摘要

近年来,严重削弱城市安全的地面沉降有加剧的趋势。本文的目的是利用工业副产物开发用于地面沉降应急恢复过程的材料。通过pH试验、初凝试验、无侧限抗压强度试验、流动试验等室内试验,对可控低强度材料(CLSM)的设计性能进行了评价。为评价CLSM的早期强度性能和应急修复的可操作性,进行了现场试验。试验结果表明,当水泥比大于4%时,地基强度过高,无法再开挖。当底灰与石膏的掺量约为50:50,水泥掺量为2%时,最佳掺量最有效。

Controlled Low Strength Material for Emergency Restoration Using Bottom Ash and Gypsum
Recently the ground subsidence which seriously weakens the safety of cities tends to increase. The purpose of this paper is to develop the materials by using industrial by-products for the application to emergency restoration process in case of ground subsidence. In this paper the laboratory tests including pH test, initial setting test, unconfined compressive strength test, and flow test were performed in order to evaluate the design properties of Controlled Low Strength Material (CLSM). The field test was carried out for evaluating the performance for the early strength of CLSM and the workability for emergency restoration. Test results showed that the strength will be too high to re-excavate the ground when the cement ratio is more than 4%. The optimum mixing ratio appears to be most effective when the mixing ratio of the bottom ash and the gypsum is approximately 50:50 and the cement content is 2%.
