CONCRETE CYLINDERS OF 25MPa CYLINDER COMPRESSIVE STRENGTH WITH AND WITHOUT CFRP WRAP SUBJECTED TO CYCLIC COMPRESSION

摘要

Concrete Cylinders of 25MPa and 35MPa cylinder compressive strengths subjected to monotonic loading: 1) The undamaged cylinders with 1 layer of CFRP wrap failed at a higher value of stress than the corresponding control cylinders by sudden rupture of CFRP. There was a strength increase of 40% and 28.5% for undamaged concrete cylinders with CFRP wrap of 25MPa and 35MPa cylinder compressive strengths respectively when compared to the control concrete cylinders due to good confinement provided by the CFRP.
