21 May 2018: Technical visit in Portugal

LC3-technical visit

21st May 2018

Lisbon, Portugal


LC3 is a new cement composed of Portland cement, calcined clay and limestone with clinker content around 50%. Kaolinitic clays with kaolinite content above 40% are suitable for the manufacture of LC3.

Clay calcination is a key process to produce LC3. Clay has to be calcined at around 800oC until the material is fully dehydroxilated, and then it becomes activated. Calcination takes place at a rotary kiln.

With a wealth of expertise in the area of clay processing IPIAC is a leading company in the development of clay calciners. Their products are simple, robust and affordable. The tour to IPIAC’s manufacturing facilities will provide visitors with direct access to the technical team designing and manufacturing the product and evaluate the different choices of technology available.
