Rome is known as the eternal city....concrete structures made with natural pozzolan such as the coliseum, the pantheon, the aqueducts, etc. have withstood the test of time for over 2000 years. Modern concrete, without pozzolan, often begins to crack and crumble within just a few years. Building and rebuilding comes at a great cost of our resources and our environment. Building concrete structures that are extremely durable, resistant to chemical attack, and very strong makes sense both economically and environmentally.
