Design And Production Of Ceiling Board Using Plaster Of Paris (p.o.p) Gypsum Material

CHAPTER ONE 1.0     INTRODUCTION           This project deals with the design and production of ceiling board using Plaster of Paris [POP] gypsum materials. Plaster of Paris [POP] is a white powdery mixture of gypsum. It has been named such because the first deposit of gypsum was found is Paris.
