Behaviour of Engineered Cementitious Composite-encased Stub Concrete Columns Under Axial Compression
Author(s) Muhammad Khubaib Ilyas Khan Mohammad Masud Rana Yixia Zhang Chi King Lee Abstract Although high-strength concrete (HSC) has higher compressive strength than normal-strength concrete (NSC), its application in column construction is often limited by its...
Application of Light-burnt Dolomite as a Mineral Addition in Concrete
Author(s) Zhiyang Chen Min Deng Peng Liu Abstract Growth in the production of cement has led to increasing demands for mineral additions. This study was conducted to develop an alternative addition by calcining dolomite at 800°C to obtain a mixture of periclase...
Effect of Grinding on the Quantification of Bound Water in Tricalcium Silicate
Author(s) Shiju Joseph Özlem Cizer Abstract The effect of grinding hydrated tricalcium silicate (C3S) pastes on the bound water content (BWC) measured by thermogravimetric analysis was investigated. The samples were subjected to different curing regimes at 20°C...
Effects of Packing Density and Water Film Thickness on Fresh and Hardened Properties of Ternary Cement Pastes
Author(s) Guillermina Marchetti, PhD Edgardo Fabián Irassar, MEng Viviana Fátima Rahhal, Dr MEng Abstract Optimisation of the packing density of cementitious materials by the addition of supplementary cementitious materials (SCMs) is a way of obtaining the same...
Behaviour changes of ground granulated blast furnace slag geopolymers at high temperature Author(s)
Author(s) Ikmal Hakem Aziz Mohd Mustafa Al Bakri Abdullah Cheng-Yong Heah Yun-Ming Liew Abstract In this paper, the thermal performance of ground-granulated blast furnace slag (GGBFS) geopolymers is investigated. The geopolymers were prepared with sodium-based...
Modeling Early-Age Rheology of Cement-Silica Fume Pastes
Author(s) Jedadiah F. Burroughs, Charles A. Weiss Jr., John E. Haddock, and W. Jason Weiss Abstract This study presents the application of an analytical model to describe the rheological behavior of cement pastes containing silica fume at replacement rates of...
Evaluation of In-Place Stress in Concrete by Incremental Hole Drilling
Author(s) Ashutosh G. Dabli, Abhay N. Bambole, and Kamalkishor M. Bajoria Abstract The use of strain relief method is one of the most direct methods for determination of in-place stresses. In this method, a hole is drilled in the concrete member and the change...
Low-Velocity Impact Load Testing of RC Beams Strengthened in Flexure with Bonded FRP Sheets
Aouthor(s) Norimitsu Kishi, Ph.D., M.ASCE ; Masato Komuro, Ph.D. ; Tomoki Kawarai ; and Hiroshi Mikami, Ph.D Abstract In this paper, which focuses on the fiber-reinforced polymer (FRP) sheet bonding method for improving the impact resistance of RC beams,...
Optimization of Fiber-Reinforced Polymer Patches for Repairing Fatigue Cracks in Steel Plates Using a Genetic Algorithm
Auothor(s) Bach Do and Akhrawat Lenwari Abstract A practical design optimization of fiber-reinforced polymer (FRP) patches for repairing fatigue cracks in metallic structures is presented. The design procedure combines finite-element (FE), genetic programming...
