STUDI PERBANDINGAN KUAT TEKAN BETON DENGAN AGREGAT KASAR MENGGUNAKAN METODE SNI DAN METODE MAXIMUM DENSITY

Abstract

Abstract : Variations aggregate gradation in the mixed concrete greatly affect the characteristics
of the concrete. Concrete with dense and continuous gradation is expected to reduce the levels of
air and increases the unit weight of concrete and add to the strength of concrete.Concrete mixture
was planned SNI method with 25 MPa compressive strength with cement and water factor
variation and 15 sample units. To compare the methods of concrete mixtures with the maximum
density with variation of water cement factor and sample cube 15 units.Compressive strength of
maximum density method 26 Mpa and SNI method 23,8 Mpa. The compressive strength
maksimum density method is higher 9.24 % than SNI method, it is also supported by the results of
concrete weight 8117 kg at maximum density method and 8068 kg at SNI method. Slump with
maximum density method and SNI method shows the same value, then the level of work ability
is also the same.
Keywords: Maximum Density, SNI, compressive strength of Concrete.
