为了将生活垃圾焚烧底灰（MSWI-BA）进行资源化利用，基于响应面中心复合试验法（RSM-CCD）研究了不同活性激发方式对经过预处理的MSWI-BA水泥胶砂试块28 d抗压强度的影响.结果表明：活性激发MSWI-BA胶凝材料具有较好的胶凝活性；采用RSM-CCD得到，掺10%MSWI-BA水泥胶砂试块在最佳试验条件下的28 d抗压强度计算值为46.04 MPa，实测值为46.15 MPa，二者符合较好，为MSWI-BA的资源化利用提供了一种解决方法；MSWI-BA胶凝材料的安全性较好，重金属浸出性能满足GB 30760—2014《水泥窑协同处置固体废物技术规范》的要求.
To recycle the municipal solid waste incineration bottom ash（MSWI-BA）， the effects of different active excitation methods on the 28-day compressive strength of mortar test blocks prepared by pretreated MSWI-BA were studied by the method of response surface central composite test method(RSM-CCD). The results show that the MSWI-BA cementitious material has good cementitious activity by active excitation. The RSM-CCD test simulates that the 28-day compressive strength of the cement mortar test block with 10% MSWI-BA reaches 46.04 MPa under the optimal experimental conditions. Under this condition， the 28-day compressive strength of the cement mortar test block reaches 46.15 MPa， which is highly coincident with the predicted value. This method provides a solution for the resource utilization of MSWI-BA. Finally， the safety of the cementitious material is evaluated. The leaching performance of heavy metals meets the requirements of GB 30760—2014 Technical Specification for Coprocessing of Solid Waste in Cement Kiln.
