A few years ago, I stood in a concrete batch yard in the Midwest, watching a load of our standard high-strength concrete sit in a rail car, waiting to be delivered to a highway project. The temperature that day hit 102\u00b0F\u2014unusual, even for summer there. By the time the concrete arrived at the site, its slump had dropped 3 inches, a problem that would\u2019ve forced the crew to add extra water to get it to pour right. That extra water? It weakened the concrete by up to 15%, according to tests we ran later. That moment stuck with me, not just as a supplier but as someone who\u2019s spent 18 years building things that last. For construction materials, climate change isn\u2019t some far-off environmental buzzword\u2014it\u2019s a daily, physical shift in the raw materials, chemistry, and rules we work with. Construction Materials<\/a><\/p>\n

<\/p>\n

Let\u2019s start with the basics that most folks don\u2019t talk about: the core ingredients of our products are changing, because the earth is changing. Take aggregate, the sand and gravel that makes up 60-75% of every cubic yard of concrete. Two years ago, a wildfire in Northern California burned through a major river system that\u2019s been our aggregate source for decades. The debris from the fire\u2014ash, burnt soil, large rock fragments that don\u2019t meet gradation specs\u2014clogged the river beds. We had to bring in aggregate from a source 200 miles away, and those extra transportation costs got passed on to every project we served that quarter. Wildfires aren\u2019t the only issue here. Heavy rainfall events, which are 50% more frequent in the U.S. since 1950, according to the EPA, wash sediment into river beds too, making aggregate extraction slower and more expensive. In the Southeast, recurring droughts have dried up local sand pits, forcing contractors to import sand from overseas\u2014only to hit customs delays because of new environmental rules that restrict low-quality imported sand. Even steel, the backbone of most commercial construction, is feeling this. Iron ore mines in Minnesota, a key U.S. source, have seen more frequent thaw-freeze cycles that damage rail lines, delaying deliveries of raw iron to mills. We\u2019ve had steel orders delayed by 3 weeks on average since 2020, simply because a rail line was washed out in a spring storm. This isn\u2019t just an inconvenience\u2014it\u2019s a hit to project timelines, which means builders are rethinking how they specify materials.<\/p>\n

Next, the performance of materials when they get to a jobsite is changing, and that\u2019s where we see the most immediate impact. Concrete, as I learned that hot summer day, is highly sensitive to temperature. When air temperatures stay above 90\u00b0F for days, cement hydrates faster, which means the concrete sets before crews can finish pouring and finishing it. But it\u2019s not just high heat\u2014extreme cold is a problem too. Last winter, we supplied precast concrete panels to a residential tower in New England. A week of sub-zero temps meant the curing time was extended by 48 hours, and we had to add an extra set of curing compounds to prevent cracking. The panels arrived on-site, but the crew couldn\u2019t install them on schedule, pushing back the entire project. Even asphalt, another big product for us, is tricky now. Paving crews work best when asphalt is between 275-300\u00b0F; if temperatures rise above 85\u00b0F during paving, the asphalt cools too fast before it can be compacted properly. We\u2019ve had projects turn us away because they couldn\u2019t find a window of cool enough weather to lay asphalt. But wait\u2014what about long-term performance? Materials that are supposed to last 50 years or more are deteriorating faster because of shifting weather patterns. A study from the National Institute of Standards and Technology (NIST) found that concrete structures in the South are suffering 20% more freeze-thaw damage and 12% more corrosion from de-icing salts, because winter temps are now more variable\u2014days above freezing followed by sudden cold snaps. Steel beams in the Northeast rust 30% faster than they did 20 years ago, because increased rainfall and humidity from hurricanes and nor\u2019easters are speeding up oxidation. Even wood products, though I don\u2019t supply those, I\u2019ve seen what it does to projects: lumber warps more when there\u2019s more extreme humidity, and termite infestations are rising because warmer winters let pests survive farther north.<\/p>\n

So what are we doing as a supplier, not just to adapt, but to help our customers adapt? The old way of sticking to one product line and one source is dead. Three years ago, we launched a line of low-carbon concrete mixes specifically engineered to handle temperature extremes. We use a blend of fly ash from coal power plants, ground granulated blast furnace slag (GGBS), and smaller amounts of Portland cement\u2014this reduces the carbon footprint by 25%, and crucially, it\u2019s more heat-resistant. We\u2019ve tested these mixes in 100\u00b0F heat, and their slump loss is cut in half, so crews don\u2019t have to add extra water. We also partnered with a quarry in Idaho to develop a stockpile of aggregate that\u2019s been processed to handle higher temperatures, with better gradation that helps concrete cure more evenly. For steel, we started working with domestic mills that use electric arc furnaces (EAFs) instead of traditional blast furnaces. EAF steel produces 70% less carbon emissions, and the mills are located closer to key construction hubs, so we can get deliveries 2 days faster. That\u2019s a big win for timelines when weather is messing up transportation.<\/p>\n

We\u2019re also investing in testing and customization. Last year, we set up a mobile lab that can come to jobsites and adjust material mixes on the spot, based on real-time weather data. If a job is in Phoenix where the temp is hitting 105\u00b0F, we can tweak the concrete mix to add set retarders and fine-tune the aggregate size, so it pours and cures correctly that day. In Seattle, where rain is more frequent and humidity is higher, we adjust our asphalt mixes to be more water-resistant, so they don\u2019t develop potholes after a single heavy storm. This isn\u2019t one-size-fits-all anymore\u2014every project\u2019s material needs depend on where it is, what the weather\u2019s going to do that week, and how long it needs to last. We even work with architects and contractors during the design phase now, not just when they\u2019re placing an order. A hospital being built in Florida? We don\u2019t just supply steel and concrete\u2014we advise them on using corrosion-resistant rebar, because the salt air from hurricanes and heavy rainfall will make regular steel rust faster. For a school in Minnesota, we recommend precast concrete panels that are thicker and cured with special compounds to handle extreme freeze-thaw cycles, so the school will last for decades without needing major repairs.<\/p>\n

The biggest challenge we face is the uncertainty. No two years are the same\u2014last year was a wet year in the Midwest, this year it\u2019s been droughty. Last summer was way hotter than average, the summer before was mild. We can\u2019t plan for every weather event, but we can build flexibility into our supply chain. We keep three stockyards across the country, so if one area is hit by a storm or a fire, we can shift materials to another stockyard to meet demand. We also work with small, local suppliers whenever possible, because they\u2019re more resilient to weather shocks than big, faraway operations. A sand pit in Ohio might have a smaller output than one in Michigan, but if Michigan\u2019s pit is closed due to flooding, Ohio\u2019s can pick up the slack.<\/p>\n

I know a lot of builders out there are frustrated. They\u2019re dealing with rising material costs, delayed timelines, and materials that aren\u2019t performing like they used to. Climate change isn\u2019t going away\u2014if anything, these shifts are going to get more extreme over the next 10 years. As a construction materials supplier, my job isn\u2019t just to deliver concrete and steel. It\u2019s to be a partner that helps them navigate this new reality. That means listening to their problems, testing new materials, and being transparent about what\u2019s coming. A few months ago, a general contractor called me panicking because a rail line carrying their steel order was washed out. Instead of saying \u201csorry, we can\u2019t help,\u201d I reached into our other stockyard and got them a shipment of EAF steel from a mill in Pennsylvania, delivered in 48 hours instead of the usual 7 days. It cost us a little extra, but it saved their project. That\u2019s the kind of partnership that matters now.<\/p>\n
