Comparative Study of Strength Parameters of Clay by Inclusion of Untreated and Treated Coir Fibres

Reinforced soil imparts greater strength to the soil. The reinforcement used is the natural fibre, coir. India is one of the largest leading producers of coir , it can be used as a reinforcement for weak soil such as clay. One of the major limitation is that coir fibre is degradable and hence the durability of coir fiber can be extended by treating it with reagent like sodium hydroxide and dust cleaning reagent. A series of compaction tests were conducted and the optimum moisture content was obtained and from the result unconfined compression test, CBR were conducted and an improvement in the strength parameters was studied.
