Science Citation Index Expanded (SClE); 2024 lmpact Factor: 0.1; Ei Compendex, etc.
Effective from Issue 6 in 2025, ZKG International (ISSN: 2366-1313) will be published by Tech Science Press (TSP). Bauverlag will remain fully responsible for the content and marketing of ZKG’s media products until the end of 2025. This transition aims to further strengthen the journal’s international visibility, academic influence, and publishing services for authors and readers worldwide.
ZKG International is currently published as a hybrid journal, offering both subscription-based and open access options for authors. In due course, the journal intends to transition fully to an open access model to increase the visibility and accessibility of its content.
The journal will continue to operate and be accessible through its established website: https://www.zkg.de/en/index.html.

Abstract Sprayed concrete is widely used in tunnel support and structural repair, but the direct addition of conventional viscosity-modifying agents often causes pipeline blockage and competitive adsorption with polycarboxylate superplasticizers, which leads to poor workability and high rebound rates. To overcome these practical problems, this study designs a mechanically triggered core–shell HPMC-40000 thickening agent (HPMC @ SiO2-TA) that can increase the instantaneous viscosity of mortar only when the material impacts the sprayed surface. The improvement effect of HPMC @ SiO2-TA on the performance of sprayed mortar was evaluated by apparent viscosity property, mechanical properties, bounce rate tests.… More >

Abstract Autogenous shrinkage is one of the primary factors leading to cracking in concrete structures. To enhance the efficiency of solid waste resource utilization, this study utilizes air-cooled blast furnace slag aggregates (ACBFSAs) to prepare concrete. The impact of different combinations of coarse and fine aggregates (NS-LCR, NS-SCR, SS-LCR, and SS-SCR) on the autogenous shrinkage of concrete is investigated. The experimental results indicate that the shape of the ACBFSAs is more irregular, and the surface of the aggregates is rougher. The 112 d autogenous shrinkage of the NS-LCR group reaches −195.4 μm/m. Replacing natural aggregates with More >
