Application

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

Description

SECIL NHL 5 is an eminently 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 5according to the NP EN 459-1:2010. CE marked to EN 459-1:2010.
