Photo: Radio Rebelde The start of the industrial production of the ecological cement at the Siguaney enterprise made headline in the central Cuban province of Sancti Spiritus, for that cement with low carbon content that is now being packed in sacs and produced in bulk, is mainly destined to other works of construction which are being carried out nationwide.

The new chemical formula was designed by a team from the local Center of Researches and Development of Structures and Construction Materials of the main University from Villa Clara province. The team is directed by PhD. Jose Fernando Martirena Hernandez.

“Today is a historical day as we have achieved for the first time the fact of including this type of new cement into the industrial production. It is a new type of cement due to its chemical formula and it allows tripling the levels of replacements of the Klinker element with a common practice in the Cuban cement industry. Therefore, this places our local industry among the first of its type in the world in terms of innovation.” Martirena Hernandez pointed out.

Martirena Hernandez alsos explained that, “the substitution of the Klinker element for the local Matacaolin one with carbonate of calcium allows a considerable saving in terms of energy given the fact that it reduces the costs up to 28% which means $ 32.00 dollars by each ton of cement produced.” / Source: Radio Rebelde / Translated by: Juan Carlos Caballero.
