| dc.description.abstract | Self-Compacting Concrete (SCC) is concrete that can flow and fill the
firmwork under its own weight. Self-compacting concrete cannot flow
without the addition of chemical admixture known as superplasticizer. In
this research, Viscocrete 3115N superplasticizer was used at 0,9% of the
cement weight to enhance workability. Mineral additives such as rice
husk ash at 10% of the cement weight and sika fume at levels of 0%, 3%,
5%, 8%, and 10% of the cement weight were also incorporated to
increase concrete strength. The mix design calculation of concrete is
based on SNI 03-2834-2000 with a planned compressive strength of 41,5
MPa. The testing conducted in this research aimed to determine the
influence of using rice husk ash and sika fume in self-compacting concrete
on the compressive strength, tensile strength, and flexural strength of 28-
day-old concrete. Additionally, self-compacting concrete were tested
using slump flow T50, V-Funnel, and L-Box tests. The research results
indicate that using a rice husk ash and sika fume can enhance the
compressive strength, tensile strength, and flexural strength of selfcompacting concrete. The compressive strength of the concrete can
increase up to 19,63%, tensile strength up to 17,65%, and flexural
strength up to 9,04% compared to normal concrete. The optimum
compressive strength was obtained in the ASP10% - SF5% variation,
reaching 44,136 MPa. However, the ASP10% - SF8% and ASP10% -
SF10% variations cannot be considered as self-compacting concrete
because it does not meet the testing requirements for concrete
characteristics according to EFNARC 2005 | en_US |
