Logo Explanation:
Our logo name derives from the cleaning product "OxiClean" which uses a chemical reaction with oxygen to get rid of stains in clothing. Our Concrete mixture is air-entrained, which means it is treated with millions of microscopic air bubbles (oxygen) while in the mixing process. Because our concrete is air-entrained it is water-proof and it can withstand freezing temperatures and floods. Because of the amount of oxygen pumped into our concrete mix we named our company "OxiCrete."

Introduction:
====The recent earthquake that occurred in Haiti has caused the country brutal damages. Many homes were destroyed and we are willing to introduce our brand of concrete to help rebuild Haiti. In order to have strong buildings that will not fall so easily we will focus on making a very strong foundation. For this purpose we will use extra strong cement and concrete. Using concrete on the foundations will make a building strong enough to support more movement in case of another earthquake. Concrete was first made in the year 500BC and the major components in concrete are cement, gravel, sand, water and air. Concrete is a very strong material that is inexpensive, plentiful, and easy to make. It is also recyclable and not too harsh on the environment like other materials. For all of the above reasons, using concrete is a great way to start Haiti up again.====

How it will be prepared:
2 ¾ parts stone and gravel aggregate- 814.8 lbs --- 17 bags for a total of $93.33. 2 ½ parts sand - 666 2/3 lbs --- 12 bags for a total of $65.88 1 part cement - 296.296 lbs --- 7 bags for a total of $54.18 ½ part water - 148.15 lbs --- free Total Price --> $213.39 Total Weight --- 1925.9 pounds [|garcia Costs.doc] ===Why purchased from _company as opposed to others- We purchased our products from Ace Hardware because they have low prices but the quality of the products that they sell are superb. We believed that by buying from them we would not be ripped off and we would get are money's worth. They generally had the losest prices for the products that we needed. ===

===Equations: For the following equations, we did the parts that we needed over the sum of all the parts, which is 6 3/4. Then we set that fraction equal to the x value divided by the pounds that we need for our total. Thus, the equation was part needed/6 3/4 = x/2000. Then, the equation would express how many pounds we need for that part. === Aggregate 2 3/4 parts x __= 814.8 lbs 6 3/4 parts whole 2000 lbs__

sand 2 1/2 parts = x __= 666 2/3 lbs 6 3/4 parts whole 2000 lbs__

cement 1 part = x __= 296.296 lbs 6 3/4 parts whole 2000 lbs__

water 1/2 part = x = 148.15 lbs 6 3/4 parts whole 2000 lbs How to mix OxiCrete: ** NOTE: the conditions and humidity of the environment where the concrete is being mixed should be at cooler temperatures for better results.
 * 1)  Pour the dry cement into our concrete mixer.
 * 2) Add precisely twice as much sand as dry cement.
 * 3) Add four times as much aggregate as cement (Aggregate cannot be more than 3/4-inch in diameter)
 * 4) Add an amount of water equal to 55% of the amount of cement. Mix thoroughly. Concrete should be about as thick as pancake mix.
 * 5) Add the air-entrainment agents: salts of petroleum acids. This creates air bubbles in the mix to make a stronger longer lasting concrete.
 * 6) We place the "slump cone" on a flat surface and fill it with concrete. Ram a small stick through the top of the cone and into the concrete to remove any air bubbles. Carefully lift off the metal cone. Approximately 1/3 of the cone should "slump." If more than 1/3 of the concrete cone sags add more concrete to the mix. If less than 1/3 sags then add small amounts of water to the mix until “slumps” properly.
 * 7) Wet the ground before pouring the concrete. One hour after pouring cover the concrete with burlap or cloth tarps and wet thoroughly. Keep the tarps wet for 14 days. Remove tarps after 2 weeks but continue spraying foundation cement with water for another 14 days. Do not build on the foundation until it has cured for 28 days.
