Strength characteristic of soft soil reinforced with coir fibres

Use of natural fibres in civil engineering construction practice is often advantageous as they are cheap, locally available, biodegradable, and friendly.Among the available natural fibres, coir fibre especially coconut coir fibre is produced in large quantities in Malaysia and others country such a...
