Pengaruh Variasi silica Fumedan Perubahan Faktor Air Semen Terhadap Modulus Elastisitas Beton
Abstract: The aim of this
research is to know influence of addition silica fume and variation of water
cement ratio (w/c), also interaction of between both to elasticity modulus of
concrete. Independent variable in this research is variation of silica fume and
water cement ratio. Dependent variable is compression strength and strain for
result of elasticity modulus. The sample test of cylinder concrete with
diameter 15 cm and high 30 cm, with the variation of w/c 0,3 ; 0,35 ; 0,4 ;
0,45 ; and 0,5, and also variation of silica fume 0,5%, 10%, 15%, and 20%
cement weight. Each treatment made by 10 samples with of volume comparison of
mixer concrete 1 : 1,5 : 2,5. The result of samples test carried out 28th days
of age obtained optimum rate silica fume 9,328% with w/c 0,35 giving influence
to increase of concrete elasticity modulus of concrete to 4,191% of normal
concrete
