Performance Analysis of Self Compacting Concrete (SCC) with Material Add Silica Fume and Viscosity

Self Compacting Concrete (SCC) is one of the innovations in concrete to make work easier. Self Compacting Concrete (SCC) or self-compacting concrete is concrete that has high liquid properties so that it can fill space and compact itself with little or even without a vibrator. The research method is an experimental method with a mixture composition in this test, namely SCC N 0% without Silica Fume and SCC + SF 3%, SCC + SF 4%, SCC + SF 5% with Silica Fume additives and with Superplasticizer Viscocrete-3115 N 2%. Includes the characteristics of Self Compacting Concrete (SCC) with Slump Flow test, L-Shaped Box test, V-Funnel test and compressive strength test. From the results obtained, the volume weight of SCC concrete has a range between 2.267-2.341 kg/m³, the highest Slump Flow value is in SCC+SF 4% concrete with a value of 700 mm, the H2/H1 ratio from the L-Box Test ≥ 0.8 indicates the ability of concrete to flow through barriers well, and the best V-Funnel Time value is in SCC+SF 4% which is 7 seconds. The greatest compressive strength is in SCC+SF 5% concrete which is 26.80 Mpa at the age of 28 days compared to SCC N 0% concrete without Silica Fume which is 21.24 Mpa at the age of 28 days
