To carry out various construction works, even on a small scale, it is necessary to first calculate the amount of required material. Calculating piece building materials is not difficult. It’s 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 are there in a cube of rubble? Useless at first glance, knowledge will be useful to everyone who begins 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 have to pay for it for sure.
Factors affecting the determination of crushed stone mass
To calculate how many tons are in a cube of crushed stone, the following criteria should be considered:
- the type of rock of the material from which the material is made;
- fraction size;
- flakiness;
- moisture absorption.
We will consider these factors in the article.
Types of rubble
You probably noticed that gravel is different. You should not delve into geology, because you can make gravel 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 crushed stone:
- granite;
- basaltic;
- 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. Granite material is also used for decorative purposes.
Crushed basalt is extracted from basalt rock. According to its characteristics, this material is a competitor to granite stone. Crushed basalt has high thermal conductivity, density, strength, frost resistance. It is used as a filler in the manufacture of heavy concrete, in the construction of road surfaces, for the decoration of buildings.
Crushed gravel is produced from loose sedimentary rock. This material has the shape of rounded pebbles. It is used in road construction. Small fractions are used as decorative material. Gravel has quite high quality indicators and low cost.
Limestone crushed stone is a unique building material, which is extracted from limestone - sedimentary rock. It is highly resistant to temperature extremes, as well as impact resistance. It is an environmentally friendly material. Crushed limestone is used in road construction and lime production. It is also used as a facing stone.
Crushed stone size
All types of crushed stone are divided into fractions that determine its size. Imagine a cube with a face length of 10 mm or a ball with the same diameter. And now - a larger ball and cube, for example, 20 mm. Take a bunch of one and the other, and then mix. As a result, get the size (fraction) of 10-20.
The most demanded by consumers is granite crushed stone of size 5-20. This material is used for the 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 in the cube of gravel fraction 5-20. We will not load you with calculations, but give the average volumetric weight. For such a fraction of crushed stone, it is 1.38 t / m 3 .
In the initial stages of the construction of various objects, a larger stone is used. It can be granite crushed stone in the size of 20-40. It is used to fill the entrances to construction sites, foundations. In order to fully provide the building object with this material, it is necessary to know how many tons are in the cube of crushed stone of fraction 20-40. The volumetric weight of such a stone is 1.41 t / m 3 .
For filling roads and sites requiring heavy loads, crushed stone of size 40-70 is used. Especially often it is used to equip construction sites on fluid soils. How many tons in a cube of crushed stone of fraction 40-70 is easy to calculate. However, do not waste time calculating. Granite crushed stone has an average volumetric weight of 1.47 t / m 3 .
In railway, industrial, housing construction, in the manufacture of massive reinforced concrete structures, crushed stone of size 25-60 is used. Ordinary users who use this material for various buildings want to know how many tons are in the crushed stone cube fraction 25-60. We answer: in one cubic meter 1.38 tons of stone of this size.
Flattery
Flakiness (form) is one of the important parameters taken into account when determining how many tons are in a cube of crushed stone. The density of the level of filling of the volume depends on what form the material has - lamellar, needle or cuboid. In order to avoid overspending of basic materials and for denser filling, it is necessary to buy crushed stone with a flaskiness of no more than 15%.
Water saturation
Water saturation is a criterion that affects the weight of crushed stone. The more garbage, the higher this indicator. The average percentage, depending on the type of gravel, reaches 10%. The water saturation of the trash material reaches 100% or more. No need to purchase rubble that looks like garbage: dirty or with a lot of sand. In addition to being heavier, such material can be produced from construction waste. It costs less.
Specific Gravity (HC)
All the above factors, both as a whole and individually, affect the determination of how many tons are in a cube of crushed stone. These indicators vary slightly in different geographical 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. Reversing is also easy. If you have the amount in tons, divide it by 1.4 - and get the cubic capacity as a result.
