... tensile strength. The findings contribute to the development of advanced, nanoengineered shotcrete materials for more resilient and sustainable infrastructure in challenging underground environments. EDS Durability Freeze-thaw Water ingression Workability Compressive strength SEM Graphene nano...

... mathematical models that most accurately describe the experimental findings. Findings The results demonstrate that SRCA notably improves the workability of fresh concrete due to its presaturation, which reduces water absorption and elevates the availability of free water. In contrast, mechanical strength...

... display, wiring, and mounted concrete specimens prepared for rapid chloride penetration testing. The workability of the fresh concrete was assessed using the slump cone test. These methods are standardized by the following Indian Standards: IS: 7320 (1974) reaffirmed in 2008 (Indian...

...% and 0.1% by weight of cement. The addition of GNP beyond 0.1% drastically reduced t he workability of concrete, as reported by the authors’ Jiang et al. (2021) and Khalid et al. (2018 . Therefore, in this study, the use of GNP was restricted to 0.1%. Cement, sand and coarse...

... to obtain HSC with 90 MPa and 16 cm of workability. For more general use of high-strength concrete (HSC), more research is necessary concerning the long-term properties, especially at early periods (Miiller and Kiittner, 1995). The size, shape, texture and grading characteristics of coarse aggregates...

... on the concrete’s fresh properties. The workability of the concrete mixture is a short-term property, but it is anticipated to affect the concrete’s long-term property. Design/methodology/approach In this review, the concrete and workability definition; concrete’s rheology models like Bingham model, thixotropy...

...) for all studied responses. The obtained results indicated that it is quite possible to substitute a part of cement with LF and PF in the formulation of a HPC. Thanks to the complementary effect between the two additions, the workability could be improved and the strengths drop could be avoided...

... Mixture design method was used for optimizing concretes characteristics and studying the effects of river sand (RS), dune sand (DS) and crushed sand (CS) in combinations of binary system and ternary on workability, the compressive and flexural strengths of concretes at 7 and 28 days. A total of 21...

.... Findings At 0.48 water cement ratio and 0.5% CNT by weight of cement workability reduced by 37% and water absorption reduced by 0.04%. But compressive strength, split tensile strength and flexural strength increased by 15.38, 33.02 and 15.75%, respectively, after 30 freeze thaw cycles. Also, weight loss...
