CHAPTER FIVE
5.0 CONCLUSION AND RECOMMENDATION
5.1 CONCLUSION
Generally, ceiling is an overhead interior or exterior surface that covers the upper limit of the room. 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 board has an average 8.4 percent water absorptivity compare to Asbestos 0.5 percent. Therefore plaster of paris (POP) ceiling board absorb water readily incase there is water leakage of the roof.
Also, it was deduced from flexural strength test carried out on the samples and the result obtained shows that plaster of paris (POP) ceiling board has a mean flexural stress of 11.4 N/mm2 and Asbestos has an average flexural stress of about 1.00 N /mm2. To this end, it is proved that plaster of paris (POP) ceiling board posses sufficient strength and it is durable.
5.2 RECOMMENDATION
The following recommendations were made from the project:-
ï¶ The ceiling board posses sufficient strength and it is more durable, therefore it is good for use as ceiling finishing
ï¶ The sheet are sound absorbers, electrical insulator, and therefore can be used as demarcating panels.
ï¶ The ceiling board offers sufficient resistance to fire.
ï¶ It absorbs water more readily in case there is water leakage of the roof.
ï¶ The production of plaster board put little pressure on the environment thus; it is not hazardous to the health.

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 ... 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 gyp ... Continue reading---
