Abstract: The inclusion of fibre elements in a sulphur/mineral aggregate composition, for example, a sulphur concrete or mortar, improves the fracture toughness of the composition and retards crack propagation.

Abstract: Sulphur compositions, particularly sulphur concretes, mortars and coatings, comprising a sulphur component and a particulate mineral aggregate in which the aggregate is bonded together in a matrix of the sulphur component having a plurality of fine entrained cells, particularly substantially spherical gas cells, uniformly dispersed throughout the matrix, and displaying improved durability under cyclical freezing and thawing.

Abstract: Shaped sulphur concrete articles are produced from a moldable composition of a mineral aggregate, mineral binding agent, a sulphur component, such as elemental sulphur, and a liquid vehicle such as water; the mixture is compacted and formed into a shaped body at an elevated compacting pressure, dried to volatilize the liquid vehicle and heated to melt the sulphur, whereafter it is cooled to solidify the sulphur whereby the mineral materials are bonded into a matrix with the sulphur. The articles can be produced without shrinkage with predetermined dimensions and exhibit good compression strength and durability.

Abstract: Sulphur concretes and mortars are provided which display improved ductility and in which water-resistance is provided in otherwise water-disintegratable compositions due to the presence of swelling clay in the mineral aggregate. The improved properties are obtained by the use of petroleum additives such as crude oil and polyol additives such as glycerol.

Abstract: A small amount of an organosiloxane polymer stabilizes an emulsion of sulphur and a bituminous material in which the bituminous material is a continuous phase and the sulphur is a dispersed phase; the stabilized emulsion serves as a binder for mineral aggregates in the manufacture of paving mixtures.
