Development of Tailings Based Polymer-Modified Waterproof Mortar

Abstract:

A large amount of tailings were produced with the development of mineral resources which cause great danger to the natural environment. An environment friendly waterproof mortar was developed by mixing polystyrene-(2-hydroxyethyl methacrylate) (PS-HEMA), iron tailings, steel slag, additives and cement. The polymer-cement ratio, cement-sand ratio and defoamer-cement ratio on the performance of the mortar were investigated. The factor design was used to determine the optimal process conditions: polymer-cement ratio, 12%; cement-sand ratio, 1:2.5; defoamer-cement ratio, 0.8%; water reducing agent (based on the cement weight), 0.5%. The product conforms to JC/T984-2005 (China professional standard: Polymer cement waterproof mortar). The radioactivity conforms to GB/6566-2010 (China mandatory standard: Building materials radionuclide limited). The applicable temperature of mortar was above zero through discussion.
