流态固化土是一种具有可泵性、自密实性以及强度可控性的新型岩土工程材料,可有效解决建筑工程产生的建筑渣土、废弃泥浆等固废材料的回收再利用问题.该文阐述了流态固化土制备方法及主要类型,分析了流态固化土流动性、强度和耐久性影响因素,总结了其工程应用及优势.研究表明:流态固化土是一种工程应用前景广阔的工程材料,流态固化土流动性主要受水固比影响,强度与固化剂掺量呈正相关.目前,流态固化土存在固化性能差异大、固化机理研究薄弱、施工产业化程度低等问题.因此,流态固化土新型固化剂的开发、流态固化土固化机理探究以及施工成套技术研发将是今后的研究发展趋势.
Factors Influencing the Characteristics of Flowable Stabilized Soil and Advances in Its Applications
Flowable stabilized soil is a novel geotechnical engineering material characterized by pumpability,self-compaction,and controllable strength.It offers an effective solution for recycling construction waste materials such as excavated soil and waste slurry.This paper discusses the preparation methods and main types of flowable stabilized soil,analyzes the factors influencing its flowability,strength,and durability,and summarizes its engineering applications and advantages.Research findings indicate that flowable stabilized soil has broad application prospects in engineering.Its flowability is primarily influenced by the water-to-solid ratio,while its strength is positively correlated with the dosage of stabilizers.However,challenges remain,such as variability in stabilization performance,limited understanding of stabilization mechanisms,and low industrialization levels in construction.Future research directions include the development of novel stabilizers,exploration of stabilization mechanisms,and the advancement of complete construction technologies for flowable stabilized soil.
