Abstract: In order to realize the comprehensive utilization of gasified ash and reduce the cost of putty powder production，the technical feasibility of using gasified ash to replace the cement to prepare putty powder was experimentally studied. The gasified ash and 42. 5 cement were used as the main raw materials，and a small amount of hydroxypropyl methylcellulose and dispersible latex powder were used to prepare the gasified ash-based putty powder. The effects of changes in the formulation of the raw materials on the performance of the putty powder were experimentally investigated. The research results showed that it was feasible to use gasified ash to replace cement products to prepare putty powder. Among them，when the gasified ash replaces 50% cement，the bond strength of the putty powder reached up to 0. 82 MPa，and all properties were better than the requirements of JG /T 157—2009 standard for putty powder of building exterior walls. Under the same conditions，when the gasified ash replaces no more than 70% of the cement，the bond strength and other indicators of the putty powder met therequirements of the putty powder standard JG /T 157—2009 for building exterior walls.

摘要： 为实现气化灰综合利用和降低腻子粉制备成本，研究了利用气化灰替代水泥制备腻子粉的技术可行性。以气化灰和 42.5水泥为主要原料，配以少量的羟丙基甲基纤维素和可分散性乳胶粉，制备气化灰基腻子粉，实验考察原料配方变化对腻子粉的性能影响。研究结果表明：利用气化灰替代水泥制品制备腻子粉具有可行性。其中，气化灰替代 50%水泥时，腻子粉的粘结强度为 0.82 Mpa，各项性能均优于建筑外墙用腻子粉标准 JG/T 157—2009要求。在相同条件下，气化灰替代不超过 70%的水泥时，腻子粉的粘结强度及其他指标均满足建筑外墙用腻子粉标准 JG/T 157—2009要求。
