Pemanfaatan Geolical Carbon Sebagai Filler Pada Campuran Beton Dengan Fas 0.3
ABSTRACT
Research The final project which as in the title is the utilization of Geolical
Carbon used is Graphane. Graphane is the basic sheets of related carbon atoms.
The research process starts from the test of fine aggregate material and coarse
aggregate, for fine aggregate, it is tested for the modulus of thirst, specific gravity,
organic content, sludge content, volume weight and moisture content, for coarse
aggregate the thirst modulus, specific gravity, volume weight, and moisture content
are tested. water and wear test. Furthermore, the initial test was carried out which
aims to determine the level of graphane variation in concrete and produce
variations of 2.5%, 5%, 7.5% and 10% in the form of a solution to the weight of
cement. Furthermore, mixed planning is carried out using the ACI 211.1-91
method, after the concrete mix planning is completed, the slump test is carried out,
then the concrete molding process is carried out using a cube mold with a side of
15 x 15 cm, after the concrete is finished printing, the concrete is soaked (curing)
for 28 days, after 28 days the concrete is subjected to weight testing and
compression testing. The results of the compressive strength test in this study
experienced a maximum increase in variation of 7.5% with an increase in
percentage of 18.60% from normal concrete with a value of 445 kg / cm2.
