摘　　要：为了降低腻子粉生产成本和拓展工业固废利用途径,本文研究了利用粉煤灰和钢渣制备建筑外墙用腻子粉的可行性,试验以粉煤灰、钢渣、水泥为主要原料,配加少量的羟丙基甲基纤维素和可分散性乳胶粉,制备了固废基建筑外墙用腻子粉,试验考察了粉煤灰和钢渣掺入量变化对应腻子粉性能变化规律。结果表明:在相同条件下,粉煤灰和钢渣占比为50%时,腻子粉黏结强度达最高,分别为0.83MPa和0.87MPa,较纯水泥时分别提高了29%和36%;当粉煤灰和钢渣占比为70%时,腻子粉黏结强度分别为0.62MPa和0.69MPa,均满足国家标准要求,显示出良好的应用前景。In order to reduce the production cost of putty powder and expand the use of industrial solid waste,this paper studies the feasibility of using fly ash and steel slag to prepare putty powder for building exterior walls.The experiment uses fly ash,steel slag and cement as the main raw materials.A small amount of hydroxypropyl methyl cellulose and dispersible latex powder were added to prepare putty powder for solid waste base building exterior wall.The experiment investigated the changes in the amount of fly ash and steel slag incorporation corresponding to the change in properties of putty powder.The results show that:under the same conditions,when the proportion of fly ash and steel slag is 50%,the bonding strength of putty powder reaches the highest,respectively 0.83 MPa and 0.87 MPa,which is increased by 29%and 36%compared with pure cement;when the proportion of fly ash and steel slag is 70%,the strength of putty powder is 0.62 MPa and 0.69 MPa,both of which meet the requirements of national standards,showing good application prospects.
