Abstract |
|
RPC is an ultra-high strength and high ductility composite material with advanced mechanical properties. The high strength concrete fail under fatigue loads at load level below its static capacity. In the present study reactive Powder concrete with compressive strength of 165 MPa was produced. The hardened concrete is tested for compressive strength, flexural strength and flexural fatigue strength. An experimental investigation performed in which total 54 flexural fatigue tests and 15 static flexural tests are conducted on RPC specimens 100 x 100 x 500 mm in size containing steel fibre and polypropylene fibres separately. The results obtained from flexural fatigue tests are presented as S-N curve, with maximum fatigue stress expressed as a percentage of the strength under static loading and S-N relation is developed by carrying out regression analysis to determine fatigue life. |
