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).

Application area up to 80°C

Sulphur concrete was tested  for compressive and tensile strength as well as its dynamic E-module and creep (1 year). This within a range of temperatures between 20 an 80°C in order to check its performance in hot environmental temperatures and Read more

Acid proof (to pH 0)

The resistance of sulphur concrete 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 Read more

Extremely low permeability

With its dense structure and its hydrophobic nature Thio Material is nearly impervious and is characterized by a very low permeability. The water absorption fluctuates between 0.2 % and 0.5%, which is very low in comparison with cement concrete, which Read more

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 Read more

Resistance against repeated temperature cycles

A succession of significant temperature fluctuations can lead to an accelerated decrease of material performance.  Tests held during 150 day cycles between –20°C and 60°C combined with a relatively high degree of humidity, prove that Thio Material does not show Read more

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, Read more

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 Read more

A2 fire class

At WRF GENT (BE), tests on the fire-resistance sulphur concrete have been conducted.  Thio Material can be classified under fire class A2. From this test, it can be concluded that the behaviour of this material does not contribute to a Read more

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 Read more

Resistance against erosion

During  experimentation, the performance of Thio Material was tested in multiple ways. The  wearing resistance, tested in accordance with the wide wheel abrasion test (Capon), shows the same performance  when compared to cement concrete. Furthermore, big plates – ‘Ecopanels’ – Read more

Resistance against vibrations

At the test centre of SNCF (National Railway Company of France) dynamic tests were conducted during which the test piece, made Thio Material, was tested with a load varying between 10 and 126 kN during 3.106 cycles. After this test, there Read more
