This review examined the effects of construction joints, particularly cold joints, on reinforced concrete beams'' structural performance and integrity.
Cold joints that occur in concrete significantly affect the performance and durability, so that further analysis and research needs to be done on the strength of concrete due to the cold joint.
To reveal their impacts on tunnel service performance, indoor tests and theoretical analysis are used to assess the mechanical properties of concrete with cold joints, including elastic
Cold joints are weak areas of tunnel lining structure, which form due to the discontinuous pouring of concrete. To reveal their impacts on tunnel service performance, indoor tests and
Cold-joint interface behaviour analysis was performed by predicting the shear stress and slippage values using the proposed analytical method, by
This study would to test the compressive and flexural strength due to the effect of cold joint in the concrete.
This review examined the effects of construction joints, particularly cold joints, on reinforced concrete beams'' structural performance and integrity. Cold joints, which form when concrete is poured in
Learn about cold joints in concrete, their causes, prevention methods, and effective repair techniques to ensure structural integrity and durability.
Conference paper written by Anca C. Ferche, Brandon Li, Hwa-Ching Wang, Elias I. Saqan and Oguzhan Bayrak presented at IABSE Symposium: Bridging Advanced Technologies - Structural
A cold joint, a critical consideration in concrete construction, arises when a fresh batch of concrete is placed against a previously hardened or partially hardened concrete surface. This discontinuity can
The review explored how cold joints impacted key properties like flexural strength, ductility, and energy dissipation capacity, drawing on numerous
By minimizing the number of construction joints and ensuring that any unavoidable joints are treated meticulously with construction joint preparation techniques and concrete bonding agents,
The usage of the NSC may lead to larger volumes of concrete, which results miss leading in the cost of structure. On the other hand, the usage of only HSC may lead to over estimated cost to an ordinary
To better understand the behaviour of cold joints subjected to these thermal fatigue cycles, an experimental program was conducted at the University of Manitoba, focusing on the performance
Cold joints that occur in concrete significantly affect the performance and durability, so that further analysis and research needs to be done on the strength of concrete due to the cold joint.
This study investigated the effects of cold joints on the strength and some durability properties of concrete. In the first part of the study, fresh concrete was poured into molds filling them half in order
Three types of specimens were tested for the interlayer adhesion strength: non-cold joint, treated cold joint, and untreated cold joint. For the non-cold joint, the specimens were printed
Despite existing studies on the deterioration of bearing performance in concrete with cold joints, the formation mechanism and characteristics of cold joints, as well as the identification
Hot vs Cold Joint is a fundamental distinction in assembly and joining techniques, particularly significant in industrial design and manufacturing processes. Hot joints, also known as heat bonds, involve the
This experimental study investigates the influence of interlayer orientation and the presence of cold joints (CJ) on mechanical properties, such as stiffness and strength.
Cold joints, formed due to interruptions in the concrete placement process, significantly impact the mechanical behavior of concrete structures. This study comprehensively examines the
Concrete specimens with and without cold joints were subjected to drying–wetting, freezing–thawing and high temperatures (300, 600 and 900 °C) and subsequently tested for weight losses and splitting
Learn everything about working with cold joints in concrete. This article covers causes, effects, and solutions for managing cold joints to ensure strong and durable concrete structures.
Cold joints significantly reduce compressive and flexural strength in concrete, especially with longer casting delays. This study tests concrete types: normal, high compressive with superplasticizer, and
