The Role of Concrete Formwork in Today’s Massive Structures

All the massive structures we have today wouldn’t be possible without the help of concrete formwork. In fact, not only today’s structure but even the ones in the past. Such formwork system can serve as temporary structures like concrete steps, sidewalk, patios or can even be a complex building made of concrete reinforced with a steel structure. Also, the formwork serves as support to the weight of the concrete until it has enough time to dry forming into a specific shape and it there is enough strength to support itself.


The Different Types

Here are some of the most known types of concrete formwork that has greatly contributed to the structures we have today.

  •        Timber Formwork- It is moisture-resistant and if often used for traditional types of structures. It is simple and reusable.
  •        Engineered or Prefab Formwork Mold- typically built with metals that allow them to be reused over and over.
  •        Plastic Formwork Mold- used in mass housing development. This type is easy to assemble and reusable. It is also cheap to produce.

Concrete is also popularly used in order to make a structure more energy-efficient. Insulating concrete form (ICF) is a permanent structure that is put together just like Lego blocks and are interlocked together. When the pieces have been interlocked, the structure will then be filled with wet concrete. As a result, a very strong and energy-efficient structure is produced. But this one can be a bit more expensive than others. However, there is no question that a concrete home will not only be cooler in summer and warmer during winter, but it also takes lesser energy to cool and heat the home, thus giving you more savings in the long run. Here are some more of its benefits.

  •        ICF formwork produces very minimal air leaks which improves comfort while reducing heat loss.
  •        It has a high thermal-resistance
  •        It is up to 10x stronger other traditional wood frameworks

Indeed, the world of formwork, especially the concrete type has taken big leaps and bounds of positive comments in the last 1,000 years. The history of concrete dates back to the time of Romans and Egyptians when they used concrete in different forms for their buildings and infrastructure. This concept has actually been around since 125 A.D.

The Roman Pantheon for instance, is an iconic structure in history and one of the very first structures to have used formwork (concrete) in its construction.

And today, the world of concrete has made several advances and improvements, thus the rise of the massive and structures that we are benefitting from today. Few more years from now, this material will for sure be instrumental in more massive structures that will greatly change our lives.
