A research team at MIT has discovered a new formula for portland cement that makes it twice as resistant to fractures as normal cement, but also less energy intensive. According to a recent Jetson Green article:
The team of MIT researchers now discovered that by reducing the ratio of calcium to the silicate-rich clay in the current formula, led to a reduction of carbon dioxide emissions by nearly 60 percent, which is quite a significant number. They found that the optimal ratio of calcium to silica is 1.5, while the current standard ratio is 1.7.
The team also discovered that the concrete made using the new formula is twice as resistant to fractures as normal cement, which according to the researchers is the result of its molecular structure, which is not the traditional tightly ordered crystalline, but a more disordered glassy structure.
Testing on a practical-scale is expected to be the next step. Will it work? Read More
