“…ough the method of single variable and orthogonal design is often used to analyze the effects of various factors on targets, test quantity is large and the interaction among various factors cannot be analyzed [22]. Response surface methodology (RSM) is usually adopted to reflect the influence of the factors on the targets and their interaction with three-dimensional image, which is an integration method of mathematics and statistics.…”

Cemented coal waste backfill material (CCWBM) is developed for backfilling the goaf in coal mines. As fresh CCWBM slurry is generally transported into underground openings through a pipeline, the fluidity of fresh slurry becomes one of the most important properties. Adding superplasticizer is considered to improve the flow performance of the slurry without alerting the mechanical performance of filling body. e dosage of superplasticizer (SP) is related to filling cost, thus response surface methodology (RSM) is adopted to study the influence of material composition on SP when target slump is 250 mm. e effects of fly ash content, fine gangue ratio, and mass concentration on SP are analyzed using the software of Design-Expert and central composite design (CCD), and models are established for SP. Results show that the SP model coincides greatly with the test results and can be applied to analyze and predict SP in CCWBM. Mass concentration, fly ash content, and fine gangue ratio influence SP from high to low. e interaction of fine gangue ratio and mass concentration between SP is the most significant. e fact that the improved aggregate space model can be applied to analyze the fluidity of CCWBM is proved too. e research results provide guidance for the design and preparation of CCWBM with favourable performance and low cost in practical production.

“…Many scientific studies have revealed that some kinds of AAM are distinguished by superior durability and lower heat of hydration compared to OPC binder, high resistance to aggressive environments (Hossain et al, 2015) and good performance in high temperatures (Bernal et al, 2015). Another advantage could be better behaviour under freeze-thaw cycles (Cai et al, 2013). However, these materials exhibit drying and autogenous shrinkage (Bilek et al, 2016), the subsequent formation of microcracks and higher formation of salt efflorescence, which are the major drawbacks that hinder these materials' broader industrial application.…”

Alkali-activated materials, especially when activated by water glass, exhibit substantial drying shrinkage that hinders their broader industrial application. The effect of shrinkage-reducing admixtures (SRA), based on polypropylene glycol, on drying shrinkage of alkali-activated blast furnace slag (BFS) mortars was examined. The determination of SRA efficiency and the influence of potassium alkali activators with varying silicate modulus on drying shrinkage characteristics were studied. It was observed that a high amount of alkalis positively affected the effect of SRA. The higher the amount of alkalis was, the lower was the drying shrinkage. The paper further discusses and underlines the role of the amount of alkali ions on the properties of alkali-activated BFS systems.
