Title: The Use of Sulfur Concrete for Hydraulic Concrete Overlays
Author(s): Alan H. Vroom
Publication: Special Publication
Appears on pages(s): 87-98
Keywords: Acid resistance; concretes; permeability; resurfacing; strength
Abstract:Sulfur concrete (SC) has been used successfully as an overlay to protect hydraulic concrete from attack in highly corrosive environments The SC dealt with in this paper is based on Canadian technology which uses a sulfur cement composed principally of thermodynamically stable, microcrystalline sulfur. Methods for the production and placement of this SC are discussed, together with several case histories of its use as an overlay on hydraulic concrete. Field experience has shown SC to be a durable, cost-effective overlay with many of the attractive physical characteristics of polymer concretes, such as high resistance to corrosion and abrasion, impermeability and high physical strength.. Being a hot mix, produced in a modified asphalt plant, it must be placed as an overlay in a thickness of at least 3 in.(7.5 cm) unless the substrate has been warmed. SC overlays can be placed with vibrating screeds and with slightly modified asphalt and concrete paving machines
