RC ASTIVO

RC ASTIVO is a hydraulic (NHL 3.5) colored lime for the preparation of a pointing mortar in accordance with ENV 459-1. Lime mortars for lime pointing are generally softer and more porous compared to mixes using cement therefore allowing moisture to evaporate from the joints more freely. This can help to lower moisture levels in the wall and reduce the build up of soluble salts in the stone face, therefore reducing potential damage or ‘spalling’ of the masonry. Lime pointing of traditional masonry using lime mortar based on lime putty or natural hydraulic lime (NHL) offers many advantages over cement based mortars.

Elasticity/deformability

RC ASTIVO is much more elastic and deformable compared to a hybrid or cement mortar. This is an essential factor, as it minimizes shrinkage and tears and allows small movements to be absorbed.

‍

Permeability and insulation

RC ASTIVO gives the building an excellent vapor permeability, which prevents the formation of condensation moisture, mold and damp spots. Moreover, the insulation value improves, in other words healthier living.

Mechanical strength

The mechanical characteristics are built up progressively: NHL 3.5 lime reacts with water and then hardens under the influence of the air (carbonation). Soil consolidations in the building are absorbed better. Due to the free lime that carbonizes over a long time, a mortar also has a self-healing property.
