Abstract	Studies of alkali-expansivity of Nova Scotia rock types included extensive length change tests of mortar bars and concrete prisms, and also rock cylinders immersed in alkali solution. The effects of such variables as alkali content, type of alkali, temperature, wet and dry cycling, anisotropy, optimum proportion of rock type, and the influence of pozzolan and fly ash were studied. Results obtained were correlated with petrographic studies so that potentially expansive rock types in the province may be recognized. Preventive measures applicable to field use were determined from analyses of expansion data.
