In order to explore the preparation method of bottom ash alkali-activated materials for municipal solid waste incineration with higher efficiency,the mix proportion design,strength test and microscopic analysis of bottom ash alkali-activated materials were carried out.The effects of curing temperature and compressive strength development of bottom ash alkali-activated specimens with different mix proportions were analyzed.The polymerization mechanism was analyzed by XRD,SEM-EDS and FT-IR.The results show that when the particle size of bottom ash is less than 1.25 mm and the volume ratio of sodium silicate solution to sodium hydroxide solution is 2∶1,the increase of the content of granulated blast furnace slag(GBFS)will improve the compressive strength of the bottom ash alkali-activated specimens to a certain extent.The composite curing temperature under sealing condition is more conducive to the polymerization reaction and the formation of polymerization products.
