Abstract

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

Abstract

Admixture is an additional ingredient in concrete that is added when mixing concrete takes place in the hope of changing the properties of concrete to make it more suitable for a particular job. In this study, the material used was Sikacrete W with a percentage of 0%, 13% and 16% by weight of cement. The specimens used were cylinders (15 x 30) cm of 12 specimens for each FAS. FAS variations in this study included 0.35, 0.40 and 0.50 with a test age of 28 days. The results of this study, for FAS 0.35 the average concrete compressive strength for STATPLA was 280.24 kg/cm2, STATPDA was 110.38 kg/cm2, SDATPDA (13%) was 244.00 kg/cm2 and SDATPDA (16%) was 256.89 kg/cm2. FAS 0.40 average concrete compressive strength for STATPLA is 272.09 kg/cm2, STATPDA is 94.37 kg/cm2, SDATPDA (13%) was 237.18 kg/cm2 and SDATPDA (16%) was 249.18 kg/cm2. FAS 0.50 average concrete compressive strength for STATPLA was 238.83 kg/cm2, STATPDA was 74.05 kg/cm2, SDATPDA (13%) was 192.22 kg/cm2 and SDATPDA (16%) was 202.23 kg/cm2. These results indicate that there is an influence on FAS variations in concrete casting in brackish water with the addition of admixture.
