Replacing Portland Cement with Calcium Alumino-Silicate Glass: How Much is Possible?

Explanation:

The percent of Portland cement that can be replaced by Calcium alumino-silicate glass depends on various factors, such as the specific application and desired properties of the cement. However, in general, Calcium alumino-silicate glass can be used as a partial replacement for Portland cement.

For example, in a study published in the Journal of the American Ceramic Society, researchers found that replacing up to 20% of Portland cement with Calcium alumino-silicate glass resulted in improved mechanical properties and reduced energy consumption during manufacturing.

It's important to note that the exact percentage of replacement may vary and should be determined through careful testing and analysis to ensure the desired performance of the cement.
