Application

In the production of mortars, as the only binder or mixed with other hydraulic or non-hydraulic binders, giving them workability and flexibility, significantly reducing retraction in hydraulic mortars (e.g. masonry, rendering and finishing mortars). In the production of rehabilitation mortars, as the only binder, for the execution of internal and external renders, over ancient substrates.

Description

SECIL NHL 3.5 is a moderately hydraulic binder composed in its majority by calcium silicates, aluminates and calcium hydroxide. It is obtained by the burning of marlstone, followed by grinding.It is classified as NHL 3.5 according to the NPEN 459-1:2010. CE marked to EN 459-1:2010.
