轻质隔墙板用小粒径膨胀珍珠岩的应用研究

摘要

The small particle size of waste expanded perlite is used to prepare lightweight partition board. The influence law of small expanded perlite admixture,fly ash content and total water/binder ratio on volume density,compressive strength and thermal conductivity of lightweight partition board is studied. The content of the small expanded perlite is in the range of 33.3%~41.7%. The content of fly ash is in 39%.The scope of the total water/binder ratio is 1.1~1.4. The production shows that the compressive strength ranges from 3.8~6.9 MPa,the dry density ranges from 706~827 kg/m3,the thermal conductivity is in a range of 0.1513~0.1859 W/(m·K).%利用废弃的小粒径膨胀珍珠岩制备轻质隔墙板,研究小粒径膨胀珍珠岩掺量、粉煤灰掺量、总水胶比对轻质隔墙板的体积密度、抗压强度和导热系数的影响规律,确定小粒径膨胀珍珠岩轻质隔墙板的配合比范围:小粒径膨胀珍珠岩掺量为33.3%~41.7%,粉煤灰掺量为39%,总水胶比控制在1.1~1.4;制得的轻质隔墙板抗压强度为3.8~6.9 MPa,干表观密度为706~827 kg/m3,导热系数为0.1513~0.1859 W/(m·K).
