineering behaviour of soil were conducted. Soil mixtures were modified with varying percentages of nanoclay and Fibers. Unconfined compressive strength (UCS), Compac...
متن کاملIdentification of the Origin and Behaviour of Arsenic in Mine Waste Dumps Using Correlation Analysis: A Case Study Sarcheshmeh Copper Mine
Knowledge of the probable origin and behaviour of arsenic certainly gives valuable insights into the potential for transfer in the environment and of the risks involved in mining sites. Sequential extraction analyses are common experiments often used to study the origin and behaviour of potentially toxic elements. The method, however, presents some deficiencies, including labor-intensive proced...
متن کاملChapter 11: Mine Waste Dump
The Overburden of waste and uneconomic mineralized rock is required to be removed to mine the useful mineral resource in a surface mining operation. In this process a dump is formed by casting the waste material and dumping it in nearby area. The dump so formed is known as mine waste dump. Waste dump may be classified as internal and external dump. External dump is created outside the pit where...
متن کاملAmelioration of Degraded Mine Soil for Reclamation Purposes Using an Industrial Byproduct and an Organic Waste
The South African mining industry has been the backbone of the country’s economy for much of the past century. Mining has, however, often caused the degradation of productive soils. The amendment of these soils is often very expensive and often not sustainable. The University of Pretoria in cooperation with Eskom TSI, has over the past seven years conducted a series of trials. These trials have...
متن کاملAnalysis of Reinforced and Un - reinforced Soil Slopes using Abaqus
Assessing the strength of soil slopes and investigating the means for increasing their safety against failure are crucial in construction projects involving large soil masses. Slope stability analyses have traditionally been performed using a limit state approach. However, any presence of reinforcement or local heterogeneity necessitates the use of numerical techniques such as finite element an...
