Stabilization of Silty Sand Using Blends of Polymer Emulsions and Hydraulic Cement for Airfield Construction

Blends of Type III Portland cement and select polymer emulsions were tested as potential soil stabilizers for airfield applications. The aim was to study increasing the early strength and curing time of emulsion polymer stabilization using blends of emulsion and Portland cement. Portland cement-stabilized specimens were prepared as conventional stabilizer controls. Each of the additives were added to a manufactured silty sand and compacted by a gyratory compactor at the optimum moisture content of 5% for the unmodified soil. Compacted specimens were cured in a controlled temperature and humidity environment for a maximum of 28 days. Samples were prepared at equivalent emulsion solids content of 2.75%. Portland cement was used at 6 and 9% dry weight for the control specimens and at 3% for the samples containing polymer/cement combinations. Stress-strain measurements were performed to determine the unconfined compressive strength and toughness under both wet and dry conditions. Results indicate that combinations of Type III Portland cement and polymer emulsions produce specimens with similar strengths and higher strains at yield compared to Type I and Type III cement alone. Cure time behavior indicates that the polymer-Type III soil cement blends build strength at a similar rate as Type III cement alone, yet may not have reached ultimate physical properties after 28-day cure times.
