A brief introduction with an analysis of the qualities of concrete that will be needed for this purpose, the problems associated with making concrete that impact its usefulness, and the particular problems related to concrete that were brought to light by the earthquake in Haiti //• An equation that shows the materials (reactants) needed to make the concrete and the product(s) formed// //• The amount (by percentage and mass) of each material in your concrete • A cost analysis (in table form) of the materials needed to make your concrete, including (but not limited to) the sources of your materials and the amount of each that must be purchased// //• An inventory of materials that will be left unused when the product is made// //• The name of your product and the logo used to identify it, with an explanation if needed//
 * • A description of how your brand of concrete will be prepared (mixed and dried)**

Proposal for Concrete Project:

__//Recipe #1 - Basic Concrete without Aggregate//__ ****
 * Recipe Ideas w/ sources:

__//2 1/2 quarts Portland cement, white or grey 5 quarts sand, white or grey 1 3/4 - 2 quarts water//__ **

Mix the dry ingredients well. Slowly add water until the concrete is workable. Don't add all of the water at once- you may not need the full amount. Continue to add water until the mixture resembles a thick pancake batter.

Recipe #2 - Basic Concrete with Aggregate

2 quarts Portland cement, white or grey 4 quarts sand, white or grey 3 quarts aggregate- rock, pumice, etc. 1 1/2- 1 3/4 quarts water

Mix the dry ingredients well. Slowly add water until the concrete is workable. Don't add all of the water at once- you may not need the full amount. Continue to add water until the mixture resembles a thick pancake batter.

Recipe #3 - Concrete with Perlite** Perlite is an ultra-light, glassy volcanic rock. Added to a concrete mix in higher percentages, it creates an interesting pock-marked, antiqued look in the finished stone.

2 quarts Portland cement, white or grey 3 quarts sand, white or grey 3 quarts perlite 1 quart water Mix the dry ingredients well. Slowly add water. This mixture doesn't contain as much water as a standard concrete recipe because the finished stone should have a more open, porous texture. Therefore add water until the mix resembles a crumbly cookie dough. Press the mix firmly into the mold. [|Link for recipes]

Normal recipe for concrete: With these cautions in mind, here are the proportions for a standard mix:

2 ¾ parts stone and gravel aggregate 2 ½ parts sand 1 part cement ½ part water [|Standard concrete recipe]

Brand Name Ideas: iConcrete

Logo Ideas: (found by Ross)

Our name comes from Apple's products with "i" in front of it such as iPod and iMac. Since we are a concrete company we used "i" and then concrete to form iConcrete. We chose this picture for our logo because it resembles something being built and it looks strong. The actual logo we use will have an eyeball in the middle for the "i" in iConcrete.
