KAJIAN KUAT LEKAT TULANGAN BAMBU WULUNG BERTAKIKAN TIPE "V" SEJAJAR DAN TIDAK SEJAJAR DENGAN JARAK TAKIKAN 6 CM DAN 7 CM PADA BETON NORMAL

Abstract

The study of bond strength notched Wulung bamboo reinforcement type "V" with distance notched 6 cm and 7 cm in normal concrete to find valueof bond strength of bamboo reinforcement as a substitute steel reinforcement in normal concrete. The method in this study is an experimentalmethod at laboratory. Test specimen is cylinder concrete which its diameter and high was 15 cm and 30 cm. In the middle of test specimen wasburied a reinforcement with 15 cm of depth. The reinforcement in the form of steel and Wulung bamboo. Bamboo reinforcement is used there are 4variations, namely notched Wulung bamboo parallel type "V" notch at a distance of 6 cm, 7 cm and notched Wulung bamboo not aligned type"V" notch at a distance of 6 cm, 7 cm. Then compared the results with plain steel reinforcement diameter of 8 mm. From the test results, obtainedthe average bond strength of plain steel reinforcement was 0.259 MPa. The average bond strength notched Wulung bamboo reinforcement parallelwith a distance of 6 cm and 7 cm respectively are 0,01085 MPa and 0.00687 MPa. The average bond strength notched Wulung bamboo`reinforcement is not parallel to the notch distance of 6 cm and 7 cm, respectively, 0,0053 MPa and 0,0158 MPa. Comparison of the averagebond strength plain notched Wulung bamboo 1/27 to plain steel reinforcement.
