Cement is not nearly as strong as concrete. For that reason, it is used more in residential projects than in industrial projects (Concrete). Industrial projects require more strength. Cement is very common in laying the foundation for housing (Cement). It is not nearly strong enough to lay the foundation for industrial buildings. It can also be used to build the house itself. Many patios are made with cement. It is also popular for making driveways, sidewalks, patching, and parking lot. Cement is more durable than asphalt, and it is also more expensive (Cement). Concrete is a very hard, very compact substance. It is much stronger than cement, though it contains many of the same components. It is essentially made by taking cement and then adding sand, gravel, and water (The Chemistry). Its strength makes it useful for high-stress jobs in industry. It has many different types which can be used for specific purposes. One type of concrete is called structural concrete. It is very strong and heavy. It is commonly used to carry structural loads in industrial buildings or build the foundation for industrial buildings (Maslow 104). Another type is called lightweight structural concrete. This concrete is used for the same projects as structural concrete, but it is made with a lightweight aggregate. An aggregate is a grainy material such as sand, crushed gravel, or air-cooled iron, that masses together when bound by some other chemical (99). It is much lighter and therefore easier to work with. Prestressed concrete is an important type of concrete. It is more strong than regular cement. Reinforced concrete is another pivotal form of concrete. Maslow defines reinforced concrete as: “Concrete containing reinforcement and designed on the assumption that the two materials act together in resisting forces” (108). Basically it is concrete that has metal rods running through it to help resist its working forces. Concrete is extremely important in industry. It is used for higher-stress jobs than cement. It is commonly used in such high-stress jobs as bridges, dams, large industrial buildings, and foundations for industrial buildings (Concrete). Cement would not hold up in these situations. |
