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. |
