DESCRIPTION
Our DRAGON BM-QL is a medium-high strength cement, designed principally for the ready mix concrete and dry mix mortar industry.
Natural pozzolanic addition increase long term concrete compressive strength, improve chemical resistance and reduce expansion effects due to alkali reaction.

ENVIRONMENTAL NOTE
In this product, the reduction in clinker content means a reduction in CO2 emissions of 16% compared to those of the same resistance category and 25% compared to CEM I type cements.
This reduction does not affect its performance. It has an Environmental Product Declaration.
