Technology of stabilisation and solidification of contaminated mercury chlor-alkali waste with sulfur microcements

This document describes a cement-based stabilisation and solidification technology developed to treat soils and industrial wastes contaminated with mercury from chlor-alkali processes. It outlines a sequential methodology that begins with analysing the chemical forms and quantities of mercury present, followed by detailed characterisation of the waste matrix and its physical properties. The process then selects suitable microcement materials, admixtures, and complementary aggregates to achieve a durable final material. The document explains formulation design, particle size considerations, mixing order, and curing conditions that promote chemical stabilisation through cement hydration reactions.
