Evaluation of Varying Fibre Glass with Plaster of Paris (POP)

Abstract

Plaster of Paris (POP) was reinforced with Varying particle sizes and percentages of E- type fibre glass. The locally sourced POP processed from gypsum rock was bought from Ibeshe village in Ogun State was used as the matrix while E-type fibre glass was used as reinforcement. The fibre glass was reduced to smaller sizes with the aid of a blender and then sieved through oscillatory sieve shaker to obtain (38, 75, and 150µm) sizes that were used. The composite were developed with varied proportion of the reinforcement (3, 6, 9, 12 and 15 by wt.%) the reinforcement was manually mixed with POP and required quantity of water to form slurry. The obtained slurry was poured into the mold and allowed to cure before removal. The cured samples were sundried for 5 days and latter oven dried. The dried samples were subjected to the following mechanical test (Compressive strength, Hardness and Impact) it was observed that particle size (38µm) and 15 by wt.%  gave the optimum result for three mechanical tests carried out. Based on the result obtained, it can be used where unreinforced POP are the major challenges especially where structural properties are required.
