This study used silicon carbide sludge (SCS) and waste glass fiber (WGF) to prepare SCS/WGF porous (SWP) eco-fireproof materials by a hydrogen peroxide foaming agent. The results showed that the compressive strength of samples that were cured for 1 day and had an SCS replacement level of 10% and added amounts of WGF of 0.5% and 2.0% were 0.32 and 0.46 MPa, respectively. Additionally, it was observed that the stress–strain curves were relatively extended. WGF could improve the geopolymeric matrix of the composites in terms of formation and/or redistribution of cracks by bridging cracks and perforations within the matrix. When the added amounts of WGF were 0.5% and 2.0%, the reverse-side temperatures of the samples were 238 and 262°C, respectively, which showed that adding an appropriate amount of WGF could effectively reduce the reverse-side temperature of SWP eco-fireproof materials. The results displayed the beneficial influence of SCS and WGF in improving bulking density, compressive strength, and flexural strength and in reducing porosity and thermal conductivity. Therefore, the results showed that SWP eco-fireproof materials reinforced using SCS and WGF have potential as building materials.

阐明碳化硅污泥和废玻璃纤维对多孔生态防火材料特性的影响

本研究利用碳化硅污泥（SCS）和废玻璃纤维（WGF），通过过氧化氢发泡剂制备SCS/WGF多孔（SWP）生态防火材料。结果表明，固化1天、SCS替代水平为10%和WGF添加量为0.5%和2.0%的样品的抗压强度分别为0.32和0.46 MPa。此外，观察到应力-应变曲线相对延长。WGF 可以通过桥接基体中的裂缝和穿孔，在裂缝的形成和/或重新分布方面改善复合材料的地质聚合物基体。当WGF的添加量为0.5%和2.0%时，样品背面温度分别为238和262℃，表明加入适量的WGF可以有效降低SWP生态防火材料的背面温度。结果表明 SCS 和 WGF 在提高堆积密度、抗压强度和弯曲强度以及降低孔隙率和热导率方面具有有益影响。因此，结果表明使用SCS和WGF增强的SWP生态防火材料具有作为建筑材料的潜力。
