Mechanical characteristics equivalent to concrete

By combining modified sulphur with sand, gravel and filler similar material qualities are obtained as with cement concrete. Tested in accordance with: NEN-EN 12390-3, NEN-EN 12390-6, NEN-EN 1992-1-1  

Convenient crushing strength for main sewerage

The Thio Material shaft units wholly answer to strength class 60. The unreinforced cover slab meets the requirement of 300 kN crushing strength according to PTV 823. The unarmoured tubes conform to strength class 160 in accordance with PTV 823 (vitrified clay pipes strength class 160  – concrete: strength class 250).


Acid proof (to pH 0)

The resistance of Thio Material against biogenic sulphide corrosion was tested in accordance with the TAP-test (University of Ghent – Laboratory Magnel – Prof. Dr. Ir. N. De Belie). During this test, part of a disk is immersed and turned round Lees meer


Resistant to bases (to pH 12)

As per the acid resistance tests on corrosion, disks of Thio Material were tested as to their resistance against bases during TAP-tests. The tests were made in the following mediums: sodium hydroxide  (NaOH;pH 12) and Sodium carbonate (Na2CO3 ;soda pH Lees meer

Resistant to sulphates

Cement concrete can also be affected by sulphate-containing sewage  water and groundwater. This comparatively light attack happens relatively slowly. Sulphates react to components (C3A) of cement stone, during which process crystals are formed. The consequence of this is an expansion Lees meer

Abrasion resistance

Flowing water that possibly contains abrasive material (sand, stones, …) can weigh heavily on the wall surface of the used product. Abrasion resistance can be measured using  the Darmstadt testing method. According to the measures, given by DIN EN 295, Lees meer

Watertight at 1 bar

On account of its dense structure and its hydrophobic behaviour, Thio Material is quasi- impermeable. Consequently the material is also characterized by a very low water-absorption capacity, which is between 0.2 and 0.5%. This is very low if compared with Lees meer

100% recyclable – ‘Cradle to cradle’

As it can be re-melted Thio Material is 100% recyclable for similar applications. Concrete and vitrified clay pipes are almost always reused as a foundation material in road construction.  Research centre: De Bonte (BE)    

Reduced CO2 footprint

Despite the fact that during the production process Thio Material has to be heated up to 135°C before it can be handled, the process generally consumes much less energy than classical concrete production. During the production of Portland cement the Lees meer
