Concrete Durability after Load Damage and Salt Freeze–Thaw Cycles
Author(s) y Jiguo Zhou 1,*ORCID,Guihua Wang 1,Peng Liu 1,Xuefeng Guo Abstract To determine how the performance of concrete changes after initial load damage and salt freezing, concrete samples were first subjected to loading and unloading, and were then put...
Analysis of Carbonation Behavior of Cracked Concrete
Author(s) Qun Guo, Lexin Jiang, Jianmin Wang and Junzhe Liu Abstract The crack and carbonation of concrete pose a great challenge to its durability. Therefore, this paper studies the effect of cracks on the carbonation depth of cement paste under different...

Author(s) Hadee Mohammed Najm, Amer M. Ibrahim, Mohanad Muayad Sabri Sabri, Amer Hassan 1ORCID,Samadhan Morkhade 4,Nuha S. Mashaan, Moutaz Mustafa A. Eldirderi and Khaled Mohamed Khedher Abstract The composite shear wall has various merits over the traditional...
Durability Properties of Lightweight Foamed Concrete Reinforced with Lignocellulosic Fibers
Author(s) Md Azree Othuman Mydin, Mohd Nasrun Mohd Nawi, Ruba A. Odeh 3ORCID andAnas A. Salameh Abstract Worldwide concern and ascendancy of emissions and carbon footprints have propelled a substantial number of explorations into green concrete technology....
Using Geophysical Data to Quantify Stress Transmission in Gap-graded Granular Materials
Author(s) Masahide Otsubo* Reiko Kuwano† Catherine O'Sullivan‡ Thomas Shire§ Abstract The behaviour of gap-graded granular materials – that is, mixtures of coarse and cohesionless finer grains with measurable differences in particle size – does not always...
Interface Behaviour of Carbon-Fabric-reinforced Cementitious Matrix Composites with ICCP Technique
Author(s) Ran Feng Jingzhou Zhang Yanwen Li Ji-Hua Zhu Abstract This paper studies the interface bonding performance of carbon-fabric-reinforced cementitious matrix (C-FRCM) composites with the impressed current cathodic protection (ICCP) technique. Single...
A Semi-empirical Model for Bond Strength Between FRP Composites and Concrete
Author(s) Rami H. Haddad Nasser Al-Huthaifi Abstract An accurate estimate of fibre-reinforced polymer (FRP)–concrete bond is essential for a successful FRP repair. The present work aims at developing a semi-empirical model employing a large database (about 500...
Flange Contribution to the Shear Strength of RC T-Beams with Flange in Compression
Author(s) Osman M. Ramadan, Ahmed H. Abdel-Kareem 3,Ibrahim A. El-Azab and Hala R. Abousafa Abstract As is well known, in the current design codes, the shear strength of beams is calculated based on the modified truss theory, which does not consider the effects...
