While fly ash and Portland cement are the big dogs in terms of raw materials for adding to cement, there are other alternatives ready to make a name for themselves.

Silica fume

This fine, glass-like powder is collected from electric arc furnaces. This multipurpose concrete mixture is made of water-soluble particles. These particles chemically react during the hydration process and fill space in between grains of cement. This makes the cement denser and less permeable to moisture. Silica fume also improves the bonding strength of other materials in a batch.

 Ground granulated blast-furnace slag

As a Portland cement alternative, this glassy material is produced as a by-product of the iron and steel making process in blast furnaces. It is slow to harden, but it does develop very durable concrete.
