Granite grace marks
The stabbed granite’s strength reaches M 1400, the stroke indicator. Of all the fillers currently available, this one is the most resilient. Concrete is regarded as the best and most dependable building material when placed atop crushed granite stone.
In line with GOST 8267-93, these raw materials are categorized by brands separately from cement.
- M 200 – the weakest crushed stone;
- M 300/400/600 – weak;
- M 800/1000 – durable;
- M 1200/1400 – high -strength.
Furthermore, the standards consider the quantity of weak grains present in the entire mass of granite:
- M 200/300 – such raw materials contain up to 15% weak particles;
- M 400/600/800 – the mass fraction of weak grains does not exceed 10%;
- M 1000/1200/1400 – no more than 5% of weak rock.
Crushed stone of grade M 1200/1400 is advised for the preparation of high-strength concrete (for the construction of foundations and supporting structures) with a minimum strength of M 400.
Density and weight
Prior to anything else, it is imperative to define terms like "density of granite crushed stone," as many inexperienced builders have the wrong idea about them.
It is important to keep in mind that granite has an average density of 2600 kg/m^2. The average bulk density of granite is one such parameter, though. They calculate the weight of 1 m 3 of crushed stone in its "natural" state—that is, accounting for the spaces between the grains—using this indicator. This weight is directly correlated with the average bulk density and is referred to as volumetric. The bulk density parameter will be lower with higher crushed stone fractions. A smaller amount of cement will be needed to prepare concrete if this indicator is small.
The average density is typically calculated in a lab setting. The granite grain size directly affects its indicators. For instance, the following bulk density indicators apply to crushed stone M 1000:
- 1370-1400 kg / m 3 , if the crushed stone fraction is from 20 to 40 mm;
- 1380-1400 kg / m 3 , if grain sizes from 40 to 70 mm are used;
- 1400 kg/m3, provided that crushed stone with a fraction of 70 to 250 mm is used.
Understanding the granite’s specific gravity is also essential for determining the volume of raw materials needed.
Calculation of the specific gravity of granite
The size, weight, and sawing of the stone block—which is acquired during the processing of granite rock—all affect the weight of crushed granite. Standard stones range in thickness from 20 to 30 mm on average. You can calculate the weight of the products more precisely if you consider the stone’s dimensions and average specific gravity (2700–3000 kg/m³).
For instance, we just need to multiply these numbers (2.5 * 1.8 * 0.02) if we have a stone that is 2500 x 1800 x 20 mm. The weight of granite is calculated by multiplying the resultant number of 0.09 by the average specific gravity of 2.9, or 261 kg.
Flakiness
A percentage indicator of needle- and plate-shaped grains is a property like flakiness. The truth is that flat stones lower their quality indicators and dramatically increase the consumption of raw materials. Conversely, cuboid and needle-shaped stones are regarded as the best.
Crushed stone with a higher grade will have fewer "undesirable inclusions." GOST 8267-93 regulates this parameter as well. Based on this standard, gravel is categorized based on how flaky it is:
- cuboid (mass fraction of plate-shaped and needle grains does not exceed 15%);
- improved (with a mass fraction from 15 to 25%);
- normal (if the crushed stone contains from 25 to 50% flat grains).
Practical! The lowest quality gravel is regarded as being flat.
Furthermore, crushed granite stone can withstand temperatures as low as F 300.
The certificate attesting to the fact that the material’s norm for radioactive components is not exceeded must be taken into consideration when selecting this raw material. Since radium, thorium, and potassium are naturally present in granite rocks, the raw material needs to be properly tested before being sold.
As we discussed earlier, a lot of indicators rely on the percentage of the material. Now, let’s look at the standards that apply to granite size.
Crushed stone fractions
The fractions of crushed granite stone are categorized as follows:
Up to 5 mm in size of crushed stone. The majority of experts do not view granite chips (screenings) as a complete raw material. This type of material is used for patios in suburban areas, sports fields backfilling, and decorative finishing. In order to create a material that resembles "washed concrete" and to create surfaces lined with real stone, screenings are also added to cement-sand mortar. There is a lot of dust on screens. equates to M1000–1400 crushed stone grade.
Up to 10 mm in size of crushed stone. A relatively small fraction of the available material is dust-free. used to prepare concrete for use in building roads, bridges, and foundations as well as to make products like paving slabs and granite curbs. equates to M800–1200 crushed stone grade.
Up to 20 mm in size of crushed stone. The most widely used material, appropriate for airfield surfaces, bridge construction, and cladding as well as monolithic foundation construction. equates to M1400–1600 crushed stone grade.
Up to 40 mm in size of crushed stone. Crushed granite with a medium fraction is appropriate for building roads, foundations, and reinforced concrete structures. when adding filler to a cement-sand mixture with a 5–20 MPa strength. appropriate for building sites that will house heavy machinery. There is not more than 0.35% dust content. Matches M1000 grade crushed stone.
Up to 60 mm in size of crushed stone. Typically utilized in the building of railroad and tram tracks. Seldom utilized in privately constructed buildings. The amount of dust is not more than 0.25%. equates to M1000–1200 crushed stone grade.
Up to 70 mm in size of crushed stone. utilized in the building of substantial, large-scale structures. contained within 0.68% of dust. equates to M1000–1200 crushed stone grade.
Up to 300 mm in size of crushed stone. Concrete is almost never prepared using crushed stone. Large stones like these can be used to finish artificial reservoirs, swimming pools, fences, and many other things. corresponds to crushed stone grades M1000–1200.
The application of such material is greatly increased if the granite has been heat treated.
Granite crushed stone has special qualities that make it perfect for a variety of applications. It is a durable and adaptable material that is frequently used in landscaping and construction. This material aids in better soil drainage during sowing, reduces erosion, and creates a stable foundation for plant growth. You can use crushed granite stone more wisely in your projects, assuring both visual appeal and practical advantages, if you know how it interacts with plants and soil.
Features of porcelain stoneware
The process of semi-dry pressing and subsequent firing yields porcelain stoneware. Finishing work is the most common application for this material. You can realize any design idea because of this raw material’s aesthetic qualities and color variety. For instance, using porcelain stoneware to clad a staircase will look stunning. It is also frequently employed:
- For external and internal finishing of floors and walls.
- As a floor covering in high-traffic areas (shopping malls, metro, stores, etc.).
- For cladding building facades with colored tiles.
- For internal cladding of industrial premises. Porcelain stoneware is characterized by increased resistance to aggressive chemicals and heat resistance.
The specifications of the raw material also play a role in the price of crushed stone.
Because of its strength and adaptability, crushed granite stone is a common material used in construction. Fine granite rock that has been uniformly crushed into tiny pieces is used to make it. This makes it perfect for a wide range of uses, such as landscaping and road construction. It is a dependable material for any project because of its strength and ability to withstand weathering, which guarantee that it keeps its integrity over time.
The choice of crushed stone can affect the outcome when it comes to sowing. As a base layer, crushed granite stone improves drainage and offers a sturdy base for planting beds. Because of its angular shape, the stones are kept together and less likely to shift or settle. For your outdoor spaces to remain structurally sound and visually appealing, this stability is essential.
All things considered, crushed granite stone provides a combination of strength, toughness, and visual appeal. Selecting the appropriate kind of crushed stone can be crucial, regardless of the scale of the project—from a straightforward garden makeover to a major construction undertaking. Because of its qualities, which guarantee that it functions well in a variety of settings and endures over time, it is a popular choice.
