EFFECT OF MINERALOGICAL COMPOSITION OF FINES ON FROST SUSCEPTIBILITY OF SOILS

A 3-YEAR PROGRAM OF LABORATORY TESTING HAS LED TO SOME CORRELATIONS BETWEEN THE MINERALOGICAL COMPOSITION AND THE FROST SUSCEPTIBILITY OF SOILS. FREEZING TESTS PERFORMED ON ABOUT 400 ARTIFICIALLY BLENDED SPECIMENS WITH VARIOUS AMOUNTS AND DIFFERENT KINDS OF MINERAL FINES MIXED WITH A CLEAN SAND, A SILT, A LEAN CLAY AND A HEAVY CLAY INDICATE THAT (OF THE MINERALS STUDIED) MINERAL FINES OF RELATIVELY HIGH FROST-HEAVE-PRODUCING ABILITY ARE, IN INCREASING ORDER: MUSCOVITE (A MICA), CALCITE AND MAGNESITE (CARBONATES), IRON MONTMORILLONITE, ILLITE, KAOLINITE, NONTRONITE (AN IRON MONTMORILLONOID), AND ATTAPULGITE. THE TESTS ALSO DEMONSTRATE THE HEAVE-INHIBITING EFFECTS OF SODIUM MONTMORILLONITE AND PEAT FINES. FREEZING TESTS CONDUCTED ON 17 SELECTED SOILS APPROXIMATELY CONFIRM IN MOST PARTICULARS THE RESULTS OF THE TESTS ON ARTIFICIAL BLENDS. /AUTHOR/
