摘要:
A method of overlaying sulphur concrete is adapted for use in placing sulphur concrete against or over an existing solid surface such as the exterior surface of a wall, floor, or column base. The existing surface, which typically is a portland cement concrete surface, is prepared by first applying a layer of a bituminous material containing a bitumen which liquifies at temperatures corresponding to the pour temperatures of the sulphur concrete. The sulphur concrete is poured against or over the bitumen-containing surface so that the bitumen therein melts to form a liquid slip plane. The shrinkage of the sulphur concrete which occurs during its temperature-reduction setting occurs without producing cracks because of the relative slippage permitted between the existing wall surface and the sulphur concrete.
