Introduction After the tragedy that happened in Haiti on January 12, 2010, the Contract Concrete Creators decided to do our part and help the best way we could. Using concrete to create strong buildings and fix roads. Our company feels it is important that when creating concrete to be resourceful and efficient, the concrete must be durable, have the ability to retain storm water, and in the end have minimal waste from our product. Our concrete is a mixture of: Cement + Water + Granite + Air = Concrete We are using granite as our aggregate because it is considered to be the hardest rock. That way it makes for a better, firmer concrete. Due to the tragedy we want to make sure that the concrete is secure enough, to be sure if anything happened similar to this event, or an aftershock occurred that it would be durable enough to withstand such occurrences. We used a basic Portland Cement, it is very reliable and firm. We needed to make sure that all buildings would be secure so we carefully picked out each product.

Our concrete will be used in Port-au-Prince for buildings as well as roads. Originally these buildings were made out of clay and poor types of concrete and/or cement. This was not good for keeping the buildings stable and the roads clean. Some of the buildings were orphanages that were completely destroyed. With our concrete mix we are going to change that and make sure that everything remains safe and secure.

The process to make concrete is:
 * 1) Crushing the granite
 * 2) Since the cement was already pre-made for us we just have to wet it
 * 3) Then we mix our granite together with the cement to make it more firm, the cement is really used as a paste to hold everything together
 * 4) Mixing it requires heavy machinery, it can take up to 90 minutes sometimes, and water is constantly added to it

Recipe Ideas w/ sources:

Materials used in concrete with percent
Cement 9% Water 17% Granite 68% Air 6%

__Cost__ 1360 pounds of granite = $2040 180 pounds of cement = $34.52 120 pounds of air = $0 __340 pounds of water = $0__ Overall Cost = $2074.52

For Cement, we can only get 47 lb. bags. 4 bags full. That means we had 188 lbs. 8 lbs. left over. Meaning we only wasted $1.44. This means we made are not wasting as a lot of money. The unit price was $8.63.

For Granite, our total price was $2040; this was our most expensive item. The unit price was $1.50 for 1 lb. We are not wasting any money because it is sold by the lb.

The other price options were: For Cement- $29.59 per unit of 47 lbs. Total is $118.36 Wasted- $4.96 - $8.99 per unit of 47 lbs. Total $35.96. Wasted- $1.52 - Those prices are not too bad, but there are better deals.

For Granite- $48.00 per ton. We only need 1360 lbs. We would be wasting over $25,000. - $25.00 per ton. We only need 1360 lbs. We would be wasting $16,000 - Those prices are outrageous and we found a better deal.
