ABSTRACT
The use of slag as aggregate is quite reasonable because the waste slag is one that has not been
exploited well, in addition to the waste in the waste, slag also categorized tixic and hazardous waste
(B3). So, find the solution of the existing problems such as slag used as aggregate in concrete
mixes. This research was to determine the effect of variety in slag aggregate gradations on
compression strength, porosity and tensile strength of concrete side with up and down 7% from
fuller curve at 28days. From the test result obtained by the maximum compression strength of the
concrete with slag aggregate gradation that occurs at gradation III above fuller curve for 36,99
Mpa, while the maxsimum tensile strength sides also occurs in gradation III in the amount of 32,55
Mpa and for testing the minimum porosity derived porosity also occurs in gradation III is at 2,42%.
The result of testing the mechanical properties of concrete at 28 days showed that there was
influence by variety in the strength of slag aggregate concrete. That the more subtle gradations on
aggregate become the concrete more dense and has good quality.
