Cinvestav team investigate blended cement made from volcanic ash

Mexico: A team led by José Iván Escalante Garcíaat at the Saltillo unit of the Center for Research and Advanced Studies of the National Polytechnic Institute (Cinvestav) is researching the use of volcanic ash in making blended cements and concrete. Volcanic ash is being considered to reduce the clinker factor of cement due to its abundance, low cost and its appropriate chemical composition. A clinker substitution factor of up to 80% has been achieved using volcanic ash. The research group has developed 15 alternatives to Ordinary Portland Cement (OPC) using waste or materials or minerals.
