DESCRIPTION
Our DRAGON SR is a medium-high strength cement, designed specially foruse in sulphate-aggressive conditions, both in ground and in water, and marine environments.
Its main features are:
• Low tricalcium aluminate content.
• High final strengths.
• Low fineness, permitting a reduction in water demand.

ENVIRONMENTAL NOTE
Since 2009, at our factory in Sant Vicenç dels Horts (Barcelona), the implementation of new technologies in the production line, the use of alternative fuels, and improvements in the use of additions and grinding additives in our cements have allowed us to achieve a significant reduction in CO₂ emissions.
In this Portland cement, CO₂ emissions have been reduced by 5% per ton, calculated for Scope I and compared to our reference cement CEM I 52,5 R from 2020.
This cement is manufactured with clinker aligned with European taxonomy.
