Research Study. Science High School ( General Science Curriculum), College of Education, Cavite State University, Indang Cavite. May 2017. Adviser: Engr. Roslyn Pena. The study entitled "Asian Green Mussel (Perna Viridis) and Oyster Shells (Crassostrea gigas) as Partial Replacement Of Cement in the Production of Tiles" was conducted from September 2016 to April 2017 at Bancod, Indang, aimed to develop tiles using Asian green mussel and oyster shells as partial replacement for cement. Specifically, it aimed to: determine the best combination of mussel and oyster shells in development of tiles; determine the characteristics of the tiles in terms of strength, texture, and color produced from Asian green mussel and oyster shells; determine the cost of production of the Asian green mussel and oyster shells. The researchers used the following treatments in the conduct of the study; To — 0% oyster shells, 0% mussel shells, 100% cement, 100% sand; Tl — 10% oyster shells, 10% mussel shells, 80% cement, 100% sand; T2— 20% oyster shells, 20% mussel shells, 60% cement, 100% sand; T3 — 30% oyster shells, 30% mussel shells, 40% cement, 1000/0 sand; T4— 40% oyster shells, 40% mussel shells, 20% cement, 100% sand; Ts— 100% oyster shells, 0% mussel shells, 0% cement, 100% sand; T6— 0% oyster shells, 100% mussel shells, 0% cement, 100% sand. The binder used in the conduct of the study was a mixture of powdered oysters shells, powdered mussel shells, and cement. The seashells were powdered manually by means of a hammer or other pounding equipment like lusong where the seashells' particles were made fine. The powdered shells were strained by means of sieve (No.35) to segregate the bigger particles from the finer ones. The powdered Asian green mussel shells and oyster shells together with the port land cement and sand were mixed and were added with water. The prepared mixtures were poured into the assigned molders. The molded tiles were dried under room temperature and were removed from the molders after 24 hours and weighed at the day. The produced tiles were brought to DOST, Taguig City for the bending strength test and was surveyed by 30 participants all throughout including engineers, architects, and construction workers in terms of the color and texture. Treatment 5 and 6 did not produce a hardened tile upon sun drying, only treatments 0 to 4 formed hardened tiles. Based on the sensory evaluation of the produced tiles with 30 respondents, the best combination of Asian green mussel and oyster is treatment 4 with a 40% oyster shells, 40% mussel shells, 20% cement, and 100% sand, gave the highest modulus of rupture of 6.55MPa. This is followed by treatment 3 with a 30% oyster shells, 30% mussel shells, 40% cement, and 100% sand, gave the modulus of rupture of 6.40 MPa. The cost of production is, P 7.85/tile for treatment 1, P7.89/tile for treatment 2, P 7.94 for treatment 3 and P 8.00 for treatments 0 and 4.
