FRESH PROPERTIES DAN KUAT LENTUR SELF-FIBER COMPACTING CONCRETE (SFCC) DENGAN BAHAN TAMBAH ZEOLITE DAN SERAT NYLON
Abstract
Self- fiber compacting concrete (SFCC) is the development of conventional concrete with added fibre has a high liquidity can fill every cavity on mold with its own weight and can be solidified by itself without the help of a vibrator and compactor. This research aims to know the influence of nylon fiber additions and variations of the zeolite as a substitution of cement concrete testing against fresh and strong bending. This test uses the added fiber nylon with levels of 1 % and 0 %, 5 %, 10 %, and 15 % variations of zeolite as well as a superplasticizer sikament LN with levels of 1.5%. The properties of the fresh concrete was tested with testing slump-flow, T50, v-funnel, and l-box, the test results from four methods have been standard efnarc. The test of flexural strength was carried out at 7, 14, and 28 days, the test results obtained at optimum bending the strong variation of 10 % of the zeolite 4,225 MPa at 28 days of age. The addition of zeolite levels higher value cause strong bending be decreased.
