5. REISSUE (July 1989) with Amendments No. 1, approved in March 1989 (IUS No. 7 1989)

Construction materials produced and put on the market must comply with certain technical and quality parameters, which are created and regulated at the state level.

To achieve these goals, GOST standards are created, each of which describes the main characteristics of the selected building material and standards for compliance. Construction lime is regulated by GOST 9179 77. The technical act establishes the specifics of this material.

As you know, it is a product of firing rock composed mainly of natural elements or its mixture with special components of mineral origin.

Classification

The white substance obtained by burning limestone is separated depending on the solidification conditions. This is how it happens:

with elements of air. Provides hardening of mortars for construction and concrete, while maintaining their original characteristics. proportions of cement-lime mortar for plaster;
with hydration with components. They ensure hardening of building concrete mortars, while maintaining their original strength regardless of the environment. proportions of cement mortar. It can be air or water.

In turn, there is a classification of quicklime with air layers, depending on the percentage of calcium and magnesium oxide that it contains.

It goes on the market:

with calcium components;

with magnesium components;
with dolomite components.

Lime with air layers can be divided into those that are not slaked and hydrated (slaked).

The latter is obtained by quenching the components discussed above. The hydraulic white substance that is obtained by burning limestone can be divided into:

weakly hydraulic;
highly hydraulic.

According to the structure of the fractions, lime, which corresponds to GOST 9179 77, is divided into:

lumpy;

crushed;
powdery.

Powdered material is obtained by crushing and grinding, and then quenching the lump of potassium oxide. Ultimately, a chemical mineral component may be added to the mass.

The unslaked white substance obtained by burning limestone is classified according to the degree of slaking.

Lime is divided into those that are slaked very quickly - no longer than 8 minutes, at an average pace - from half an hour, very slowly - more than half an hour.

Quality control

Potassium oxide is controlled by the department that is responsible for technical control. It is created in every company. Happening acceptance and shipment of material in batches, while their size depends on the productivity of the enterprise for 12 months.

Quantity measured:

two hundred tons - with a productivity of up to one hundred thousand;
four hundred tons with a productivity of one hundred thousand to two hundred and fifty thousand;
eight hundred tons – from two hundred and fifty thousand;

Reception and unloading of batches and smaller masses can be carried out. The mass of the material supplied must be determined by weighing the lime in transport using a special device to determine it. Such devices can be of railway or automobile type.

Mass material that is shipped in ships, easily determined by shrinkage. Acceptance and certification of goods is mandatory. The type and type of potassium oxide is indicated based on information provided by the company's process control department.

Magazines with information on flow control that are used when receiving goods must be numbered and sealed accordingly by the enterprise.

Technological control of all production stages carried out at the plant is carried out in accordance with special regulations.

Current quality control of goods that are shipped is carried out according to information from testing data from general samples, which are compiled during the work of several shifts. Materials for the sample are selected.

Lump lime is from equipment that regulates the supply of goods to warehouses. The total sample taken is no more than two tens of kilograms. For material in powder form - from each place of production, with a total sample of ten kilograms.

Disposable materials for tests are selected evenly and in equal quantities. General tests of lump material should be crushed until centimeter particles are formed. The samples that are taken for in-line control of the batch that is shipped are thoroughly mixed.

Then they are divided into equal parts. Some of them are necessarily tested to determine standard indicators, others are placed in a vessel where air does not enter. It is immediately sealed and stored in a room with low moisture concentration in case control tests are carried out.

A control test to determine the quality of the material is carried out by special inspections. They can be both state and departmental. It can be carried out by the consumer himself if he has the appropriate skills and strictly follows the sampling procedure.

An element is selected from each batch for testing, which is obtained by combining and thoroughly mixing all collected materials.

For lump lime for tests it is worth collecting three dozen kilograms, for powdered form - half as much.

When all the lime is shipped simultaneously, the material for study is selected at the loading or unloading stage. In the latter case, it is taken from the bags, or already at the unloading stage, when the buyer begins to use it.

If the material in question is supplied in bulk on special trains, a sample is taken in equal parts from each car. If potassium oxide is delivered by car, the test is collected in equal parts from all containers that exceed thirty tons.

