CONDUCTING POLYMERS By Colin Pratt INTRODUCTION Until about 30 years ago all carbon based polymers were rigidly regarded as insulators. The idea that plastics could be made to conduct electricity would have been considered to be absurd. Indeed‚ plastics have been extensively used by the electronics industry because of this very property. They were utilized as inactive packaging and insulating material. This very narrow perspective is rapidly changing as a new class of polymer known as intrinsically

POLYMER COCNCRETE 1. Introduction Despite being thought of as a modern material‚ concrete has been in use for hundreds of years. The word concrete comes from the Latin concretus‚ which means “mixed together” or compounded. Concrete is an extremely popular structural material due to its low cost and easy fabrication. Concrete is made up of sand or stone‚ known as aggregate‚ combined with cement paste to bind it. Aggregate can be of various sizes. It is broadly categorized as fine (commonly
