Hydrated Lime - how to use it properly ?

svezhegashenoy lime - how the process?

Lime refers to the binder materials that are commonly used to prepare solutions of different nature.All such materials are divided depending on the curing environment.Thus, referring to the group of hydraulic binding materials cement hardening process starts and continues in the water in the water.This environment does not blur it.

usual, widely used lime refers to a group of air.Hardening occurs only in the air, the water dilutes it.Building lime is quicklime lump can be called quicklime, or ground.

extinguished lime dough or powder lime, is often added to dry backfill, as a reliable means of protection against pests (insects and rodents).Maturing in the dough, it is well and without limitation as to time is stored in special pits.At the same time, with the quality of the test is only growing.In contrast to the test, ground quicklime should be used within one month from the date of preparation.

process of extinction, according to the desired type, carried out in the open and clean space for fluff (per tonne of lump lime should be seven hundred liters of water) or in tvorilnyh tanks (pits or boxes).Nuances dependent quenching process speed: the heat released in the course of its production, water is added portionwise, so as not to lower the temperature.

The resulting dough is diluted with water until thick milk and drained into the pit tvorilnuyu.Svezhegashenoy lime can be composed of residues: unburned pieces or burnt through the feedstock.They are collected in a separate box and re-fill with water to extinguish.After this the remnants are ejected.

Hydrated lime - use and possession

To reduce the resulting density of hydrated lime in water is added to it.Contents mixed, actions are repeated to until the composition no longer take water.Last added water to disappear from the surface of the lime.Then the composition is filled with fine sand dropout, a layer of not less than twenty centimeters.

To prevent the dough from freezing in winter on top of sand laid at least seventy centimeters of the ground.Prepared in this way the pit is marked with fences and held until the final extinction of the smallest particles.In the case of unacceptable blistering and cavities may occur in solutions of outstanding grains.

That slaked lime, the use of which is planned in solutions for masonry, maintained in this manner for at least two weeks.If the resulting dough intended for use in solutions for plastering, the exposure period is increased at least up to a month.

number obtained after the quenching test largely depends on the quality of raw materials.First-class quicklime can provide more than two liters thick dough with each kilogram of their weight.With a decrease in quality of the output is reduced, respectively, for two and a half liters per kilogram of the second and third kinds.

Generally, mortars are mixtures of binders, fillers and water, most commonly lime mixtures prepared from dough, sand and water.They are used for masonry oven (base and tube).Generally, such solutions are characterized by high adhesion to the brick, cinder surfaces.For use on wood shingles need to pre-fill or special plaster grid.

As dissolve hydrated lime - simple rules to note

To prepare the solution, before being diluted with hydrated lime, sifted sand in the right quantity.The dough is added to water, the composition is mixed, it gradually in batches poured sand and mixed thoroughly each time.The resulting solution is filtered through a sieve (for greater uniformity and fines removal).

disadvantage of pure lime mortar is a long time curing.For greater speed of the added gypsum or cement.The setting time is greatly reduced.For solutions with additives gypsum time - four minutes after the addition of water.Much slower harden solutions with cement additives.

But not only used in the compositions discussed solutions.Until now, use of antiseptic properties.Lime wash is widely used in offices and business premises for the protection of the trunks of trees, etc.In this case, slaked lime consumption is about 0.3 kg to cover the square meter in a single layer or half a liter of liquid whitewash.

Defines the types and properties, which should have lumps and slaked lime, GOST of 1979 №9179-77.Under its terms, classification of building lime includes air and hydraulic types.Depending on the composition of the oxide inclusions, distinguish calcium, magnesia and dolomite.Detailed description of product mix requirements known for the quality, production processes, packaging and delivery of the material.
