粉土基泡沫轻质土的制备及性能研究

Preparation and Performance Study of Foam Light Soil Using Silt Soil as the Base

摘要: 本研究主要探讨了粉土基泡沫轻质土的制备工艺及其力学性能。通过在泡沫轻质土中掺入不同比例的粉土，分析了其对材料流动性、抗压强度及抗折强度的影响。结果表明，随着粉土掺量的增加，材料的流动性和力学性能呈现出一定的变化趋势。粉土掺量较低(如25%)时，材料性能较为优良，而较高的掺量(如50%)会导致强度显著下降。同时，经济效益分析显示，适量掺加粉土(如25%)能够有效降低材料成本，且能满足工程应用的质量要求。最终，本研究建议在实际工程应用中采用粉土掺量为25%的配合比，以获得较好的性价比和工程性能。

Abstract: In this study, the preparation technology and mechanical properties of silty base foamed light soil were discussed. The effects of different proportions of silt on the fluidity, compressive strength, and flexural strength of foamed light soil were analyzed. The results show that the fluidity and mechanical properties of the material change with the increase in silt content. When the silt content is low (e.g., 25%), the material performance is better, while the higher content (e.g., 50%) will lead to a significant decline in strength. At the same time, the economic benefit analysis shows that the appropriate amount of silt (such as 25%) can effectively reduce the material cost and meet the quality requirements of engineering applications. Finally, this study suggests that the mix ratio of silt content of 25% should be adopted in practical engineering applications to obtain better cost performance and engineering performance.
