摘要/Abstract

摘要： 本研究以水泥为主要材料,旨在探讨拌合水温及双氧水比例对发泡水泥力学性能、保温性能和孔隙结构的影响。通过调节水温(40、50、60 ℃)和双氧水比例(6%、7%、8%,质量分数),采用化学发泡方法制备不同密度的发泡水泥,并对其抗压强度、导热系数及孔隙结构进行了系统分析。结果表明,当水温控制在50 ℃,双氧水比例7%(质量分数)时,发泡水泥的抗压强度可达1.93 MPa,此时导热系数为0.054 1 W/(m·K),泡孔分布均匀,孔隙结构致密。通过合理调控双氧水质量分数和水温,可以显著提升发泡水泥的抗压强度和保温性能,同时还可优化其孔隙结构分布,提升发泡水泥整体性能。

关键词: 发泡水泥, 双氧水, 抗压强度, 导热系数, 孔结构

Abstract: This study used cement as the primary material to investigate the effects of mixing water temperature and proportion of hydrogen peroxide on the mechanical properties, thermal insulation, and pore structure of foamed cement. By adjusting the water temperature (40, 50, 60 ℃) and proportion of hydrogen peroxide (6%, 7%, 8%, mass fraction), cement with varying densities were prepared via the chemical foaming method. The compressive strength, thermal conductivity, and pore structure of the foamed cement were thoroughly analyzed. The results show that when the water temperature is controlled at 50 ℃ and the proportion of hydrogen peroxide is 7%, the compressive strength of the foamed cement reaches 1.93 MPa, the thermal conductivity is 0.054 1 W/(m·K), the pore distribution is uniform with a dense structure. By appropriately regulating the proportion of hydrogen peroxide and water temperature, the compressive strength and thermal insulation performance of foamed cement can be significantly enchanced. At the same time, the pore structure distribution can be optimized, and the overall performance of foamed cement can be improved.

Key words: foamed cement, hydrogen peroxide, compressive strength, thermal conductivity, pore structure
