【摘要】：为了研究玄武岩纤维掺量对泡沫玻璃性能的影响,以粉煤灰、玻璃粉、玄武岩纤维及外加剂制备泡沫玻璃,分析不同掺量下玄武岩纤维对泡沫玻璃物理性能、力学性能和导热系数的影响。研究结果表明:随着玄武岩纤维掺量的增加,泡沫玻璃的表观密度、导热系数呈递增趋势,当玄武岩纤维掺量为3‰-4‰时,表观密度变化较为平缓;当玄武岩纤维掺量为1‰时,导热系数达到0.0631 W/(m·K),当玄武岩纤维掺量在1‰-5‰时,对泡沫玻璃的含水率、吸水率影响较小,分别维持在0.35%、15%左右;当玄武岩纤维的掺量在1‰-4‰时,泡沫玻璃的抗压、抗折强度逐渐增大,掺量在4‰时,试样的抗压、抗折强度达到8.28 MPa和0.75 MPa,相比于基准试样,分别提高了2.24倍和1.92倍。
[Abstract]:In order to study the effect of basalt fiber content on the properties of foamed glass, the foamed glass was prepared with fly ash, glass powder, basalt fiber and admixture, and the physical properties of foam glass with different content of basalt fiber were analyzed. Effects of mechanical properties and thermal conductivity. The results show that the apparent density and thermal conductivity of foamed glass increase with the increase of basalt fiber content. When the content of basalt fiber is 3 鈥，
