以杂填土、钢渣、矿渣微粉为原料,采用土体固化技术混拌制备钢渣-杂填土基层材料。开展钢渣、混凝土破碎料、素土等主料对基层材料强度的耦合影响试验,构建回归模型,得到主料最优掺入比例,试验验证表明,回归模型预测值误差小于2%;以钢渣、混凝土破碎料、水泥、固化剂为因素开展正交试验,得到的最优结果与强度耦合影响试验基本一致,从而确定钢渣-杂填土最优配合比。最优配合比试件试验结果表明:钢渣-杂填土强度随龄期增长显著提升,30 d高温水浴膨胀率仅为1.03%。X射线衍射分析(XRD)及扫描电子显微镜(SEM)测试表明:矿渣微粉中SiO
2
与钢渣中f-CaO反应生成水化硅酸钙(C-S-H)凝胶,同时发现土壤固化剂对土体的改性可有效抑制钢渣膨胀;C-S-H凝胶填充于混凝土破碎料、钢渣、土颗粒间,增加了钢渣-杂填土基层材料密实度,使其强度得以提高。
Miscellaneous fill
steel slag
and slag powder were mixed to prepare steel slag-miscellaneous fill base material by soil solidification. Firstly
coupling influence test of main materials including steel slag
concrete crushed material and plain soil on the strength of base materials were conducted
regression model was established to obtain optimal mixing ratio. Experimental verification shows that the prediction error was within 2%. Secondly
the orthogonal test was carried out with steel slag
concrete crushing material
cement as well as curing agent as the factors
and the optimal results obtained were basically consistent with the strength coupling influence test. Thus
the optimal mix ratio of steel slag and miscellaneous fill was determined. The test results of the optimal sample showed that the strength increased significantly with age
which presented expansion rate of 1.03% after treatment 30 d high temperature water bath. X-ray diffraction analysis (XRD) and scanning electron microscope (SEM) test results show that SiO
2
in slag powder reacted with f-CaO in steel slag to form hydrated calcium silicate gel (C-S-H). It was also confirmed that the modification of the soil solidification agent to the soil can effectively prevent the expansion of steel slag; C-S-H gel is filled in the space of the broken concrete
steel slag as well as soil particles to increase the compactness of the steel slag-miscellaneous fill base material and thus enhance its strength.
