| Title of the article | Adhesion fiber-reinforced polymer bars with cement concrete |
| Abstract. | The article contains results of the tests on the pull-out of various strength concrete with samples FRP bars. Were applied FRP samples from different manufacturers having different winding parameters and covered with sand. To compare the results of the test performed as pull-out samples of steel reinforcement of class A-400, A-240 (smooth), and the smooth, coated with epoxy. All tests were performed by pulling out samples of concrete cylinders. Revealed an increase the parameters of the adhesion to concrete FRP bars by increasing its strength. Revealed the dominant role of adhesion cement concrete to the surface epoxy FRP and insignificant – spiral wound and covered with sand. Recommended type of profile, allowing more fully use the properties of FRP bars in concrete structures. Established that it is more expedient profiling rod itself FRP (similar type number 2) by its «compression» of small-tow in steps 1,2 diameter rod. It increases the specific area of contact with the concrete, improves collaboration FRP with concrete under load, enabling it to fully realize the strength properties of the FRP at work in the structure. |
