Concrete mixing obtained from the fine aggregate and coarse aggregate is sand, stone broken by adding sufficient adhesive cement and water as supporting material for purposes of chemical reactions during the process of concrete hardening and treatment progress, and may also be additional material that could serve to strengthen or accelerate the development of concrete strength. Therefore, in order to obtain concrete with a light weight, one of which is to replace the coarse aggregate is commonly used with natural stone aggregate is an alternative that has a lighter weight but has the major attributes that do not differ greatly. The method used in this study by testing it against a strong press, elastic modulus, split tensile strength, density, porosity. Increased modulus of elasticity of the variation in aggregate gradation gradations I to III of variation 14.03%. On a good variety of aggregate inter-aggregate contact area will be smaller so that the number of pores (porosity) of concrete produced would be smaller. With a small contact area porosity and the amount of cement needed in a similar treatment will be less. The more small porosity variations in the use of aggregate gradation will memyebabkan concrete gravity value greater. Small porosity values which will make the concrete more dense so that the stronger the resulting press will be great. In the strong increase in press and concrete, will be followed by a rise in value of split tensile strength and modulus of elasticity of concrete.
