Today, the use of cement powder in construction is in high demand. We are talking about both the use of pure building materials and a dry structural mixture that turns into a solution by adding water. For the construction process, it is very important to calculate the total mass of powder needed to fill the foundation. The main indicator in this case is considered to be specific (volume) weight or bulk density of the powder.
Density change for bulk powder
There are many factors of production and operation that affect how Cubes and kg of loose powder are combined with each other. Regardless of whether the building material is delivered in bags or delivered in bulk, its density characteristics are affected by the following factors::
- date of manufacture;
- technological features of the production process;
- type and brand of the product;
- conditions of storage and transportation, as well as use of materials.
Important! Today, the values of the volume weight of cement are tabular. The following are the most popular combinations (name-dense value), as well as possible situations in which these indicators change up/down.
| Name or brand name of the warehouse | Dense value (kg / m3 ) |
|---|---|
| M 100 | 900 |
| M 150 | 900 |
| M 200 | 900 |
| M 300 | 1100 |
| M 400 | 1100 |
| M 500 | 1100 |
| Composition with sand | 1700 |
| Composition with perlite | 1000-1400 |
| Composition with slag | 1000-1400 |
It should be noted that the specific gravity of cement 500 is 1,100 kilograms per cubic meter, but this value will change during transportation. During transportation, the cement 500 is saturated with air, which leads to a decrease in density. After delivery and gradual tamping, the volume weight of cement 500 is normalized. The reverse situation may occur when the powder is over-wet, in which case the value will increase to the limit values.
