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( **Water is the key ingredient, which when mixed with cement, forms a paste that binds it all together. The water causes the hardening of concrete through a process called hydration. The role of water is important because the water to cement ratio is the most critical factor in the production of "perfect" concrete. Too much water reduces concrete strength, while too little will make the concrete unworkable. Because concrete must be both strong and workable, a careful balance of the cement to water ratio is required when making concrete.)**
