Abstract

 

In the modern building structures, the most important thing is concrete. To increase the concrete compressive strength, it is required added ingredients to the concrete mixture. In an effort to increase the concrete compressive strength, experiment is carried out by adding water hyacinth fiber and coarse aggregate of Mantup in concrete mixture. The purpose of this study is to know the characteristics of coarse aggregate of Mantup and to determine the effect of natural water hyacinth fiber addition from the using of coarse aggregate of Mantup towards the concrete compressive strength. This research method employs experimental method with mix design reference of SNI 03-2834-2000. To determine the effect of adding the natural water hyacinth fiber and coarse aggregate of Mantup, the experiment is done with the variation of 0%, 4%, 6%, and 8% by weight of the cement. The test object used is cylinders Ø15 cm × 30 cm. The number of samples made as many as 12 samples, consisting of 4 variations and for each variation is made 3 samples. After doing the immersion for 7 days, it is done the testing that can be conversed to 28 days. From the test, obtained the result that the compressive strength for the 0% fiber variation produces compressive strength of 94,36kg/cm², for 4% fiber variation produces compressive strength of 40.44 kg/cm², for 6% fiber variation produces compressive strength of 48.53 kg/cm², and for the 8% fiber variation produces compressive strength of 47.18 kg/cm².
