ABSTRACT: 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 gra-dations 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 memyebab-kan 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.
