 * Introduction:**

=
Cement is a fine, soft, powdery-type substance that is made from a mixture of elements that are found in natural materials such as limestone, clay, sand and/or shale. When cement is mixed with water, it binds sand and gravel into a hard, solid mass called concrete. Concrete will be needed for this purpose because it is so strong and perfect for these circumstances. This material is used the most frequently than any other man-made substance in the world. Concrete is easy to make because when mixed with water it becomes hard, which is why it will be the most efficient material to rebuild Haiti.=====


 * How the concrete will be prepared:**

Our concrete formula is based on an intricate blend of strength and lightness. At //Solid as Concrete,// we make sure that our roofs will be sturdy enough to withstand anything, yet light enough to produce a valid shelter to Haitian homes. Our trademark is that we formulate a perfect mixture by combining the characteristics of high strength concrete and lightweight concrete. Here is how our concrete is made:

We start with Silica fume Portland cement and water. We use Silica fume cement because it has been known to increase strength and durability of the concrete, which will be perfect for our roofs in Haiti. In order for our product to be strong, we make sure our water to cement ratio is .30. The cement and water are mixed into a paste, which will insure compressive strength to our concrete. We continue by using clay pellets as an aggregate because they make the cement lightweight. After these steps are complete, we are left with a concrete both strong and light and ready to cover any home.

Explanation: Our logo is on a house because we specialize in roofs and reconstructing them in Haiti. Our roofs will be sturdy and firm, yet lightweight so that they will not crush the small houses in Haiti.
 * Calculations:**

Portland Cement + H2O + Clay Pellets + Sharp Sand = Hardened Concrete + Energy (heat)
 * Equation:**

- Portland Cement - Clay pellets - Sharp Sand - Water - Air - Heat
 * Ingredients:**

** source: http://www.cement.org/basics/concretebasics_concretebasics.asp
 * Percentages :

- The equation can be unstable and crack - The concrete can crumble. - needs the right amount of ingredients. - The buildings in Haiti were not build strong and were easily destroyed.
 * Problems with Concrete and Problems in Haiti**
 * -** There can be too much water or not enough water.
