On an old topic with new research findings that are very “Old School,” dating back to Roman construction materials and the technical composition of the concrete they used and for what types of uses that it is applicable for in current construction techniques. Architecture and Design to this day, uses concrete that has a very unstable performance in comparison and requires continuous maintenance over time. This is especially true when exposed to salt water or just water in general. There is a myriad of mixes available, and all of these mixes contain chemicals that either get leached out over time or lose their chemical properties over time. Then you are left with the basics; sand, lime and aggregate which become decomposed when water is reintroduced by the natural elements that they are exposed to.
“Roman Concrete in Architecture and Design – A Green Product”
If you think “Green” then the Roman mixture of concrete Link is a wonderful product that has a timeless quality to it in many different ways. Concrete is flexible, strong, creative, enduring and can have a very warm organic feel to it that is pleasing to the senses. It is a Green product with a Green footprint. All of this is up to the designer to orchestrate and produce a quality design that is acceptable to the function of the structure as it relates to the project needs. The big drawback is the availability of volcanic ash/pumice and the ability for mixing plants to get and incorporate these materials. In most places around the United States organic volcanic materials and organic ocean products (coral) are hard to get and expensive. Still they are occasionally used in a mix, but this is rare and can work havoc on budgets. Not to mention EPA regulations that also hinder the frequent use of these products in the quantities that would be necessary to make it an every-day design choice.
The Roman Pantheon
History is important and there are lessons to be learned. To visit ancient structures and take in the ambiance of such antiquated places is an amazing experience, and will conjure up many thoughts and questions. Still we must take the lessons learned and proceed forward with innovation and responsible Architectural and Engineering design.
