For various construction works, even on a small scale, it is necessary to first calculate the amount of material required. It will not be difficult to calculate piece building materials. It is a little more difficult to find out the required amount of crushed stone, sand, clay, cement. The calculation of such materials should be carried out taking into account their features. So, how many tons in a cube of crushed stone? Useless at first glance, knowledge will be useful to everyone who starts their own construction. And even if you plan to use hired workers, you still have to control the consumption of sand and gravel, because you will definitely have to pay for it.
Factors affecting the determination of the mass of crushed stone
To calculate how many tons of crushed stone in a cube, the following criteria should be taken into account:
- type of rock from which the material is made;
- fraction size;
- flakiness;
- moisture absorption.
We will consider these factors in the article.
Types of crushed stone
You probablynoticed that the gravel is different. You should not delve into geology, because crushed stone can be made from any stone by passing it through a crusher. Each breed has its own density, which, in turn, affects the specific gravity. There are several types of gravel:
- granite;
- bas alt;
- gravel;
- limestone.
The material that comes first on the list is mined in quarries from rocks of granite rocks. It is made by grinding fragments obtained after blasting. Granite crushed stone possesses durability and natural color scale. It is the most common and is used for the construction of various structures, foundations, roads. Also, granite material is used for decorative purposes.
Bas alt crushed stone is mined from bas alt rock. According to its characteristics, this material is a competitor to granite stone. Bas alt crushed stone has high thermal conductivity, density, strength, frost resistance. Used as an aggregate in the manufacture of heavy concrete, in the construction of road surfaces, for finishing buildings.
Crushed gravel is produced from loose sedimentary rock. This material has the form of rounded pebbles. Used in road construction. Small fractions are used as a decorative material. Gravel has a fairly high quality and low cost.
Crushed limestone is a unique building material that is mined from limestone, a sedimentary rock. He possesseshigh resistance to temperature extremes, as well as impact resistance. This is an environmentally friendly material. Limestone crushed stone is used in road construction, lime production. It is also used as a facing stone.
Size of rubble
All types of crushed stone are divided into fractions that determine its size. Imagine a cube with a side length of 10 mm or a ball with the same diameter. And now - a ball and a larger cube, for example, 20 mm. Take a bunch of one and the other, and then mix it up. As a result, get the size (fraction) 10-20.
The most demanded by consumers is crushed granite in size 5-20. This material is used for manual production of garden paths, paving slabs, parking lots, as well as in the production of various reinforced concrete products. In this regard, summer residents and owners of individual houses are interested in how many tons of crushed stone of fraction 5-20 are in a cube. We will not load you with calculations, but we will give the average indicators of volumetric weight. For such a fraction of crushed stone, it is 1.38 t/m3.
At the initial stages of construction of various objects, a larger stone is used. It can be granite crushed stone 20-40 in size. It is used for backfilling entrances to construction sites, foundations. In order to fully provide a building object with this material, it is necessary to know how many tons of crushed stone of fraction 20-40 are in a cube. The volumetric weight of such a stone is 1.41 t/m3.
For backfilling roads and sites requiring heavy loads,crushed stone 40-70 in size is used. Especially often it is used for arranging construction sites on fluid soils. It is not difficult to calculate how many tons of crushed stone of fraction 40-70 are in a cube. However, do not waste time on calculations. Granite crushed stone has an average volumetric weight of 1.47 t/m3.
Crushed stone 25-60 in size is used in railway, industrial, housing construction, in the manufacture of massive reinforced concrete structures. Ordinary users who use this material for various buildings want to know how many tons of crushed stone of fraction 25-60 are in a cube. We answer: in one cubic meter there are 1.38 tons of stone of this size.
Flakiness
Flakiness (shape) is one of the important parameters taken into account when determining how many tons of crushed stone are in a cube. The density of the filling level of the volume depends on what shape the material has - lamellar, needle-shaped or cuboid. In order to avoid overspending of basic materials and for denser filling, it is necessary to buy crushed stone with a flakiness of no more than 15%.
Water saturation
Water saturation is a criterion that affects the mass of crushed stone. The more garbage, the higher this indicator. The average percentage, depending on the type of crushed stone, reaches 10%. Water saturation of littered material reaches 100% or more. No need to purchase gravel that looks like garbage: dirty or with a lot of sand. In addition to being heavier, such material can bemade from construction waste. It costs less.
Specific Gravity (SG)
All of the above factors, both in general and individually, affect the determination of how many tons of crushed stone are in a cube. These figures vary slightly in different geographic and weather conditions. If you want to independently calculate the volumetric weight of crushed stone, multiply the cubes by a factor of 1.4 and get tons. It's also easy to translate the other way around. If you have a quantity in tons, divide it by 1, 4 - and get the cubic capacity as a result.
