PENGARUH PENAMBAHAN SERAT ECENG GONDOK PADA KUAT TEKAN PAVING BLOCK K-200
Abstract Paving block is one of the products of building materials used as the top layer of the street structure, compared to other pavements like cast concrete and asphalt, paving block has been widely chosen especially to the streets used to traversed by low-speeed vehicles. This study aims to know and analyze how strong the influence of additional water hyacinth fiber to the compressive strength of K-200 paving block. Method used in this study is experimental method, with the comparison of mix design reffering to the comparison of concrete quality mixture K-200 (SNI 7394-2008). The result is K-200 paving block decreases its compressive strength after given the mixture of water hyacinth fiber. The precentage of the lowest decrease is in the 0,2 mixture of 55,69% and the highest decrease is in the mixture of 0,8 with the decline presentage of of 82,39%. The score of compressive strength for each test object is: Normal of 209,53 kg/cm², 2% of 92,86 kg/cm², 4% of 84,53 kg/cm², 6% of 58,33 kg/cm², and 8% of 36,90 kg/cm². The relationship of non-linear regression can be seen in R² = 1 on polinomial orde 4. Paving block with with code objects test “Normal” classified as in the quality of paving block B with compressive strength of 209,53 kg/cm² (17,03 Mpa), while for paving block with extra water hyacinth fiber, it is below the compressive strength standard according to SNI 03-0691-1996.
