Cuba: Corporacion Cementos Cubanos’ Siguaney plant produced over 90,000t in 2020. Centrovision News has reported that the plant produced 87,000t of grey cement and 3000t of white. It had planned to produce 10,000t of white cement, but still exceeded its cement target overall. Cost per tonne of cement was also lower than planned.

The company said that grinding operations were disrupted when the Cienfuegos cement plant delivered less clinker than expected. As a result, the Siguaney plant’s kiln produced 18,000t of additional clinker. It achieved this through the use of refractory bricks from another kiln. Disruptions to imports also caused the company to hire Cuban Lubicrants Company (Cubalub) to provide lubricants for the plant’s compressors.

The producer said that it foresees no increase in cement production in 2021. It will launch two new pozzolanic cements, PP-35 and PZ-25.

General manager Gonzalo Reina said "PP-35 and PZ-25 have similar benefits to other cements, but their constitution saves clinker, a raw material that generates the greatest cost and constitutes the greatest difficulty in maintaining stable production.”
