EVALUATION OF SOUTH DAKOTA DEICER NO. 2 AND CALCIUM MAGNESIUM ACETATE BY SHEAR TESTING

A laboratory study was performed in which the relative effectiveness of deicing materials as agents for the reduction of bond strength of ice to portland cement concrete (PCC) was determined. The materials of primary interest were South Dakota Deicer No. 2 (SD2) and calcium magnesium acetate (CMA). The materials were evaluated using interfacial shear strength tests of ice on PCC treated with aqueous solutions of the salts. Sodium and calcium chlorides were also included in the study for comparison. Results indicate that SD2 and CMA are significantly more effective in reducing the ice-pavement bond strength than these traditional salts. Also, the weakening of the adhesional strength by SD2 and CMA cannot be explained in terms of the effectiveness of component materials.
