| 1 | Stabilization Mechanism of Calcium Lignosulphonate Used in Expansion Sensitive Soil显示文摘A series of tests were performed to investigate the macroscopic properties and the stabilization mechanism of calcium lignosulphonate modified expansive soil.Compared with natural soil,soil modified by 4%calcium lignosulphonate showed 56.5%increased 28 days unconfined compressive strength and 23.8%decreased free expansion rate.The X-ray diffraction analysis results indicate the existence of cation exchange and the reduction of montmorillonite interplanar spacing.The X-computed tomography results demonstrate that calcium lignosulphonate decreased the porosity and optimized the pore distribution.The calcium lignosulphonate also increased the stability of the suspension system according to the Zeta potential results.Moreover,the results of rheological tests show that the moderate amount of calcium lignosulphonate enhanced the yield stress and the plastic viscosity,proving the formation of a strong connection between soil particles. | 吴大江 佘伟 WEI Luansu ZUO Wenqiang HU Xiangyu HONG Jinxiang MIAO Changwen | 2020 | Journal of Wuhan University of Technology(Materials Science)2020，35，5： | 2 |
| 2 | Incorporation of a nanotechnology-based additive in cementitious products for clay stabilisation显示文摘The mechanical performances and water retention characteristics of clays,stabilised by partial substitution of cement with by-products and inclusion of a nanotechnology-based additive called RoadCem(RC),are studied in this research.The unconfined compression tests and one-dimensional oedometer swelling were performed after 7 d of curing to understand the influence of addition of 1%of RC material in the stabilised soils with the cement partially replaced by 49%,59%and 69%of ground granulated blast furnace slag(GBBS)or pulverised fuel ash(PFA).The moisture retention capacity of the stabilised clays was also explored using the soil-water retention curve(SWRC)from the measured suctions.Results confirmed an obvious effect of the use of RC with the obtained strength and swell properties of the stabilised clays suitable for road application at 50%replacement of cement.This outcome is associated with the in-depth and penetrating hydration of the cementitious materials by the RC and water which results in the production of needle-like matrix with interlocking filaments e a phenomenon referred to as the‘wrapping’effect.On the other hand,the SWRC used to describe the water holding capacity and corresponding swell mechanism of clays stabilised by a proportion of RC showed a satisfactory response.The moisture retention of the RC-modified clays was initially higher but reduced subsequently as the saturation level increased with decreasing suction.This phenomenon confirmed that clays stabilised by including the RC are water-proof in nature,thus ensuring reduced porosity and suction even at reduced water content.Overall,the stabilised clays with the combination of cement,GGBS and RC showed a better performance compared to those with the PFA included. | E.U.Eyo S.Ng’ambi S.J.Abbey | 2020 | Journal of Rock Mechanics and Geotechnical Engineering2020，12，5： | 2 |
| 3 | 水泥-硅粉改性膨胀土的性能研究显示文摘膨胀土在工程中表现出高膨胀、收缩和开裂的特性,会显著影响建筑地基的稳定性。以合肥地区中膨胀土为研究对象,水泥和硅粉作为改性材料,研究改性膨胀土的干缩特性。试验结果表明:水泥可以显著改善膨胀土的干缩性,水泥含量为12%时,试样总收缩量从22.3%降低到10.5%;总添加剂含量一定时,改性土的干缩性随硅粉增加而改善;水泥与硅粉按9:1质量比配制添加剂,改性效果较好;提出的改性膨胀土干缩模型的计算值与试验值吻合度较好,具有显著的实用性。 | 马露 徐晓阳 | 2020 | 辽宁科技学院学报2020，22，6： | 1 |
