| Abstract | This thesis was undertaken to come up with a mix design that can be used for thin layer repairing of damaged taxiways and runways of an airport. The challenge was to provide a mix that is self-leveling in nature with high compressive and flexural strengths and with adequate bond strength between the new repairing material and the old substrate. Two level full factorial design (2k) with center points was adopted to analyze the results where k is the number of factors. A constant amount of superplasticizer (ViscoCrete 10) which 0.75% by the weight of cement and shrinkage compensating admixture (Anti shrinkage 40) which 1% by the weight of cement was used for the entire experiment process. 33 experiments were carried out and the obtained results were analyzed by Minitab18 software. All the 33 mixes were self leveling in nature with varying fresh and hardened properties. It was seen that 1-day responses were mostly affected by water cement ratio, 7-day responses were mostly affected by silica fume content and 28-day responses were mostly affected by fly ash content. It was observed that fly ash content, silica fume content and sand content of the mixes were affecting the bond strength with fly ash content affecting the most. The percentage of mass loss due to abrasion was seen to decrease with the increase in Silica Fume and Sand. The drying shrinkage was found to be under acceptable limits due to the application of Sika Anti Shrinkage 40. |
