Higher concentrations of carbon dioxide in our atmosphere accelerate the deterioration of concrete. As CO2 penetrates a structure, it reacts with already present moisture and calcium hydroxide, progressively eating away at the layer of cement covering steel reinforcements, leaving them vulnerable to rust.
Fortunately, an environmental scientist in the Netherlands has invented a self-healing version. The concrete is embedded with nitrogen, phosphorous, calcium lactate, and a limestone-producing bacteria.
The additives lie dormant until a fissure emerges, admitting air and moisture. At that point, the bacteria activate, feed on the calcium lactate, and convert it into limestone to seal the split in the concrete.
