No AccessImpact of Sodium Silicate Solution Chemistry on Product Formation and Jelly Hardening of Alkali-activated GGBS Mortars
Author(s) Lili Liu Yongsheng Ji Li Zhang Zhishan Xu Furong Ga Abstract This study investigated the effect of silicate modulus (M = silicon dioxide (SiO2)/sodium oxide (Na2O) by mass) and activator content S (mass proportion of sodium oxide and silicon dioxide...
Multiaxial Fatigue Life Assessment of Integral Concrete Bridge with a Real-Scale and Complicated Geometry Due to the Simultaneous Effects of Temperature Variations and Sea Waves Clash
Author(s) Hamid Abdollahnia, Mohammad Hadi Alizadeh Elizei and Kazem Reza Kashyzadeh Abstract components in the critical area was obtained by performing transient dynamic analysis. Various well-known equivalent stress fatigue theories (von Mises, Findley, Dang...
A Durability Prediction Method for Historical Square Rebar Reinforced Concrete Buildings
Author(s) by Hui Jin, Qing Chun, Chengwen Zhang and Yidan Han Abstract Square rebars were developed and used for decades in the early development of reinforced concrete (RC) structures; however, the objectives of modern concrete structure durability analyses...
Experimental and Numerical Studies on the Behaviors of Autoclaved Aerated Concrete Panels with Insulation Boards Subjected to Wind Loading
Author(s) Junkai Lu, Jie Chen, Kun Zhu, *,Hang Xu, Wenjia Zhang and Qing Deng Abstract Autoclaved aerated concrete panels (AACP) are lightweight elements in civil engineering design. In this paper, experiments and numerical analyses were conducted to study the...
Use of Bacteria Externally for Repairing Cracks and Improving Properties of Concrete Exposed to High Temperatures

Ground Waste Tire Rubber as a Total Replacement of Natural Aggregates in Concrete Mixes: Application for Lightweight Paving Blocks
Author(s) Matteo Sambucci and Marco Abstract The use of waste materials as alternative aggregates in cementitious mixtures is one of the most investigated practices to enhance eco-sustainability in the civil and construction sectors. For specific applications,...
Shrinkage Study and Strength Aspects of Concrete with Foundry Sand and Coconut Shell as a Partial Replacement for Coarse and Fine Aggregate
Author(s) Kalyana Chakravarthy Polichetty Raja, Ilango Thaniarasu, Mohamed Abdelghany Elkotb, Khalid Ansari 4ORCID andC Ahamed Saleel Abstract The demand for natural aggregates (river sand) is increasing day by day, leading to the destruction of the...
Strength and Toughness of Waste Fishing Net Fiber-Reinforced Concrete
Author(s) Tri N. M. Nguyen, Taek Hee Han, Jun Kil Park and Jung J. Kim Abstract In this study, we estimate the potential efficiency of waste fishing net (WFN) fibers as concrete reinforcements. Three WFN fiber concentrations (1, 2, and 3% by volume) were mixed...
Shear Behavior of Reinforced Post-Filling Coarse Aggregate Concrete Beams Produced by Creative Construction Process
Author(s) Jinqing Jia, Qi Cao, Lihua Zhang,Yulong Hu and Zihan Meng Abstract Different from the traditional concrete mixing procedure, the innovative post-filling coarse aggregate concrete (PFCC) reduces the cost of pumping concrete by increasing the coarse...
