Effects of Strain Rate and Strain Hardening on a Cantilever Under Impact
Authors: Ankur A. Kulkarni, PhD Abstract An investigation is carried out to assess the response of elastic–plastic and ductile circular section cantilevers subjected to blast wave loading. A mathematical equation is formulated for the effects of strain rate and...

Authors: Nadia Mokni* Agustín Molinero Guerra†‡ Yu-Jun Cui† Pierre Delage† Patrick Aimedieu† Michel Bornert† Anh Minh Tang† Abstract The aim of this paper is to investigate the long-term hydro-mechanical behaviour of a highly heterogeneous MX80 bentonite...
Lightweight Foamed Concrete Mixture for Structural Use
Author(s): Rabab Allouzi, Aya Al Qatawna, and Toqa Al-Kasasbeh Abstract Foamed concrete is currently studied to investigate its feasibility to be used structurally to produce a lightweight concrete mixture that is workable and has sufficient mechanical properties....
Mortar with Fly Ash and Rubber Waste and Crack Propagation Analysis
Author(s): A. Pczieczek, C. Effting, A. Schackow, I. Ribeiro Gomes, and D. V. Ferronato da Silva Abstract This work aimed to analyze the physical and mechanical properties of mortar with the addition of fly ash and rubber concentrations used on building walls. The...
Influential Parameters in Rheology of Alkali-Activated Binders
Author(s): Aparna Sai Surya Sree Nedunuri and Salman Muhammad Abstract The production of ordinary Portland cement (OPC) contributes enormously to global anthropogenic CO2 emissions and alkali-activated binders are one of the potential alternatives to OPC. To use...
Micromechanical Properties of Self-Healing Concrete with Crystalline Admixture and Silica Fume
Author(s): T. Chandra Sekhara Reddy, A. Ravitheja, and C. Sashidhar Abstract The study aimed at examining the capacity of diverse add-ons in improving the self-healing ability of fiber-reinforced concrete through low water-cement ratios (w/c) and exposure to wide...
Corrosion Resistance of Recycled Aggregate Concrete Incorporating Slag
Author(s): Anwar Al-Yaqout, Moetaz El-Hawary, Khallad Nouh, and Pattan Bazieth Khan Abstract The main objective of this paper is the investigation of the corrosion resistance of reinforced concrete containing various proportions of recycled aggregates (RA) combined...
A Large-deformation Random Finite-element study: Failure Mechanism and Bearing Capacity of Spudcan in a Spatially Varying Clayey Seabed
Authors: Jiang Tao Yi* Li Ying Huang* Dian Qing Li† Yong Liu‡ Abstract Although the random heterogeneity of a clayey seabed has been long recognised, it is relatively recently that the influence of spatial variability on the spudcan foundation has been explicitly...
Effect of Severe Chloride Environment on the Flexural Behaviour of Hybrid Concrete Systems
Authors: Luaay Hussein Lamya Amleh Hocine Siad Mohamed Lachemi Abstract This paper reports an investigation into the effect of a severe chloride environment on the flexural behaviour and microstructure of concrete composites combining normal- or high-strength concrete...
