PENGARUH PENAMBAHAN SERAT GALVALUM PADA BETON RINGAN DENGAN TEKNOLOGI FOAM TERHADAP KUAT LENTUR, TOUGHNESS, DAN STIFFNESS

Abstract

surrounding environment. Lightweight concrete foam is made of concrete without coarse aggregate in the mix with added foam material agent (liquid
foam). The purpose of this study was to determine how much influence the addition of fiber galvalum the flexural strength, toughness, and stiffness
of lightweight concrete foam galvalum fiber. The method used in this study is an experimental method that is then theoretically analyzed. Value of
flexural strength on fiber 0 %, 0.25 % , 0.5, and 1 % , respectively, 104.28 t/m2 ; 110.31 t/m2 ; 182.99 t/m2 , and 134.98 t/m2 , at 0.5
fibers % an increase in flexural strength of 75.48 % . Toughness values occurred in 0.5 % with the addition of fiber 1407 Nmm value unchanged
at 121.92 % . Galvalum stiffness with the fiber content of 0% , 0.25 % , 0.5 % , 1 % were tested at 28 days is 5001.65 N / mm ; 7277.67
N / mm ; 8472.88 N / mm and 7957.14 N / mm. The addition of the fiber content of 0.5 % yield Stiffness value of 69.40 % compared to
the lightweight foam concrete without fibers.
