液态无（低）碱速凝剂以其优良的性能，逐渐取代传统速凝剂，成为新型速凝剂的代表。为便于更好地了解液态无（低）碱速凝剂的研究进展，从新型速凝剂的品种及其性能特点、促凝机理出发，着重分析了液态无（低）碱速凝剂在其适应性、稳定性、速凝机理、产量及价格、合理掺量及施工质量控制等方面存在的问题，探讨其进一步研究的方向。

Alkali-free or low-alkali liquid concrete accelerator has been going to replace the traditional accelerator by its excellent performance, and to become the representative of new accelerator. In order to better understand the research progress of alkali-free or low-alkali liquid accelerator, we presented the products, performance characteristics, and the accelerating mechanism of new accelerator, and analyzed  the existing problems in its adaptability, stability, accelerating mechanism, products and price,  reasonable dosage, and application quality control. We also discussed directions of further researches in this aspect.              
