Properties of Soil-Based Flowable Fill under Drying–Wetting and Freeze–Thaw Actions

Flowable fills are a type of fill material with many construction applications, including transportation engineering, building water conservancy constructions, etc. usually consist cementing agents, water, and aggregates such as soils or other waste cheap materials. have the characteristics high flowability, self-leveling, self-compacting, adjustable strength, ability to adopt In this study, soil-based flowable was investigated under drying–wetting freeze–thaw actions. Under six cycles, specimens underwent continuous reduction in accompanying mass losses changes micro-structures. The level strength increased decreased addition Portland cement water. After showed 27–51% compared their counterparts no also noticeable but insignificant degradation. ranged from 9–20%. Most occurred during first three cycles. Based on test data, an empirical model proposed predict results proved that may undergo relatively large engineering performance adverse environments, especially implications for discussed paper.
