Abstract

High Early Strength Self Compacting Concrete (HESSCC) is a new invention in the world of concrete technology that have workability, durability and high initial strength advantages, so it can be applied well in the pre-cast concrete world. In this research, superplasticizer used is Viscocrete 8045 and Silica Fume filler. The purpose of this research is to know the effect of Viscocrete 8045 and Silica Fume on the mechanical properties of concrete. The samples used are cylinders with 15 cm diameter and 30 cm height with a total of 48 samples using Silica Fume variation of 5%, 10%, and 15% and addition of Viscocrete 8045 as much as 1,5 %. From the test result, it is obtained that the value of concrete compressive strength increased due to the addition of the material. Compared with normal concrete, the initial compressive strength of concrete is increased with maximum value on the 15% Silica Fume variation of 13.362% while the final compressive strength of the concrete is increased with the maximum value on the 15% Silica Fume variation of 30.266%. The addition of the material has no impact on the value of tensile strength of concrete. However, at the absorbtion value, the addition of Silica Fume causes a decrease in the absorbtion value of concrete.
