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...
Watching the Bonding Between Steel Rebar and Concrete with in Situ X-ray imaging
Authors: Rudney Bostel Ana Carolina Parapinski Dos Santos Joao Bernardino Lopes Fabio Luiz Willrich Marcelo Goncalves Hönnicke Abstract Pull-out tests combined with an in situ radiographic movie are presented in order to investigate bond properties between steel rebar...
Review of Concrete Resistance to Abrasion by Waterborne Solids
Author(s): Nicholas Omoding, Lee S. Cunningham, and Gregory F. Lane-Serff Abstract In the last four decades, numerous investigations have been undertaken on abrasion-erosion of concrete using various test methods. These have suggested the existence of different...
Effect of Steel Fiber on Engineering Properties of Geopolymer Concrete
Author(s): Nabeel A. Farhan, M. Neaz Sheikh, and Muhammad N. S. Hadi Abstract The effects of aspect ratio and volume fraction of steel fibers on the engineering properties of ambient-cured geopolymer concrete (GPC) were investigated. Straight macro steel fibers with...
Analysis of Pore Solution of Different Cements with and without Admixed Chlorides
Author(s): Colin B. Van Niejenhuis, Ibrahim G. Ogunsanya, and Carolyn M. Hansson Abstract The pore solution expressed from 28-day cement pastes was analyzed as part of a wider research program investigating the corrosion behavior of stainless-steel reinforcing bars in...
Chloride Diffusion Models for Type V and Silica Fume Cement Concretes
Author(s): M. M. Al-Zahrani, K. A. Alawi Al-Sodani, M. Maslehuddin, O. S. Baghabra Al-Amoudi, and S. U. Al-Dulaijan Abstract One of several methods used to minimize reinforcement corrosion is the use of service-life prediction models to calculate mixture design and...
A Summary of Factors Affecting Concrete Salt-Scaling Performance
Author(s): Kamran Amini, Kristen Cetin, Halil Ceylan, and Peter C. Taylor Abstract This paper compiles results from three different laboratory studies and employs multivariate regression analyses to model the effect of mixture parameters and concrete hardened...
Effect of PH Value on the Growth and Properties of Magnesium Phosphate Cement Paste with a Large Water-to-solid Fraction
Authors: Mengtian Li Xiao Zhang Bin Han Dong Tian Abstract In this study, the effect of pH value, a neglected but important factor of magnesium phosphate cement (MPC) pastes, was investigated to generate new ideas in the field of large water-to-solid (w/s) fraction...
Prediction of Carbonation using Reactivity Test Methods for Pozzolanic Materials
Authors: Vineet Shah Anuj Parashar Satya Medepalli Shashank Bishnoi Abstract The influence of the capacity of supplementary cementitious materials (SCMs) to consume portlandite on the carbonation resistance of mortar was investigated. Seven different mineral additives...
