摘　　要：无碱液体速凝剂是一种能促进水泥或混凝土快速凝结、硬化,并在短时间内产生一定强度的混凝土外加剂。本文将硫酸铝型液体速凝剂分为硫酸铝系列、聚合硫酸铝系列、硫酸铝与氟化镁铝系列及其他系列,并从研究现状、制备方法、性能特点对其进行综述,提出无碱液体速凝剂未来发展趋势。Alkali-free liquid accelerator is a kind of liquid admixture which can promote cement or concrete to coagulate and harden quickly and produce certain strength in a short time.In this review,alkali-free liquid accelerators containing aluminum sulfate were divided into aluminum sulfate series,polyaluminum sulfate series,aluminum sulfate and magnesium aluminum fluoride series and other series.The current research status,preparation methods and performance characteristics of these liquid accelerators were reviewed.And the development trend of alkali-free liquid accelerators in the future was thereby proposed.
