The calcium oxide we manufacture has a high reactivity index, ideal for certain industrial processes, due to our know how, calcination process & quality checks. These factors set us apart from other products on the market.
In asphaltic concrete and bituminous materials, the replacement of the filling elements or load (filler) with appropriately dosed lime improves the water resistance of the firm, reduces aging and cracking. The affinity of lime with bitumens and aggregates strengthens the bonds inside the structure. The result is a homogeneous asphalt layer, compact, durable and without cracking problems.
An unstable clay soil treated with lime changes its physical properties and is transformed into a stable and durable plate. Lime profoundly modifies the physical characteristics of the soil, decreases the liquid limit and the plasticity index. Increases plastic limit, CBR and compressive strength. Its high index of pozzolanic receptivity makes it possible to transform the inert components, agglomerates the fine particles of clay and transforms a highly plastic soil into another very stable one. Ionic exchange (Ca++ / Na + H+) and the formation of silicates (3CaO. SIO2 ; 2CaO. SiO2) are the fundamental reactions.
Lime hydration also plays an important role:
CaO + H2O –>Ca(OH)2 + 278 Kcal/Kg CaO.
Wet soils dry out when lime is added and this increases their yield strength.
The sub-base and base layers stabilized with lime constitute a barrier resistant to both superficial and capillary water. The floors are resistant to frost and construction delays due to rain are reduced.
A high value of the specific surface area and a percentage of useful CaO above 90% are fundamental for its good behavior next to well-classified granulometries.
They are obtained with 10% quicklime and 90% silicon-rich sand. They are moistened by pressing lime with sand and water. Hardening takes place with steam under pressure in autoclaves and finally they are cooled in air, producing their carbonation.
In silica-limestone bricks, the use of lime activates the pozzolanic reaction with silica sand and clay, producing bricks with high mechanical and thermal performance.
Lime mortars are durable, withstand climate changes and have a high water retention capacity.
Lime is a particularly suitable material for the finishing and decoration phases of mortars, plasters ready to be used (plasters), whitewash and the creation of fresco supports.
Its color, plasticity, adhesion, workability, the polished surface that allows you to reach, give relief to facades and walls.
Recarbonation in the air allows the wall to breathe to evacuate the always inevitable moisture.
Lime, in general, is the main ingredient in a mortar and is the oldest cementing material known.
