New supplementary cementitious materials
The search for new supplementary cementitious materials (SCMs) is ongoing. A recent review of existing SCMs and the potential for new ones caught the eye of Arthur Harrisson and provided further potential for investigation.
A disused slate quarry: a potential SCM?
A recent review1 of the availability of supplementary cementitious materials (SCMs) and the possibility for expanding the choice of those available examined the range of emerging SCM sources and also the means of testing the suitability of different materials. The materials considered fell into five general categories:
1. natural SCMs
2. calcined natural SCMs
3. LC3 materials
4. by-product materials – ashes and glasses
5. by-product materials – slags
