Abstract:
Principal material of
paving stone is sand. But sand availability would as component of maker
basis paving stone, longer on the wane or increasingly limited. Mining
of mass sand, can result area going worse level of the damage.
For the
purpose must be searched material alternative of lessen, even replaces
exploiting of sand as component of building, including also paving
stone. Therefore need to be performed a research about paving stone to
look for formulation of material mixture and alternative of usage of
material besides sand material, and at the same time to increase quality
of quality of paving. This research done with making specimen paving
with various filler material compositions for mixture, filler besides
sand also is added gravel having diameter 4,6 mm and having diameter 5,6
mm . Specimen is made is in the form of box of the size 10 cm x 20 cm x
6 cm. composition of Mixture is made in such a manner, starts from sand
filler only, gradual finite of sand is lessened by until without sand.
Test quality of paving is done with testing compressive strength and
water absorption. Result of research indicates that Gradasi mixture
filler paving stone hardly influences strength of the paving,
increasingly varies gradation of filler, increasingly good quality of
paving Addition of gravel at mixture filler paving stone, can increase
the paving compressive strength. improvement of Strength reachs 15,9%
for addition of gravel with diameter 4,6 mm and 17,79% for addition of
gravel is having diameter 5,6 mm. Addition of gravel having diameter 5,6
mm at mixture filler paving stone has strength of higher compress
compared to addition of gravel is having diameter 4,6 mm, the difference
can reach 5%. Besides also addition of gravel at mixture paving stone
which main filler of sand, also can lessen level of water absorption at
the paving.
