A multi-physics-based modelling approach to predict mechanical and thermo-mechanical behaviour of cementitious composite in a multi-scale framework
Concrete is a heterogeneous material whose constituents (e.g., cement paste, aggregate etc.) range from a characteristic length-scale dimension of a nanometre to a metre. Owing to the heterogeneity of concrete and the ...
Studies on Processed Granulated Blast Furnace Slag as Fine Aggregate in Mortars and Concrete
Fine aggregate is essential for the preparation of mortar and concrete. There are attempts to find alternatives to the river sand as the natural sources for fine aggregates are dwindling. Currently, sand mining from river ...
Experimental Investigations Into Fracture and Fatigue Behavior Of Plain and Reinforced Concrete Beams Using Acoustic Emission Technique
Concrete is the most widely used material in the world for construction of infrastructures and there are quite a few gaps in understanding its behaviour under different loads. Fracture in concrete occurs at pre-existing ...
Micromechanical modeling of fracture and fatigue behavior of cementitious composites
The ubiquitous use of concrete as a construction material in the civil engineering industry
demands a thorough understanding of its failure process under different types of loading.
The composite nature of cementitious ...
Studies on the Mechanisms of Fracture, Evolution of Microcracks and Size Effect in Concrete through Acoustic Emission Analysis
The mechanics of fracture evolution in heterogeneous material like concrete is a distinct and complex phenomenon and still stands as an open problem after decades of research. A cluster of multi-scale cracks ahead of the ...
Experimental studies on the fracture and fatigue failure processes under direct tension in quasi-brittle materials - Graphite and Concrete
Abstract
Fatigue phenomenon is a gradual, permanent, micro structural change that takes place
in a material due to the application of repeated loading. In the case of quasi-brittle
materials like graphite and concrete, ...
Fracture Processes in Sustainable Fibrous Cementitious Composites: Insights from Statistical Mechanics and Natural Time Analysis
In recent years, there has been a growing demand in the construction industry for slender, durable, and high performance structural elements. This has led to the development of an advanced cementitious composite material ...
Experimental investigations into tensile properties of large specimens and sensitivity of notch size on the fracture and fatigue behavior of concrete
Full text embargo upto Jan 15, 2027
Concrete, which is the second largest material used after water, is a highly heterogeneous
quasi-brittle material containing ingredients at different length scales. The fracture
and ...
Data-Driven Prediction of Concrete Behaviour and Performance Enhancement Through CO₂ Inclusion Techniques
Concrete remains the most widely used construction material globally, valued for its versatility, strength, and durability. However, the conventional approach to concrete mix design, governed by empirical codal provisions ...
