Mineral powders
Mineral powders MP-1 and MP-2 are the basis of modern road construction and asphalt concrete production.
Mineral powders are produced as a result of repeated grinding, grinding and drying of solid carbonate-containing mineral rocks.
The use of mineral powders as raw materials for asphalt concrete allows you to achieve maximum adhesion (level of adhesion) of the road surface, increases the elasticity, increases the strength and wear resistance of the material, reduces water absorption, increases the ability of asphalt concrete to deform, as well as frost resistance, significantly increasing the service life of the resulting roadbed.
In addition, mineral powders are used in construction works of compacted (concrete) castings as a filler that improves the physical and chemical properties of solutions, increases elasticity and density.
Due to the fact that at the moment there are still 2 state standards regulating the production of mineral powders, our customers often have a lot of questions and confusion in the terminology and differences in the brands of mineral powders.
We will help you to understand this issue!
There is GOST R 52129-2003 Mineral powder for asphalt concrete and organomineral mixtures. It is still used (most often when developing technical specifications for small local roads).
According to this GOST
MP-1 is made as a result of repeated grinding of carbonate-containing mineral rocks (marble, dolomite, limestone) to a fraction of 300 micrometers.
MP-2 is obtained by processing non-carbonate rocks, industrial waste.
MP-1 and MP-2 application areas:
|
Stamp mineral powder |
Type of mineral powder | Scope of application |
| MP-1 | mineral powder MP-1 from carbonate rocks, sometimes activated by surfactants and not activated |
Added to: asphalt concrete mixes made according to GOST 9128: asphalt-concrete crushed stone-mastic mixtures manufactured according to GOST 31015 organomineral mixtures according to GOST 30492 |
| MP-2 | mineral powder from non-carbonate rocks and solid industrial waste |
asphaltconcrete mixes according to GOST 9128 grades I and II organomineral mixtures according to GOST 30491 |
| Mineral powder from industrial waste powder |
asphalt concrete mixes according to GOST 9128 mark III organomineral mixtures according to GOST 30491 |
That is, if the Technical specification of the Customer prescribed mineral powder GOST R 52129-2003-then we can offer you MP-1 activated surfactant acids, MP-1 non-activated surfactant acids. We do not produce MP-2, because in fact MP-2 is a low-quality product of processing slags and other industrial waste.
However, most often in recent years, GOST32761-2014 is used for public automobile roads.Mineral powder. Technical requirements. It is already used everywhere in the regulation of the construction of roads of federal and regional significance.
In this GOST, low-quality powder from slag and recycled rocks is placed in a separate category-MP-3.
MP-1 is an activated mineral powder: Material obtained from carbonate rocks with the addition of activating substances.
MP-2 is an inactive mineral powder: The material obtained by grinding carbonate rocks, without the addition of activating substances.
For convenience, you can use the data from this table:
|
Brand of mineral powder |
Type of mineral powder |
Scope of application |
|
MP-1 |
Activated from carbonate rocks |
Any asphalt concrete and organomineral mixtures |
|
MP-2 |
Inactivated from carbonate rocks |
|
|
MP-3 |
From non-carbonate rocks and solid industrial waste |
Any asphalt-concrete and organomineral mixes, except for asphalt-concrete mixes of the I grade and crushed stone-mastic mixes |
|
Powder waste of industrial production |
Any asphalt-concrete and organomineral mixes, except for asphalt-concrete mixes of grades I and II and crushed stone-mastic mixes |
The mineral powder plant "Basis" produces mineral powders from marble - samo1, a strong carbonate-containing rock, unactivated and activated with surfactants to further improve the quality of the material.
