Sulphur concrete (SC) is a material in which modified sulphur is used as the sole binder. It holds a lot of potential for application in products, designed for chemically difficult environments, such as frequently occur in agriculture. Two recent studies by Hellers and Thylén and by Ekblad prove the feasibility of the material. In the first, the fast-binding material was unreinforced and subjected to a combined attack from organic acids and high-pressure washing. In the second study, the material was prestressed and tested for mechanical capacity in bending and shear. Also, the bonding capacity of the prestressing strand to the surrounding material was tested with satisfactory results. Prestressed slats have now been tested over six months for creep and in practice under fattening pigs, including observations of deterioration, without regard to the possible chemical mechanisms involved. The creep seems to occur mainly within the first month. Indications of corrosion in practical tests confirm the visual impression that the material is not perfect, showing flaws and longitudinal cracks due to insufficient compaction in the casting process. In order to improve that process it has recently been concluded that the true thermoplastic nature of SC must be accounted for in the solidification phase. By computer modelling it is now possible to analyse the progress of the solidification front and the possibility of keeping paths open for a compensating binder flow which can fill out the contraction volume of the binder in the transition from the liquid to the solid stage. Probably, vibration energy must also be added to the process in order to obtain a fully compacted and uncracked product. The further practical implementation of a refined casting process remains to be realized within the next year, 1992–93.
