| Abstract | This present paper investigates influential factors (water content, cement content, fly ash content and curing time) on strength development in saline soiladmixed with cement and fly ash. It is found that for a particular cement content, the strength of admixed saline clay increases with fly ash content and the highest strength is attained at 25% fly ash. Fly ash disperses the soil-cement clusters into smaller clusters and increases the reactive surface, hence strength improvement. Based on the clay-water/cement ratio and the parameter equivalent cement content, the strength prediction equation for the cement admixed saline soil is introduced. For fly ash content less than 25%, fly ash content is equivalent to 0.75 cement content for all combinations of water content, cement content and fly ash content. |
