可控性低强度材料（CLSM）是一种替代级配型传统回填材料,并具有低强度、自流平、自我填充与自密实特性,在欧美地区得到广泛应用。文章对一种典型的以水泥、粉煤灰和水为主要原材料的CLSM工程特性进行研究,分析其流动性能及力学性能受材料组成、龄期等因素影响下的变化发展规律。用水率与水泥掺量是影响其强度的两个主要因素,流动性主要受用水量的控制,受水泥掺量影响并不显著。

The controlled low strength material （ CLSM } is an alternative gradation traditional backfill material, it has characteristics of low strength, self- leveling, self- filling and self- compacting, and is widely used in Europe and American. The paper studied on the engineering properties of a typical CLSM that has cement, fly ash and water as the main raw materials, analyzed the change and development low of its flow performance and mechanical performance under the impact of material composition and age and so on. Water rate and cement content are the main factors that affect its strength. The mobility is mainly affected by the control of water consumption, not significant by cement content.
