KEY POINTS
-
Construction materials evolve with health, environmental, and regulatory shifts, replacing hazardous options like lead piping with safer alternatives.
-
Technological innovations in alloys, polymers, and nanomaterials enhance strength, durability, and efficiency.
-
Economic forces, including tariffs on key metals, shape material selection and investment priorities, sometimes diverting resources from sustainability goals despite incentives.
Organic Shifts in Material Use
It is natural that over time, there are evolutionary or what might be termed organic changes in the materials going into construction projects. Some shifts derive from an understandable desire to reduce or eliminate negative health concerns. For example, where once lead piping was popular everywhere, it has been replaced by PVC or plastic piping.
Technological Advancements Driving Material Innovation
Technological advances are also primary drivers of construction material innovations. Certain alloys and other additives, acting in concert with raw steel, aluminum, and cement, go a long way towards corrosion protection and extending lifespans.
Also, there are new types of structures that are economically viable only thanks to their novel employment of existing but relatively fresh-on-the-scene materials. An easy example to cite is the polymers that coat the blades on the towering structures that make up wind farms.
Economic Pressures and Tariff Impacts
Plus, external economic factors can pack a wallop and play an important role. Obviously, at present, there are the cost consequences of the exorbitant tariff structure attached to the usage of steel, aluminum, and copper.
A problem tied to copper, relating to its usage in electric circuitry, is that its major alternative is aluminum, similarly under a tariff muzzling. The latter has a significantly lower (60%) degree of conductivity, making it less ideal for most uses. But it is lighter, giving it a better conductivity-to-weight ratio, making it the premier choice for some specific applications such as the high-in-the-sky wiring that carries direct current from tower to tower in long-distance transmission lines.
There’s another way in which the tariffs promote a possibly unintended consequence, depending on Washington’s overarching objective. They set up a competition of purpose with respect to capital spending. Their intent is to promote domestic investment in capacity additions. Such investments will eat into the dollars that would otherwise have gone into green initiatives.
Advanced Materials and Alternatives Driving Construction Innovations
Many steel, aluminum, and concrete firms have lately been directing their spending efforts to ultimately achieve zero carbon emissions. Reducing these initiatives will render U.S. companies outliers versus what their competitors in other countries globally are doing.
Multi-walled carbon nanotubes beat copper for both lightness and electrical current conductivity. They are also inordinately strong, more so than steel and Kevlar.
Mass timber is making a bid to be the wall, floor, ceiling, and load-bearing substitute for steel and cement in building construction projects. The selling points laser in on sustainability and the potential for prefabrication. The subset products all see dimensional lumber bonded together. Glulam has grains running parallel; cross-laminated (CLT) has grains fashioned perpendicularly; and nail-laminated (NLT) and dowel laminated (DLT) are obvious in how they are tied together.
Finally, kudos should be awarded to the Green Building Council. The GBC’s groundbreaking work to encourage owners and contractors to strive for silver, gold, or platinum LEED (Leadership in Energy and Environmental Design) certification for new buildings has provided a major incentive for innovation by building material manufacturers.
