Abstract
Replacing cement clinker by industrial by-products is important for their safe utilization and cost reduction. This study focused on multi-component ecological gelling material mainly consisting of granulated blast furnace slag (GGBS) powder with added fly ash, calcium carbide slag, phosphogypsum, and about 20% of PII cement. By means of compressive strength, mortar fluidity, leaching behavior, XRD, FTIR, TG and SEM, the effects of such key indices as the water-binder ratio and contents of cement, fly ash, calcium carbide slag, and GGBS on the working performance and mechanical properties of the proposed material were studied and discussed in detail. The best mechanical properties, with a 28 MPa strength reached in 7 days, were obtained at a water-binder ratio of 0.5, fly ash-to-GGBS ratio of 1:2, phosphogypsum-to-calcium carbide slag ratio of 1:2, and a 20% cement content. The Grey Relation Analysis (GRA) was used to analyze the influence of each component on the 3 d, 7 d, and 28 d strength, ranking them in the decreasing order as follows: GGBS, fly ash, cement, calcium carbide slag, and phosphogypsum. By combining the Grey Relation Analysis (GRA) with the experiment, the analysis results are more rigorous and the theory and experiment are combined. The results obtained are considered instrumental in optimizing multi-component ecological gelling materials for practical applications.
