CUPAY, AILEEN JOY C., MARASIGAN, NAOMI D., MOJICA, JUSTINE NICOLE A. Cement from Oyster Shell and Clay. Research Study. Science High School, College of Education. Cavite State University, Indang, Cavite. April 2013. Adviser: Mrs. Momeda Callao.
The study entitled “Cement from Oyster Shell and Clay” was conducted at Cavite State University, Indang, Cavite from July 2011 to January 2013. It aimed to: 1) determine the physical properties of the produced cement; 2) determine the combination of materials that will produce the best quality cement; 3) determine the level of acceptability of the produced cement, and 4) compare the produced cement from oyster shell and clay to the commercial cement.
A total of 30 randomly selected persons who are into cement or construction industry such as masons and plasterers were interviewed. They evaluated the fineness, soundness and consistency of the produced cement. The results from the setting time and hardness test were provided to the 30 evaluators for their appraisal and ratings. This was done because of the impossibility of gathering all the 30 evaluators to be present during the test and production. However, pictures of the testing were provided to the evaluators.
The data were gathered through a score sheet given to each of the respondents fromDecember 2012 to January 2013.
Results showed that Tp got the highest rating in fineness among the treatments. Insetting time, T3 had the best rating followed by To, In terms of consistency, Ty obtained the highest rating. For the treatments with oyster shell and clay, T; got the best rating followed by T2 In terms of soundness, To gained the highest rating followed by T,, T and T2 , while in terms of hardness, Tp appeared to be the hardest, followed by T3, then T2 and T.
In general, all the treatments are sufficiently fine, has long setting time, moderately to sufficiently thick, sufficiently sound and acceptably hard.
The observed general pattern was: T3 > T2 > T;. This suggests that the combination of 80 percent oyster shell + 15 percent clay produced the best quality cement among the three experimental treatments. This combination produced cements that have the longest setting time, adequate consistency and hardness that is almost comparable to the commercial cement.
Results of the study showed that even if the quality of cement from oyster shell and clay is not exactly the same with that of commercial cement, it can still be considered as acceptable considering that it is being compared to a ‘gold standard’.
The study validated that it is indeed feasible to produce cement out of oyster shell and clay.
