Gypsum-Lime-Slag Binders and Concretes on their Basis: an Experimental Assessment of Durability
The history of creation of a gypsum-lime-slag binder as well as the industrial experience in production and application of wall products and structures on its basis is described. Theresults of on-site investigations of 10 buildings constructed of gypsum-lime-slag concretes in Sverdlovsk Oblast from 1960 up to 1980 that confirms the high weathering stability anddurability of the artificial stone on the basis of this type of gypsum binders are presented. The strength of gypsum-lime-slag concretes after the half- century operation in the form of wallstructures exceeds two times the handling strength and is 11-13 MPa.
