Author(s) Sifatullah BahijS afiullah Omary, Vincent Steinerb, Françoise, Feugeas, and Mohammad Hashim Ibrahimkhil Abstract This study will investigate the effect of non-woven PET plastic tissue on the fresh, physical, mechanical, acoustic, thermal, and...
A Sustainable Alternative for Green Structural Lightweight Concrete: Performance Evaluation
Author(s) y Fahad K. Alqahtani Abstract The use of structural lightweight concrete in the construction industry is on the rise in the last few decades mainly because of the higher strength per unit density, as it reduces the total deal load of the structural...
Parametric Study on Steel–Concrete Composite Beams Strengthened with Post-Tensioned CFRP Tendons
Author(s) Ahmed H. Elbelbisi 1,2,Alaa A. El-Sisi, Hilal A. Hassan, Hani A. Salim and Hesham F. Shabaan Abstract A sustainable environment can be achieved by strengthening the existing building to avoid new construction and by replacing the construction...
Investigation into the Quasi-plasticity Damage Model for Concrete with Micropores Based on Peridynamics
Author(s) Wen-Liang Qiu Rong-Xin Peng Abstract The non-linear performance of concrete is determined by the heterogeneous micro-structure of concrete. The existing methods mainly focus on numerical simulation of concrete at meso-scale.In view of this, the...
A Feasibility Study of Municipal Solid Waste Leachate Utilisation in Concrete
Author(s) Negar Esmaeili Nima Heidarzadeh Abstract Water was replaced with raw municipal solid waste leachate in a concrete mix. Compared with the control specimen (prepared with freshwater), the hardened concrete specimen made with 100% leachate and cured in...
Durability and Acoustic Performance of Rubberized Concrete Containing POFA as Cement Replacement
Author(s) Akram M. Mhaya, Shahiron Shahidan, Sharifah Salwa Mohd Zuki, Ghasan Fahim Huseien, Mohamad Azim Mohammad Azmi, Mohammad Ismail and Jahangir Mirza Abstract Given that rubber tires are almost immune to biological degradation, this vast amount of solid...
