ABSTRACT: This Research aim to get slump and compression strength of concrete. Coarse aggregate gradation property is continuous and uniform. A hundred twenty cylinder concrete which have diameter 15 cm and high 30 cm will get six treatment to gain this parameter.The treatment of concrete were: grain size of continuous coarse aggregate max. 10 mm, 20 mm, and 38 mm; grain size of uniform coarse aggregate max. 10 mm , 20 mm, and 38 mm. Result of research indicate that concrete with continuous gradation size max. 10 mm have strength compression highest. The value is 305,02 kg/cm2, meanwhile the uniform gradation 38 mm of coarse agregat have strength compression lowest, equal to 200,71 kg/cm2, so that concluded that granulous gradation minimize and continuous gradation have strength compression highest. Result of research to slump value indicate that concrete with big size coarse agregat will have value of big slump also, as well as continuous gradation and uniform gradation

Keywords : slump value , continuous gradation, uniform gradation
