Some of the files are quite large and could take some time to download with slow ADSL as in Australia, so please have patience
We are constantly updating web pages, writing papers and preparing presentations as there is so much to communicate and so much misinformation to correct. We take responsibility in relation to some of this misinformation as we were wrong in the early stages about strength and the carbonates that form for example. Please be cautioned that we have since made many corrections. Our web pages have usually the most up to date and certainly much more authoritative about our cements than other sources. Also be cautioned that original papers and presentations have not be altered however there are most likely later versions on the same or a similar subject with more correct information. Please refer to and quote only more recent papers!

[1] Reactive magnesia (rMgO) is also variously known as caustic calcined magnesia, caustic magnesia or CCM. The temperature of firing has a greater influence on reactivity than grind size as excess energy goes into lattice energy.
Technical information about reactive magnesia is available in the technical area of our web site.
