A Brick is a block, or a single unit of a ceramic material used in masonry construction. Typically bricks are stacked together, or laid as brickwork using various kinds ofmortar to hold the bricks together and make a permanent structure. Bricks are typically produced in common or standard sizes in bulk quantities. They have been regarded as one of the longest lasting and strongest building materials used throughout history. In the general sense, a "brick" is a standard-sized weight-bearing building unit. Bricks are laid in horizontal courses, sometimes dry and sometimes with mortar. When the term is used in this sense, the brick might be made from clay, lime-and-sand, concrete, or shaped stone. In a less clinical and more colloquial sense, bricks are made from dried earth, usually from clay-bearing subsoil. In some cases, such as adobe, the brick is merely dried. More commonly it is fired in a kiln of some sort to form a true ceramic.

A seashell or sea shell, also known simply as a shell, is a hard, protective outer layer created by an animal that lives in the sea. The shell is part of the body of the animal. Empty seashells are often found washed up on beaches by beachcombers. The shells are empty because the animal has died and the soft parts have been eaten by another animal or have rotted out. Apart from mollusk shells, other shells that can be found on beaches are those of barnacles, horseshoe crabs and brachiopods. Marine annelid worms in the family Serpulidae create shells made of calcareous tubes cemented onto other surfaces. The shells of sea urchins are called tests, and the moulted shells of crabs and lobsters are called exuviae. While most seashells are external, some cephalopods have internal shells. Seashells have been used by humans for many different purposes throughout history and pre-history. However, seashells are not the only kind of shells; in various habitats it is possible to find shells from freshwater animals such as freshwater mussels and freshwater snails, and it is also possible to find the shells of land snails.

Abstract
A Brick is a block, or a single unit of a ceramic material used in masonry construction. A seashell is a hard, protective outer layer created by an animal that lives in the sea.A seashell is compost of calcium carbonate. Calcium carbonate is a chemical compound with the formula CaCO3. It is a common substance found in rocks in all parts of the world, and is the main component of shells of marine organisms, snails, coal balls, pearls, and eggshells. Calcium carbonate is the active ingredient in agricultural lime, and is usually the principal cause of hard water. It is commonly used medicinally as a calcium supplement or as an antacid, but excessive consumption can be hazardous.It can make the brick much harder.Sea shelled Bricks is a ecofriendly because it lessen waste.Why?Because after eating the food inside the sea shell we throw it to garbage can.That’s how my Sea shelled Bricks start.

Methodology:
Materials: Sea shell Cement Hammer Molding Comtainer Water To make a brick, the seashell must be be crushed first into powder.Then mixed it with the normal cement mixture to make a brick.The mixture of the cement and powdered seashell will be put to a container to take shape.Wait until it dries.

Difference:
The normal bricks are usually made in cement.The difference of my bricks to the normal bricks is I add another ingredients to it to make it much stronger it is the sea shell.I choose the sea shell because it has a hard, protective outer layer created by an animal that lives in the sea.So it can help the brick to be stronger.
