Influence of surface cracking, anchor head profile, and anchor head size on cast-in headed anchors in geopolymer

Frontiers of Structural and Civil Engineering   Pages 1163-1187 doi: 10.1007/s11709-023-0987-5

Abstract: concrete cone capacity, concrete cone angle, and load–displacement response of cast-in headed anchors in geopolymerThe tensile behavior of anchors in geopolymer concrete is compared with that in normal concrete as wellThe results show that the capacity of the anchors in geopolymer concrete is 30%–40% lower than that inThe results also indicate that the CCD model overestimates the capacity of the anchors in geopolymer

The Durability of Alkali-Activated Materials in Comparison with Ordinary Portland Cements and Concretes: A Review Review

Aiguo Wang, Yi Zheng, Zuhua Zhang, Kaiwei Liu, Yan Li, Liang Shi, Daosheng Sun

Engineering 2020, Volume 6, Issue 6,   Pages 695-706 doi: 10.1016/j.eng.2019.08.019

Abstract:

China is the largest producer and user of ordinary Portland cement (OPC), and the rapid growth of infrastructure development demands more sustainable building materials for concrete structures. Alkaliactivated materials (AAMs) are a new type of energy-saving and environmentally friendly building material with a wide range of potential applications. This paper compares the durability of AAMs and OPCbased materials under sulfate attack, acid corrosion, carbonation, and chloride penetration. Different AAMs have shown distinct durability properties due to different compositions being formed when different raw materials are used. According to the calcium (Ca) concentration of the raw materials, this paper interprets the deterioration mechanisms of three categories of AAMs: calcium-free, low-calcium, and calcium-rich. Conflicts found in the most recent research are highlighted, as they raise concerns regarding the consistence and long-term properties of AAMs. Nevertheless, AAMs show better durability performances than OPC-based materials in general.
