Assessing the properties of freshly mixed concrete containing paper-mill residuals and class F fly ash
The disposal of wastewater treatment-plant solids collected from the paper-mill has become a crucial problem as the landfill space is limited. The use of paper-mill residuals in concrete formulations was investigated as an alternative to landfill disposal. Currently, there is still lack of information on the effect of fresh properties of residual concrete. Furthermore, the effect of class F fly ash on fresh...

Flexural behaviour of cantilever concrete beams reinforced with glass fiber reinforced polymers (GFRP) bars
The objective of the current study is to investigate and evaluate the flexural behavior of concrete cantilever beams when using locally produced GFRP bars as a longitudinal main reinforcement. The experimental program includes six concrete cantilever beams. The main parameters were the type of rebars (steel or GFRP), strength of concrete and ratios of GFRP rebars. The results of experiments were evaluated and...
