Geofabrics improve load bearing characteristics of flyash
AbstractThermal power plants in India are producing millions of tons of flyash annually. The material is non-plastic and mainly comprises of the oxides of aluminium, iron, calcium and magnesium. It is a fine grained material and, as such, its use is not feasible as an engineering material. Since it is rarely being used commercially, its storage and disposal have created enormous problems. Experiments are being carried out to improve the load bearing characteristics of flyash with the help of geofabrics. This reinforced flyash will be specially useful for the construction of road and railway embankments particularly where extensive fillings are needed. After a detailed study of different types of woven and non-woven fabrics, Madura Coats (type 3C) was selected for the experimental studies. Different laboratory tests, including California Bearing Ratio and Triaxial tests, were conducted for unreinforced as well as reinforced and treated flyash to compare the behaviour of load bearing characteristics. The results are promising and it will be possible to ascertain an economical procedure for the use of reinforced and treated flyash in different civil engineering works.
