Technology and properties of high-strength sulfur concrete modified with organometallophosphate compounds

Abstract

Today, using waste from heat and power plants for sulfur concrete production is one of the most efficient ways to address critical challenges in the construction industry: production of high-strength, extra dense, and durable concretes, lower concrete energy-output ratio, and a lower consumption of cement. The paper describes the process of making high-strength sulfur concrete using ash and slag waste from combined heat and power plants, which is modified with calcium glycerylphosphate with high physical mechanical properties. It is found that high strength properties and resistance to aggressive environments and water are associated with the chemical interaction between the components and the formation of polysulfides, probably, with the cross-linked structure. The designed material can be used to make tiles, floors, curb stones, to synthetize aggressive materials, and in the heat power industry.
