摘要(Abstract)：

【目的】为了提高水库底泥的高值化利用率，拟使用水库底泥来制备泡沫混凝土，以水胶比、底泥掺量、泡沫掺量为变量【方法】采用Design-Expert 13.0软件中响应曲面法对水库底泥泡沫混凝土的配合比进行优化设计，分析变量对水库底泥泡沫混凝土抗压强度和导热系数的影响。采用SEM和XRD探究了底泥泡沫混凝土微观结构。【结果】研究结果显示，对水库底泥泡沫混凝土28 d抗压强度影响顺序为：水胶比>泡沫掺量>底泥掺量，而导热系数的影响顺序为：水胶比>底泥掺量>泡沫掺量。随着水胶比增加，抗压强度先升高后下降，导热系数逐渐降低。增加泡沫和底泥掺量会导致抗压强度和导热系数均下降。孔隙率与导热系数呈现负相关，符合指数模型。【结论】经优化配比，水库底泥泡沫混凝土在水胶比0.4、底泥掺量30%、泡沫掺量4.2%条件下制备，其28 d抗压强度为18.19 MPa,导热系数为0.121 4W/(m·K),表观密度为701.2 kg/m~3。微观结果分析表明，底泥掺入量为30%条件下，试块内部物相结合紧密，孔隙分布均匀。研究成果为水库底泥在建筑材料领域的利用提供了新途径。
