The main objective of this comprehensive laboratory project was to investigate the potential use of acrylic latex to improve the physical and mechanical properties of thick superplasticised cement grouts. Experiments were conducted using different acrylic latex dosages with cement grouts that were prepared with water to cement ratios of 0·5, 0·4 and 0·33. The results indicated that the addition of acrylic latex of up to 5% significantly increases the 28 and 90 d strength, despite an extension of the setting time. The bleeding and resistance to acid attack of acrylic latex modified grouts were significantly improved. Grouts containing acrylic latex had much a higher viscosity and yield stress than the un-modified grouts. However, acrylic latex reduces the viscosity and yield stress of grouts that were prepared with water to cement ratios of 0·5 and 0·4 when added in small amounts. Based on the experimental results, non-linear regression analysis was performed to correlate the physical and mechanical parame...

Polyamine anti-stripping additives in asphalt mixes are chemical chains that bond chemically with an acidic siliceous aggregate at one end and an asphalt binder at the other. They help to prevent the hydro-oxide of siliceous aggregates from reacting with water molecules, which can lead to a breakdown of the asphalt mix. The effect of two proprietary polyamine-based anti-strippers, Wetfix and Tackamin-200, on moisture susceptibility, the resilient modulus and rutting performance were evaluated at percentages from 3 to 6% with increments of 0·1%. Wet and dry indirect tensile strength, the indirect tensile resilient modulus and dynamic creep tests were used to assess the moisture susceptibility, structural response and rutting resistance of treated asphalt mixes. The results indicated that 0·5% was the optimum dosage for both additives with respect to all performed tests, with Wetfix being more efficient. Overall, it was found that the impact of the anti-stripping agents on moisture susceptibility was signif...
