Even the casual onlooker knows how durable concrete is. After all, we have walked past concrete buildings that have lasted years and years – even millennia in the case of some structures from the Roman era. But why is concrete so durable and able to resist even centuries of weather and erosion, and is there anything we can do to help the process?
Resistance to Humidity
One factor that allows concrete to last in humid weather is its lack of organic components. Because there is nothing to rot or decompose, unlike wood and other materials, it is very difficult for moisture to penetrate concrete except through joints between sections. Concrete can also breathe, which means moisture can easily escape, as well, which helps prevent water from causing long-term damage to concrete structures.
Cold weather is another one of the biggest threats to concrete as the ice and freezing temperatures wage war on concrete surfaces every time winter rolls around. Concrete in generally warm climates tends to last much better. This is one of the biggest reasons that many Greco-Roman and other ancient structures have lasted in moderate areas where temperatures don’t typically create these cold weather cycles. However, in colder climates, it’s important to use a concrete mixture that can accommodate the freeze and thaw cycles of the winter months.
Resistance to Sulfates and Salts
Concrete is also capable of long-lasting performance in areas where salt or sulfates are a concern. For example, sulfates and salts can react with matter in concrete, especially in locations that experience numerous cycles of wetness and dryness. However, as with ice, using admixtures and low water to cement ratios in the concrete can make it more able to resist this damage. In fact, concrete is often used for concrete in saltwater with great success due to the use of minimally permeable concrete poured with a low-water cement mix.
