Application of Novel Radial Thresholding Method for the Segmentation of Different Phases from X-Ray Microtomographic Images of Concrete

Barai, Sudhirkumar; Pradhan, Subhasis (Springer, 2021)

Concrete is a composite material, which can be segmented into three major phases, namely voids, aggregates and mortar. This paper presents the digital image processing techniques based on grey value thresholding and a novel ...
Comparative LCA of recycled and natural aggregate concrete using Particle Packing Method and conventional method of design mix

Barai, Sudhirkumar; Pradhan, Subhasis (Elsevier, 2019)

In construction industry, apart from cement, the aggregate type, mix design method and transport distance of raw materials also contribute significantly to the environment related issues. This paper compares environment ...
Construction and Building Materials Shear performance of recycled aggregate concrete beams: An insight for design aspects

Barai, Sudhirkumar; Pradhan, Subhasis (Elsevier, 2018-07)

The shear failure of reinforced concrete beam is a brittle type of failure and can be dangerous if it is not properly designed. The inherent inferior quality of recycled coarse aggregate (RCA) makes the recycled aggregate ...
Impact of Particle Packing Method of Design Mix on Fracture Behavior of Concrete: Critical Analysis

Barai, Sudhirkumar; Pradhan, Subhasis (ASCE, 2020-04)

This paper discusses the effect of the particle packing method (PPM) of mix design on the fracture behavior of concrete. A three-point bending (TPB) test was performed on single-edge notched beam for three different sizes. ...
Impact of particle packing mix design method on fracture properties of natural and recycled aggregate concrete

Barai, Sudhirkumar; Pradhan, Subhasis (Wiley, 2018-11)

The fracture properties of four types of concrete prepared using natural coarse aggregate and recycled coarse aggregate and conventional and particle packing method (PPM) of mix design approaches are studied. The three-point ...
Impact of service life and system boundaries on life cycle assessment of sustainable concrete mixes

Pradhan, Subhasis (Elsevier, 2021-07)

Partial substitution of cement/clinker in concrete mix helps reduce its environmental impact. The supplementary cementitious materials such as fly ash and ground granulated blast furnace slag (GGBS), and limestone calcined ...
Multi-scale characterisation of recycled aggregate concrete and prediction of its performance

Barai, Sudhirkumar; Pradhan, Subhasis (Elsevier, 2020-02)

The inherent inferior quality of recycled coarse aggregate (RCA) influences the microstructural characteristics and consequently, the macro-mechanical properties of recycled aggregate concrete (RAC). The present paper ...
Partially hydrated recycled aggregate concrete: A systematic approach towards sustainable development

Barai, Sudhirkumar; Pradhan, Subhasis (Elsevier, 2018-10)

The experimental investigation on the mechanical properties of partially hydrated recycled aggregate concrete (PHRAC) with the addition of polypropylene fiber (PP fiber) is carried out and compared with the conventional ...
Performance of reinforced recycled aggregate concrete beams in flexure: experimental and critical comparative analysis

Barai, Sudhirkumar; Pradhan, Subhasis (RILEM, 2018)

The necessity of sustainable approaches in the construction sector persuades the researchers to utilize the recycled coarse aggregate (RCA) extracted from waste concrete and study the performance of structural members by ...
Recycled Aggregate Concrete: Particle Packing Method (PPM) of Mix Design Approach

Pradhan, Subhasis; Barai, Sudhirkumar (Springer, 2019)

The reuse of old concrete as a source of aggregate is a reliable alternative to Natural Aggregate (NA) in concrete construction. Because of poor quality of Recycled Aggregate (RA), the performance of Recycled Aggregate ...
Understanding the behavior of recycled aggregate concrete by using thermogravimetric analysis

Barai, Sudhirkumar; Pradhan, Subhasis (2020-12)

The physio-chemical changes in concrete mixes due to different coarse aggregate (natural coarse aggregate and recycled coarse aggregate (RCA)) and mix design methods (conventional method and Particle Packing Method (PPM)) ...
Use of machine learning based technique to X-ray microtomographic images of concrete for phase segmentation at meso-scale

Barai, Sudhirkumar; Pradhan, Subhasis (Elsevier, 2020-07)

The paper discusses the technical limitation of the gray value thresholding technique to detect the voids, aggregate and mortar phases. A two-stage image processing methodology is proposed for the segmentation of the three ...
