About abrasive AMT ®


Source of raw materials

The raw material for AMT ® is produced in melt furnaces in a semi-reduction atmosphere and at a temperature of about 1500°C. Granulated glass is formed by rapid cooling from water and contraction.


The production of AMT ® is done by drying, crushing and sorting the melt on a production line located on the premises of the manufacturer in Paskov – Oprechtice. The industrial area where the production line is located includes warehouses and can be found about 500 meters from the Ostrava – Frýdek-Místek highway (5 km from Ostrava) and is connected to railway siding (CD).


The composition of the abrasive material AMT ® makes it friendly to the environment. It meets the strictest environmental criteria and is thus able to replace the most widely used abrasive now – quartz sand. According to many independent tests that we conducted, AMT ® is inert, i.e. it does not react with other substances and thus cannot affect the surroundings.
When a dry substance or admixture is added to concrete (mortar), this inert material binds to the solid phase and so cannot harm the environment in any manner of use.
On the other hand, increased attention should be given to the treatment of residues (waste) after blasting work. Inasmuch as abrasive material becomes contaminated with coating material during such work, often containing a high proportion of heavy metals (Pb, As), this material must be handled accordingly in this case. Abrasive material also becomes contaminated with organic, carcinogenic or toxic substances, which requires adequate measures to be taken in accordance with the Waste Act, No.185/2001 Coll. There is absolutely no need to increase fire safety measures due to the nature of this abrasive material.

When using abrasive material for blasting, increased health and safety risks must be taken into consideration. Parts of the face can be hit by a stream of blasted or ricocheted material and one of the responsibilities of personnel is to have the prescribed personal protective equipment on. This means complete protective clothing according to the type of work and type of polluted residue left over after blasting, as well as firm work boots and gloves, and a protective face shield with an external and regulated supply of fresh air for breathing.

When using an abrasive material for blasting toxic layers, measures must be taken to ensure there are no risks to the health of workers or to the environment from contamination, and to keep all tools from being contaminated from possible fly ash or other residues. Only machinery approved for the purpose of this work should be used and the operational documentation processed (Operation Rules) for your own facility, submitted for approval by the local health authority. Technical supervision in the workplace (facility) is necessary to monitor compliance with the principles of safety and the use of machinery (according to the manufacturer’s documentation). The use of required protective gear and compliance with procedures must also be checked (Act No. 155/2000 Coll., and 258/2000 Coll.).
