Considering the replacement ratio, reinforcement ratio, baked brick aggregate content, SF, superplasticizer content and multiphase fiber composites content, the 13 RAC beams were tested to study the 5 kinds of effects on the bearing capacity and deformation performance. Based on the experimental results, the following conclusions are drawn: the formulas for the bending bearing capacity and shear strength of recycled concrete beams were recommended, and compared with the experiment results, the reliability of the formulas was verified.

The exploitation of FRP tendon necessitates not only to improve the performances of the FRP tendon and anchoring device but also to examine its structural performances by applying it to various structures like concrete structures. This study applies CFRP tendon on internally and externally post-tensioned concrete specimens so as to observe their flexural performance considering the number of tendons and jacking force as test variables. The tests show that the externally post-tensioned specimens undergo lesser cracks with wider distribution of the cracks than the internally post-tensioned specimens with similar jacking force. In addition, the externally post-tensioned specimens with larger number of saddles experience smaller number of cracks with larger distribution. The specimens without saddle and the internally post-tensioned specimens with the same jacking force exhibit similar behavior until the yielding of the reinforcement to show different behaviors from the time at which the eccentricities of the tendons start to vary after yielding. The externally post-tensioned specimens with saddle provide increased crack load compared to the specimens without saddle, with an increase of approximately 25% of the ultimate load.

The self-compacted concrete (SCC) is a special type of concrete which settles down in the formwork and fills its every corner without any use of compaction or vibration. As SCC has higher flow-ability that causes brittle behaviour resulting in poor performance under tension and bending. The inclusion of randomly distributed short and discrete fibers is one of the most effective way to improve the tensile as well as flexural performance of SCC. In this regard this experimental study is undertaken to investigate the effect of nylon fibers (NF) on fresh and hardened properties of SCC. Two different lengths; 20 mm and 12 mm and five different volumetric percentages; 0.1, 0.2, 0.3, 0.4 and 0.5% of NF were used. The results revealed that addition of NF slightly affects the fresh properties of SCC. However, the extent of the effect is not of that order to be considered as major factor. The fresh properties for entire mixes lie within the required range according to EFNARC guidelines. The strength properties increases with addition of NF, the extent of increment is greater for the longer length of NF. The optimum volumetric fraction of NF for producing high strength SCC was found as 0.5%. Doi: 10.28991/cej-2021-03091734 Full Text: PDF
