New analysis of sugar ash substitution in cement

Many of us in North America are familiar with the use of fly ash from coal fired power plants in cement, but many parts of the world have a much more prevalent source of ash for cement – sugar production.  A number of facilities in Asia and South America have large supplies of sugar waste ash available.

Now, from the Niels Bohr Institute in Copenhagen comes news reports of a detailed study of the bonding between water, cement, and ash in a mixture.  Overall, the mixture resembles many pozzolanic cements utilizing other flyashes, with a substitution of approximately 20% of sugar waste ash for cement.   This opens up another ash source for use in cement mixtures in developing parts of the world.
