Concrete Problems

Haiti’s infrastructure was severely damaged in the recent earthquake. The job of your team of engineers is to formulate a cost-effective and efficient plan by which one ton (2000 lbs.) of concrete can be made for use in the rebuilding effort.

In order to do this, you must understand what concrete is, how it is made, and what determines its strength. Apply your knowledge to develop your own “recipe” for concrete and find the cost of the materials or “ingredients” you need. Then develop a name and logo for marketing your product.

Your team will prepare a report that includes the following information:

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 • A description of how your brand of concrete will be prepared (mixed and dried) • 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 • Calculations with explanations typed out • The name of your product and the logo used to identify it, with an explanation if needed



A hard copy of your team’s report must be submitted at the beginning of class on Tuesday, March 16, 2010. Here is the that I will be using to grade your work.
