再生玻璃粉增强聚丙烯泡沫混凝土的制备及性能研究
Study on Preparation and Properties of Recycled Glass Powder Reinforced Polypropylene Foam Concrete
研究旨在深入探究再生玻璃粉掺量对泡沫混凝土复合材料性能的影响,重点分析其对聚丙烯泡沫混凝土力学性能、耐久性及热学性能的提升效果,尤其是其在增强材料抗裂性、抗冻性和保温性能方面的作用。采用不同质量分数(0、10%、15%、20%、25%)的再生玻璃粉替代水泥,设计聚丙烯泡沫混凝土样品并测试其抗压强度、抗拉强度、抗冻融性能、孔隙结构和热导率等性能指标。结果表明:在10%~15%质量分数范围内,随着再生玻璃粉掺量的增加,聚丙烯泡沫混凝土的抗压强度和抗冻融性能得到显著提升。再生玻璃粉质量分数为15%时,泡沫混凝土的抗压强度达到9.3 MPa,抗冻融循环后的强度保留率为90%,质量损失率降至8%。再生玻璃粉的加入有效提高了聚丙烯泡沫混凝土的抗裂性和抗拉强度,并改善了材料的韧性。然而,当其质量分数超过15%时,聚丙烯泡沫混凝土的力学性能和耐久性出现下降趋势。在聚丙烯泡沫混凝土中使用再生玻璃粉替代水泥的最佳质量分数为10%~15%,能够显著改善力学性能和耐久性。研究结果为废玻璃资源化利用和泡沫混凝土性能优化提供新的思路和方向。
The study aims to thoroughly investigate the impact of recycled glass powder content on the properties of foamed concrete composite materials, with a particular focus on the enhancement of mechanical properties, durability, and thermal properties of polypropylene foamed concrete, especially in terms of improving crack resistance, freeze-thaw resistance, and thermal insulation performance. The research involved designing polypropylene foamed concrete samples with different mass fractions of recycled glass powder (0, 10%, 15%, 20% and 25%) as a replacement for cement, and testing their compressive strength, tensile strength, freeze-thaw resistance, pore structure, and thermal conductivity. The results indicate that within the mass fraction range of 10% to 15%, the compressive strength and freeze-thaw resistance of polypropylene foamed concrete significantly improve with the increase in recycled glass powder content. When the mass fraction of recycled glass powder is 15%, the compressive strength of the foamed concrete reaches 9.3 MPa, with a strength retention rate of 90% after freeze-thaw cycles and a mass loss rate reduced to 8%. The addition of recycled glass powder effectively enhances the crack resistance and tensile strength of polypropylene foamed concrete, and improves the material's toughness. However, when the mass fraction exceeds 15%, the mechanical properties and durability of polypropylene foamed concrete tend to decline. The optimal mass fraction range for using recycled glass powder as a cement replacement in polypropylene foamed concrete is 10% to 15%, which can significantly improve mechanical properties and durability. The findings provide new insights and directions for the utilization of waste glass and the optimization of foamed concrete properties.
