Fatigue Life Prediction in Cementitious Materials Through Bayesian Probabilistic Models
ABSTRACT First, we present a probabilistic framework for analyzing fatigue in cementitious materials, particularly concrete, within a Bayesian context. This is realized by incorporating the Sparks–Menzies relation, which correlates fatigue life to the secondary strain rate, into a probabilistic model.

Pulverized Calcined Clay and Carbide Waste as Alternative Binder in Concrete and Mortar Applications for Sustainable Construction [PDF]
Portland cement (PC) based concrete is the world’s most consumed man-made material and this consequently puts lots of demand on cement as a binder.

Effects of slag and superplasticizers on alkali activated geopolymer paste
Geopolymers are a type of amorphous alumino-silicate product, and can be synthesised by the polycondensation reaction of geopolymeric precursor and alkali polysilicates. The binder is prepared by the alkaline activation of industrial by-product materials

This study presents an integrated framework model designed for predicting the compressive strength of ultra‐high performance concrete (UHPC). The framework is structured into two primary modules, each comprising three sub‐modules: Module 1: Data collection and pre‐processing (data collection module, data cleansing module, and data preparation module ...

This study explores the strategic integration of Fused Deposition Modeling (FDM) for 3D‐printed reinforcement in concrete and cementitious materials. It identifies optimal reinforcement geometries, such as auxetic and truss structures, demonstrating their impact on flexural strength, ductility, and energy dissipation—advancing additive manufacturing in

Determining the strength of 3D printed concrete with the modified slant shear test
Abstract This study deals with the assessment of the load‐bearing capacity of layered 3D printed concrete (3DPC) using a modified slant shear test (MSST) to define a Mohr's envelope. To this aim, the established modified Coulomb yield condition of the concrete is complemented by a Coulomb failure criterion of the layer joints (cold or dry joints).
