โœฆ Synopsis

Sulphur-infiltrated concretes have been treated with aqueous solutions of acid, base and salt. From the ESCA decomposition products were identified and using ultraviolet spectroscopy it was possible to identify thionates and polysulphides as intermediates. Thiosulphates were also found in the leachate but the final product was a mixture of calcium sulphate, sulphite and elemental sulphur. Decomposition in salt solutions is significantly slower than in water.
