Two routes were compared: ball milling of halloysite (MBHA), generating fragmented surfaces with more active sites, and HTAB-assisted surfactant functionalization (MHHA), promoting hydrophobic interactions.

While the two-step flocculation process is a promising approach to overcome this bottleneck, optimization is impeded by the unclear microscopic mechanism underlying sequence effects. Combining molecular dynamics (MD) simulations and kaolinite sedimentation tests, this study reveals how the dosing sequence of hydrophobic associative cationic flocculant (PAMT) with conventional flocculants (CPAM, APAM, NPAM) affects flocculation mechanisms. Results demonstrated that dosing PAMT first effectively controls particle aggregation and the interfacial microenvironment. Employing the sequence of PAMT followed by APAM (P + A combination) reduced turbidity to 31.50 NTU and increased initial settling rate to 92.88 m/h, thereby overcoming the functional limitations of single flocculants. Mechanistically, prior PAMT addition activated the dual-surface characteristics of kaolinite, forming a hydrogen bond network on the aluminol surface and enhancing electrostatic anchoring on the siloxane surface. Simultaneously, hydrophobic fluorocarbon chains of PAMT reduced interfacial water density, weakening the hydration layer and promoting dewatering. The P + A combination leveraged charge complementarity between the cationic and anionic flocculants, forming extensive and continuous molecular chain distributions on the kaolinite surface, which established a stable flocculation bridging mechanism. In the reverse sequence (A + P combination), the steric hindrance layer formed by APAM on the particle surface restricted contact with the hydrophobic groups of PAMT, hindering intra-floc hydrophobic association. Additionally, combinations involving CPAM (P + C, C + P) exhibited dosage sensitivity due to electrostatic repulsion between molecular chains, while those incorporating nonionic NPAM (P + N, N + P) showed weakened synergy due to the absence of ionic charges.</div></div>","PeriodicalId":245,"journal":{"name":"Applied Clay Science","volume":"284 ","pages":"Article 108122"},"PeriodicalIF":5.8,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146025286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because reactivity depends on phyllosilicate type as well as content, and clays vary widely, a quick and simple test is needed to assess raw material suitability. Therefore, the aim of this study was to investigate the mineralogical and physical properties of common clays and their impact on reactivity after MCA, as well as their suitability as SCM. Hence, a multi-method approach was used to determine the reactivity of seven German common clays after TA and MCA and their use as SCM. The R<sup>3</sup>-test was used to determine the evolved heat after 7 days. Thermal analysis showed an altered OH binding that went along with a decrease in surface area with prolonged milling. Through Rietveld refinement of the X-ray diffraction analysis and the external standard method, the amorphous content of the phyllosilicates was determined. An increase in the amorphous content was observed after MCA. The solubility of Al and Si could also be correlated with the reactivity of the phyllosilicates. The concentration of all ions increased with prolonged milling time, and therefore also correlated linearly with the reactivity.