If potassium oxide is supplied in bags - in equal parts from ten bags, which are selected at random. If potassium oxide is supplied by ship, from a conveyor belt or other loading and unloading mechanism.

When the material for the general test is selected, it is being studied to determine the indicators provided for GOST 9179 77. At the quality test stage, potassium oxide must comply with all the norms of the described standard.

Trial

Chemical studies and determination of physical and mechanical characteristics of potassium oxide are carried out according to the prescribed standards in GOST 9179 77. Lump material is shipped in bulk.

Lime in powder form is shipped in bulk or sorted into special containers. If the client agrees, the use of paper bags with four layers of paper is allowed.

To determine the average gross tare weight, twenty bags are weighed at the same time and selected at random. The resulting number is divided by 20.

The average net tare weight is determined by subtracting the average net number of the bag from the gross number.

It is allowed to deviate from the average values of bags of net lime from those indicated on the container. This number cannot exceed one thousand grams.

The manufacturer, at the same time, with the details and information for shipment, must convey to each buyer the quality control asport, where it must be indicated:

at what enterprise the product was manufactured;
when the potassium oxide was shipped;
party and passport number;
weight of goods sold;
when was the extinguishing carried out and at what temperature;
how many minerals and other elements were added;

For each transported unit, a label is inserted, which states: the name of the company, the name of the product, its guaranteed type and grade, a description of the standard according to which the delivery is carried out.

If the material is shipped in paper containers, it must indicate:

what is the name of the company;
what is the name of product, type and grade;
description of the standards according to which the delivery is carried out.

The manufacturer must deliver the goods by transport, while preventing moisture from entering. Ingress of moisture is undesirable when storing materials.

Potassium oxide can be transported regardless of the type of covered transport in accordance with the standards for transporting such substances that apply to it.

GOST 9179 77

Today, the material in question, which can be extracted by firing, is actively used as the basis of cement. This became available due to the material’s ability to perfectly absorb moisture.

This material is in demand at the stage of production of slag concrete components, products with coloring pigments, and white bricks. its size. Quicklime is also used for decorative plaster. you can see its application.

Quicklime is actively used to neutralize wastewater and to treat buildings.

It can be found in most food products on the market. It is hidden in the form of substances that ensure the creation of emulsions from immiscible liquids, binding components that, due to their chemical and physical properties, resist dissolution in each other: for example, liquid and oil.

Quicklime has the following technical characteristics. its formula. Potassium oxide manufactured in accordance with GOST standards in accordance with technological regulations, which is approved in the manner established by regulatory legal acts.

Materials that are used at the production stage of potassium oxide: sedimentary rocks consisting of carbon dioxide salts, inorganic natural and artificial materials with hydraulic and (or) pozzolanic properties. All these components must comply with GOST 9179 77.

Construction lime and its technical conditions are also discussed in this document. Quicklime with air gaps without the addition of other foreign elements is divided into three types. about application.

Quicklime in powder form with different mineral components - into two grades; hydrated (quenched) without and with special additions - into two grades. its formula. Hydrated potassium oxide cannot be wet, this figure is 5 percent. The type of potassium oxide is determined by its indicative components, which correspond to low grades.

The percentage of hydration water in the quicklime type material cannot be more than two percent, and the maximum particles of crushed material cannot be more than 2 cm.

For more information about quicklime, watch the video:

Slaked lime (also called hydrated lime) is produced by contacting it with water. about its application.

This, in turn, completely changes the chemical and physical characteristics of the material, releasing excessive heat in the form of steam. If you pay attention to the type of slaking, the result can be: lime water, milk or fluff.

Application

Lime GOST 9179 77 is used:

in fertilizers. They have been used for many years to increase soil fertility and for liming, in other words, reducing the degree of acid content. Lime fertilizers from hard rocks are crushed before being applied to the soil.;

for soil and plant cultivation. Water with potassium oxide is mixed with copper sulfate and after a few hours they begin to treat the plants and soil against pests;

when whitewashing wall and floor coverings. Completely different proportions are already used here, a kilogram of lime is diluted with two liters of water. If necessary, you can add a little more water until you reach the desired consistency.
