    • ABSRACT - [ Total Page(s): 1 ]ABSTRACTThis project, Design and production of ceiling board using Plaster of Paris (POP) Gypsum materials. Gypsum is basically the raw material required in the manufacturing Plaster of Paris (POP) which posses an outstanding property  and a good material for producing ceiling board.The materials procured for the project are plaster of Paris, fiber, water and mould. The equipment used for the project are scrapper, measuring tape, mixing bowl, bucket. Firstly, water was poured into the container (mixing bowl) and plaster of Paris sprinkled, two minutes was waited for absorption and then the mo ... Continue Reading

      CHAPTER ONE - [ Total Page(s): 1 ]CHAPTER ONE1.0     INTRODUCTIONThis project deals with the design and production of ceiling board using POP gypsum materials. Plaster of Paris (POP) which is calcium sulphate with half molecule of water of crystallization (CaSO4.1/2H20)  and  hygroscopic characteristic obtained by duly  calcined the material that is Gypsum (CaSO4.2H20). It possess an outstanding property of setting and subsequent hardening when mixed with water (Smith, 1896).Gypsum is basically the raw material require to manufacture Plaster of Paris. This is cleaned and washed for removal of impurities, dried in sunlig ... Continue Reading

         

      CHAPTER TWO - [ Total Page(s): 4 ]CHAPTER TWO2.0    LITERATURE REVIEW    In 1888, Augustine Sackett used plaster of Paris sandwiched between several layer to produce what would eventually become Sackett board, the original gypsum board. The  modern gypsum board known as “Sackett board” a composite material that was made of layer of thin plaster placed between four piles of wool felt paper. Sackett board was patented in 1894. In this regards Augustine Sackett is generally considered to be the grandfather of gypsum board manufacturing industry.    Prior to 1894, gypsum had been used for thousand of years as ...

It is not generally considered as a structural element but a finished surface concealing the underside of the roof above.    Due to the dominance of asbestos as ceiling material in building with its health hazard, effort was made to produce ceiling board from Gypsum materials.    It was deduced from water absorption test carried out on the samples and the result indicated that plaster of paris (POP) ceiling b ...
