4. PLASTICIZERS & POLYMERS :-

PREFACE

Plasticizers are additives that soften the materials (usually a plastic or a concrete mix) they are added to. Although the same compounds are often used for both plastics and concretes, the desired effect is slightly different.

Polymer is a term used to describe molecules consisting of structural units and a large number of repeating units connected by covalent chemical bonds. The term is derived from the Greek words: polys meaning many, and meros meaning pars.
