# How to calculate how many tons in a cube of rubble

For various construction works,even on a small scale, you must first calculate the amount of material required. Counting piece building materials will not be very difficult. It is a bit harder to find out the required amount of gravel, sand, clay, cement. Calculation of such materials should be carried out taking into account their features. So how many tons are there in the cube of rubble? Useless at first glance, knowledge will be useful to all who begin their own construction. And even if you plan to use hired workers, you still have to control the consumption of sand and rubble, because you have to pay for it for sure you.

## Factors affecting the determination of the mass of crushed stone

To calculate how many tons in a cube of rubble, you should consider the following criteria:

- type of rock material from which the material is made;
- fraction size;
- flakiness;
- moisture absorption.

These factors we will consider in the article.

## Types of crushed stone

You, probably, paid attention, that rubblecan be different. In geology it is not necessary to delve, because from any stone you can make rubble, passing it through a crusher. Each breed has its own density, which, in turn, affects the specific gravity. There are several types of rubble:

- granite;
- basaltic;
- gravel;
- limestone.

The material that goes first in the list is minedin quarries from rocks of granite rocks. It is produced by grinding the debris obtained after blasting. Granite gravel has durability and natural color scale. It is the most common and is used for the construction of various structures, foundations, roads. Also, the material from granite is used for decorative purposes.

Basalt crushed stone is extracted from the rockbasalt. By its characteristics, this material is a competitor to granite stone. Basalt crushed stone has a high thermal conductivity, density, strength, frost resistance. Used as a filler in the manufacture of heavy concretes, for the construction of road surfaces, for finishing buildings.

Gravel crushed stone is produced from loose sedimentaryrock formation. This material has the shape of rounded pebbles. It is used in road construction. Small fractions are used in the form of decorative material. Gravel has high enough quality indicators and low cost.

Limestone crushed stone is uniquebuilding material, which is extracted from limestone - sedimentary rock. It has a high resistance to temperature changes, as well as impact resistance. It is environmentally friendly material. Used limestone crushed stone in the construction of roads, the production of lime. It is also used as a facing stone.

## Size of crushed stone

All types of rubble are divided into fractions,which determine its size. Imagine a cube with a face length of 10 mm or a ball with the same diameter. And now - a ball and a bigger cube, for example, 20 mm. Take a bunch of one and the other, and then mix. In the end, get a size (fraction) of 10-20.

The most popular consumers aregranite rubble with the size of 5-20. This material is used for the production of a hand-made garden path, paving tiles, parking lots, as well as in the manufacture of various reinforced concrete products. In this regard, summer residents and owners of individual houses are interested in how many tons of rubble in the cube of 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 / m3.

At the initial stages of construction of variousobjects use a larger stone. This can be a granite crushed stone with a size of 20-40. It is used to fill the approaches to construction sites, foundations. In order to fully ensure the building object with this material, it is necessary to know how many tons of rubble in the cube of fraction 20-40. The bulk weight of this stone is 1.41 t / m3.

For pouring roads and sites that require largeLoads, rubble with the size 40-70 is applied. Especially often it is used to equip construction sites on flowing soils. How many tons in a cube of rubble of fraction 40-70 - to count it is simple. However, do not waste time on calculations. Granite crushed stone has an average bulk density of 1.47 t / m3.

In railway, industrial, housingconstruction, in the manufacture of massive reinforced concrete structures crushed stone is used in the size of 25-60. Simple users who use this material for various buildings, want to know how many tons of crushed stone in the fraction 25-60. We answer: in one cubic meter, 1.38 tons of stone of this size.

## Fleshiness

Flakiness (form) is one of the important parameters,taken into account when determining how many tons of crushed stone in the cube. The density of the level of filling of the volume depends on the shape of the material - lamellar, acicular or cuboidal. In order to avoid overspending of basic materials and for denser filling, it is necessary to buy rubble with a flakiness of no more than 15%.

## Water saturation

Water saturation is a criterion that affectsmass of rubble. The more rubbish, the higher this figure. The average percentage, depending on the type of rubble, reaches 10%. The water content of the litter is 100% or more. Do not need to buy rubble, which looks like garbage: dirty or with a lot of sand. In addition to being heavier, such material can be produced from construction waste. It is cheaper.

## Specific weight (SW)

All of the above factors, both in general and in terms ofseparate, affect the determination of how many tons in the cube of rubble. These indicators vary slightly in different geographical and weather conditions. If you want to calculate the bulk weight of rubble yourself, multiply cubes by a factor of 1.4 and get tons. Conversely, conversely, it's easy too If you have a quantity in tons, divide it by 1.4 - and get the result in cubature.
