Self fiber compacting concrete (SFCC) is a development of conventional concrete with the addition of silica fume, superplasticizer, and nylon fiber. It has a high level of fluidity so that it can flow into the mold with its own weight, then able to compact itself without carrying out the compaction process with the help of vibrators and compactors. Weakness of SCC concrete which has a weakness in tensile strength, the collapse pattern has brittle properties so that it can easily collapse if there is a shock, therefore with the addition of nylon fiber to the concrete expected to be able to make the collapse pattern more ductile. This study aimed to analyze the flexural strength of SFCC at curing age 7, 14, and 28 days with the addition of silica fume variations 0%, 5%, 10%, and 15%, used 1% nylon fiber, and superplasticizer 1.5% with type of sikament LN. Fresh properties testing in this study using slump flow, T50, v-funnel and l-box. The results of testing the fresh properties concrete can be concluded that of the four methods have met EFNARC standards. The results of the highest flexural strength test were found in the variation of 5% silica fume which was 6,633 MPa at the age of 28 days. The addition of higher levels of silica fume can cause the value of flexural strength in the concrete to decrease.
