摘要:
研究孔隙特征对泡沫混凝土基本性能的影响,可以为轻质泡沫混凝土在建筑领域的应用提供理论依据。文章制备了9种不同的泡沫混凝土,采用SZ61体视显微镜观察泡沫混凝土样品孔隙,利用软件Image-Pro plus 6.0计算泡沫混凝土孔隙孔径、孔表面积、孔圆度以及孔分形维数,研究泡沫混凝土孔隙平均直径、表面积、圆度及分形维数对表观密度和28 d强度的影响。结果表明:泡沫混凝土的表观密度和28 d抗压强度随孔隙孔径、孔表面积、孔圆度以及孔分形维数的增大而减小;泡沫混凝土的水胶会影响了孔隙的特征,当水胶比为0.4时,孔径、表面积和圆度变小,分形维数和泡沫混凝土的强度变大;泡沫混凝土孔圆度与泡沫混凝土的28 d强度有强的负相关性。
Abstract:
To study the effect of pore characteristics on the properties of foamed concrete can provide a theoretical basis for the application of lightweight foamed concrete in the construction field. 9 kinds of foam concrete were prepared. The pores of samples were observed and photographed by SZ61 stereoscopic microscope and the pore size, pore surface area, pore roundness and pore fractal dimension were calculated by image-Pro plus 6.0 software. The effects of average pore diameter, surface area, roundness and fractal dimension on apparent density and 28-day strength of foam concrete were studied. The apparent density and 28-day compressive strength of foamed concrete decrease with the increase of pore size, pore surface area, pore roundness and pore fractal dimension. The water-binder ratio of foamed concrete affects its pore characteristics. When the ratio is 0.4, the pore size, surface area and roundness become smaller, and the fractal dimension and strength of foamed concrete become larger. There is a strong negative correlation between the roundness of the foam concrete pore and the 28-day strength.
