In this paper, the influence of coarse aggregate on slump flow and following mechanical strengths (flexural compressive strengths), shrinkage rate, chloride penetration resistance, freeze–thaw resistance were investigated. Water–binder ratios in study 0.22, 0.30, 0.34, 0.45. Sand ratio was All samples cured for 7 d, 14 28 56 respectively. Results indicated that fluidity cement concrete with dif...

The aim of this study is to investigate the durability concrete with fly ash as a fine aggregate (CFA) in chloride salt environments. natural diffusion method used analyze strength, ion concentration, and coefficient after erosion laboratory environment. In addition, scanning electron microscopy, X-ray diffraction, Mercury intrusion porosimetry are performed clarify deterioration mechanism resu...

The massive amount of plastic waste in our natural environment is a global concern. In this study, recycling to partially replace sand concrete investigated. performance Resin8, unique combination all types plastics and Polyethylene Terephthalate (PET) concrete, has also been Replacement contents 5%, 10%, 15% for by volume were performed. mixes incorporating recycled tested against reference mi...
