Natural hydraulic lime (Lencal)

Natural hydraulic lime (Lencal)

Natural Hydraulic Lime is made in an entirely natural way, from the firing of clayey limestone [marl] and without any type of chemical additive. Made up mostly of calcium silicates and aluminates and calcium hydroxide. The stone is fired at temperatures between 900 °C and 1100 °C. Subsequently, a slow and careful process of hydration of the stone is carried out to end up obtaining a product.

The method of manufacture of LENCAL Natural Hydraulic Lime (NHL-2) allows us to be a product with low CO2 emissions, which leads to a better preservation of the environment.

USES AND APPLICATIONS


Natural Hydraulic Lime is the natural binder used in old constructions for the realization of foundations, vertical faces with bricks, walls, etc.

Natural Hydraulic Lime has a wide range of applications, from the preparation of mortars and concrete, to its application for the realization of asphalt, precast or soil stabilizer.

FEATURES


Natural Hydraulic Lime has exceptional characteristics, a consequence only of the adequate composition of the raw material. Contains no additions.

Hydraulic setting by chemical reaction of its own components, which provides excellent short-term resistance.

Compatibility with old building methods and materials from a chemical, structural and mechanical point of view.

Volume constancy under variable humidity conditions.

Less expansion, weak retraction and greater flexibility under certain mechanical conditions, which favors the adaptation to the deformations of the support without causing cracking.

Better sealing against physical attacks (vibrations, wind, freeze-thaw cycle) and chemicals (rain, acid salts, etc.).

It does not produce efflorescence because the lime it contains has been manufactured with high quality raw materials and without additions.

Greater structural stability due to the self-sealing of the cracks: the mortar absorbs water dissolving the hydrated lime that penetrates the voids and cracks where it is carbonated to seal them.

Excellent adherence to the substrate due to its fineness and water retention that maintains its basic pH (> 12) for a longer time.
