USE OF SULPHUR INFILTRATED PRE-CAST SLABS ON CROSS-DRAINAGE WORKS ON ROADS

Tests are described which reveal the unsuitability of local Mizoram State rocks for use as concrete aggregate. To avoid importing aggregate from over 200km away, alternative materials in particular sulphur infiltrated precast slabs are considered. The theory behind enhancement of strength by sulphur infiltration is outlined. The advantages of sulphur impregnation are listed including its low cost and abundant availability and melting characteristics. One disadvantage is described - low fire rating. Methods of sulphur infiltration are discussed including infiltration at atmospheric pressure and under vacuum followed by pressure treatment. Details are listed of the improvement in compressive strength, durability, impermeability, resistance to aggressive environments and resistance to freezing and thawing caused by sulphur impregnation. Design details are tabulated and costings provided. It is concluded that sulphur infiltration provides a useful alternative where there are no hard rocks, it is particularly suitable to areas with cyclic variations in temperature and easier to carry out than the addition of polymers.
