FIBER CONCRETE STUDY WITH THE ADDITION OF PALM SIGNS ON THE COMPRESSIVE STRENGTH OF CONCRETE

Concrete is part of a construction formed by mixture cement, water, fine aggregate, coarse aggregate either crushed stone or gravel and other mixed materials. Fiber concrete whose method manufacture added with fiber, both man-made fiber natural such as palm fruit bunches. The addition bunches to the mix ​​expected increase compressive strength concrete. percentage marks 6%, 8% 11% weight cement FAS 0.35. test object used was cube (15 x 15 15) cm total 12 objects for 7 days age 28 age. results 7-day average BTTS were 310.76 kg/cm2, BDTS (6%) 260.23 (8%) 237.83 kg/cm2 (11%) 244.67 kg/cm2. cm2. Testing at an obtained 342.20 294/18 269.42 279.72 From test, shows that can reduce in all variations, namely 11%.
