QUICK LIME-GYPSUM INTERACTIONS IN STABILIZED SOIL BASES FOR CONCRETE HIGHWAYS

This paper presents comments on the nature of sulphate attack in lime stabilized soils. A portion of the paper includes the presentation of data and conclusions obtained from an actual construction project that experienced detrimental sub-base heaving due to sulphate attack. It is concluded that lime, type 1 portland cement, or class c fly ash stabilization of high gypsum bearing soils would at best produce poor results because of the possibility of expansion due to the formation of ettringite. Several other reactions are considered which may contribute to expansion in construction projects when quick lime and/or class c fly ash are used for the stabilizing agent and a free source of gypsum is available.
