Unwanted sound reflection can create acoustic discomfort and lead to problems of speech comprehensibility. Contemporary building techniques enable highly finished internal walls resulting in sound reflective surfaces. In contrast, sustainable construction materials using natural and vegetal materials, are often more porous and absorptive. Hemp shiv is used as an aggregate and when mixed with li...

Increasing the production of high-performance natural fibres that minimise their impact on environment is a challenge flax (Linum usitatissinum L.) cannot address alone. In traditional territories, hemp (Cannabis sativa can be complementary source high added value if yield long line maximised to levels equivalent one flax.

There are at least 1000 types of plant that bear usable fibers [1]. Natural plant fibres are easily obtained in many tropical parts and are available throughout the world. Today these fibres are considered as environment friendly materials owing to their biodegradability and renewable properties [2]. Natural fibres have applications in fields of textile, paper manufacturing, and bioenergy indus...
