1德国钢渣特性及其在路面工程中的综合利用显示文摘德国在钢渣处理方面有不少可以借鉴的地方。通过深入实际对德国钢渣的调查研究,详细报道了德国钢渣的主要种类,获取方式及不同工艺处理下各钢渣的特性,并对德国钢渣的排放及其在路面工程中的综合利用情况进行阐述,最后展望我国在钢渣性能改善及综合利用方面的发展前景及今后的研究趋势。赵青林 周明凯 Jochen STARK Ernst FREYBURG 2006公路2006,51,6:17
2The Mechanism of Ground Granulated Blastfurnace Slag Preventing Alkali Aggregate Reaction显示文摘Three different methods were applied to study the alkali content of gelpores in cement. In the closed system, the concentration of K+, Na+ and OH - have not reduced with the increase of age. In the open system, the diffusion and transferring of K+ and Na+ towards free space leads to the de-crease of total alkali content. In the micro-analysis system, the contents of K+ and Na+ in the first hy- drated layer of ground granulated blastfurnace slag (GBFS) are very low, while the contents of calcium and magnesium are relatively high. This phenomenon shows that the mechanism of GBFS preventing alkali aggregate reaction (AAR) is: when GBFS is dissolved by alkali medium, SiO2 and Al2O3 are dissolved into the cement matrix, then around GBFS particles form reaction rings rich in Ca2+ and Mg2+, and the C-S-H gel of positive charges formed in the area repulses K+ and Na+, which are forced to transfer to the mortar’s matrix, pore or mortar sample surface. The transferred K + and Na+ form alkali gel products with other dissolved ions, then become evenly distributed in the mortar sample and react with Ca(OH)2 in pore solutions to form (Na,K)x-2z·zCa·(SiO2)y·(OH)x gel products; and thus changes the AAR gel products’ structure. The gel products will not expand, and so they can delay expansion destruction.STARK Jochen FREYBURG Ernst 2010Journal of Wuhan University of Technology(Materials Science)2010,25,2:2
