Original Abstract

This paper deals with the development of a new mortar, for cement-based inverse grouting, with an increased degree of chemical resistance. The aim of this work is to verify new mixtures optimized by suitable secondary raw materials. The studied parameters include the depth of corrosion of the test specimens when exposed to sulfuric acid solution and the sulphate resistance to the Na2SO4 solution is also studied. The results of this work show that it is possible to increase the chemical resistance by optimizing the grouting mortar mixture with suitable secondary raw materials. The optimized mixture for the new grout will be part of a comprehensive material system for the remediation of sewers or shafts.
