Water-Resistant Gypsum Binding Agents and Concretes Based Thereof as Promising Materials for Building Green
[摘要] For gypsum-based cementing materials, environmental advantages are highlighted over Portland cement, and major method for increasing their water resistance are described. By the example of gypsum-lime slag binders, a successful application of water-resistant gypsums is demonstrated in the severe climatic conditions of the Ural region. Phase composition analysis results are presented for gypsum-lime slag stone-like material after years of operation as part of the concrete walls of enclosures. It is found that durability of the material can be explained by the formation of stable compounds: calcium sulfate dihydrate, calcium carbonates and calcium hydrosilicates of the type CSH(B).
