摘要

摘要本文提出了一种基于新型替代粘结剂的道路施工土壤稳定新技术。该项目旨在评估替代添加剂材料在道路建设土壤稳定环境中的效果。替代粘结剂(矿渣、能源灰和生物灰作为新型道路建筑材料)已被用于补充传统粘结剂(水泥和石灰)。该项目使用了五种粘结剂,并评估了它们对土壤强度的影响。所提出的方法包括使用替代粘合剂的优点,这些粘合剂是有助于降低环境影响的残余产品。结果表明,只有矿渣对稳定土的强度有显著影响,生物灰和能量灰对稳定土强度的提高贡献较小。这是由双重原因造成的。首先,灰的数量应该达到一定的阈值,相对于粘合剂的总量,必须超过这个阈值才能产生土壤混合物的效果。二是生物粉煤灰贮存时不完全新鲜,可能在贮存期间碳化,导致其硬化能力较低。根据研究结果,我们建议使用生物粉煤灰作为供应材料,并对其用量进行调整,以使储存期不会太长。本研究验证了矿渣、水泥和石灰对道路施工土的稳定作用。

Effects of GGBS and Fly Ash in Binders on Soil Stabilization for Road Construction
Abstract In this paper we propose a new technique of soil stabilization for road construction based on using new alternative binders. The project aims to evaluate the effects of alternative additive materials in soil stabilization contexts for road construction. The alternative binders (slag, energy ash and bio ash as new alternative road construction material) have been used to complement the traditional binders (cement and lime). The project used five binders and evaluated their effects on soil strength. The proposed method comprises advantages of using the alternative binders which are the residual products contributing to a lower environmental impact. The results have shown that only slag has significant effects on the strength of the stabilized soil, while bio ash and energy ash make a marginal contribution to the increase of strength. This is caused by the twofold reasons. First, the effects of the amount of ashes that should reach a certain threshold with respect to the total amount of binder that must be exceeded to have the effect of the soil mixture. Second, the bio fly ash was stored and it was not completely fresh which may have contributed to the carbonation during the storage period and results in a lower hardening ability. Based on the results of the study we recommend the use of bio fly ash as a supply material andfor its amount to be adjusted so the storage period is not too long. This study verified the effects of slag, cement and lime on stabilization of soil for road construction.
