Volumetric and specific weight of concrete in 1 m³: concrete weight by grade

Below are average values for the weight of concrete when crushed stone, sand and cement are used.

A brief table of the specific weight of concrete.

The weight of 1 m³ of concrete can vary from 1.8 tonnes to 2.5 tonnes.

Weight of M100 concrete ~ 2.494 tonnes

Weight of M200 concrete ~ 2.432 tonnes

Weight of M250 concrete ~ 2.348 tonnes

Weight of M300 concrete ~ 2.389 tonnes

Weight of M350 concrete ~ 2.502 tonnes

Weight of M400 concrete ~ 2.376 tonnes

Weight of M500 concrete ~ 2.298 tonnes

Concrete is the main component of any construction work, whether it is ordinary repair work or the construction of pits and structures. It initially has high strength, but its characteristics can be improved by using additives.

In construction, the first thing to calculate is how much concrete weighs (the weight of a cube of concrete), because this characteristic determines the specifics of its use and application. The weight of concrete directly depends on the components added as fillers. These may include crushed stone, expanded clay, gravel and many other materials. The volume of water used in mixing is also taken into account. Based on these characteristics, concrete is divided into four types: light and heavy, extra-light and extra-heavy.

Extra-light concrete — concrete with small and medium-sized air cells (up to 1-1.5 mm) in large quantities (up to 85%). Such concrete is mainly used for thermal insulation of premises. The weight of extra-light concrete per cubic metre does not exceed 500 kg.

Lightweight concrete — concrete with a porous structure or with lightweight aggregates such as expanded clay, with the mandatory addition of about 600 kg of sand. This type of concrete is used in the form of ready-made building blocks. The weight of lightweight concrete per cubic metre is from 500 to 1800 kg.

Heavy concrete — classic concrete with the addition of heavy and coarse aggregates such as gravel or crushed stone, which make up the main mass of the concrete. Approximate proportion: gravel or crushed stone — 1150-1300 kg, cement — 250-450 kg, sand — 600-750 kg, water — about 150-200 litres. This type of concrete has a wide range of applications. The weight of heavy concrete per cubic metre is from 1800 to 2500 kg.

Extra-heavy concrete — concrete containing various types of metal scrap, barite, hematite and magnetite, which determine its main mass. It is mainly used to protect personnel from radioactive radiation. The weight of extra-heavy concrete per cubic metre is from 2500 to 3000 kg.

Concrete weight depending on its grade and admixtures

It is important to take into account that tables do not make it possible to calculate the weight of a cubic metre of concrete simply by taking the weights of all components separately, adding them together and obtaining a value for the whole product. The weight of 1 m³ of concrete depends on various factors, such as the quality of mixing, the amount of water, the presence of voids and the size of the granules.
