Ceramic Tiles from Green Mussels

Title: Ceramic Tiles from Green Mussels (Perna viridis)

CHAPTER I:

INTRODUCTION

Background of the Study

Building commercial and residential infrastructures in our country is fast growing. One of the building materials is ceramic tile that is used as floorings in bathrooms, dining area, function halls, etc. Because of this, there is a demand of ceramic tiles and its industry is booming. On the other hand, every year, various solid wastes in our country have been a great problem to our government. One example is the shells of Perna viridis commonly known as tahong found near at the sea. These shells are known fossil that contains ninety seven and a half percent(97.5%) calcium carbonate (CaCO3)1, which is a good source of calcium oxide (CaO) that made these shells rigid and firm. The presence of calcium carbonate (CaCO3) would make it an ideal component for tiles. This information brought the idea to the researchers to use the Perna viridis (tahong) shells as raw material for ceramic tile making. Due to its high concentration of calcium carbonate (CaCO3), the proponents therefore would like to substitute it for the main material in ceramic tile making.

Statement of the Problem

Research Problem

Does powdered Green Mussels (Perna viridis) and Foam Polystyrene substitute commercial tiles?

Sub-Problems:

1. Is there differences between Foam Polystyrene and powdered Green Mussel (Perna viridis) to commercial tiles in terms of:

a. Load capacity

b. Porosity

2. Are there differences among the effects of the ratios of powdered Green Mussels (Perna viridis) and Foam Polystyrene in terms of:

a. Load capacity

b. Porosity

Scope and Limitations of the Study

The focus of the study is on the utilization of Perna viridis (tahong) shells as raw material for ceramic tiles. The process of ceramic tile making including tests on properties such as impact strength and porosity are therefore incorporated in the study.
