The effect of resin on treatment of soil-cement was studied through experimental tests. Three kinds of commercial resins with different percentage weights were used within the study.  Test samples were made of mixtures of soil with different percentage weights of cement (8 % and 12%) and mixing of soil-cement with different percentage contents of resin (5, 8 and 10%). Unconfined compression tests were conducted on the prepared samples at different curing times. Results indicated that adding resin to soil-cement causes increase in the strength of the mixture. In addition, an increase in the strength is a function of percent cement content, resin percentage, type of resin (viscosity of the resin) as well as curing time. A regression model was proposed as based on the experimental data for predicting the compressive strength. The regression model consisted of percentage content cement percent resin, kind of resin (resin viscosity) as well as curing time as variables. A comparison between the model predictions and the experimental results reveals that the proposed models can satisfactorily predict the compressive strength as regards soil-cement resin mixtures.
