PENGARUH PENAMBAHAN PASIR DAN SEMEN TERHADAP KUAT TEKAN PAVING BLOCK MATERIAL TANAH MENGGUNAKAN ALAT PEMADAT MODIFIKASI
ABSTRACT: Paving blocks made
from mixture of portland cement or other hydrolysis adhesive, water, and aggregates
with or without other materials. In this study, paving blocks are made by using
a mixture of soil, portland cement and sand. In the manufacture of paving
blocks used compactor modification that are expected to increase the strength
of paving blocks that according to SNI 03-0691-1996. Soil samples tested were
from Kota Baru, South Lampung. The variation of mixture that used in this study
is by adding sand as much as 2%, 4%, 6%, 8%, and 10% and add cement as much as
3%, 6%, 9%, 12%, dan 15% as well as with the treatment of pre-combustion and
postcombustion of the sample of paving blocks. Results of testing the
compressive strength of the paving blocks with a mixture of soil , cement and sand
has meet the standard of SNI 03-0691-1996 for the classification of paving
blocks quality D which can be used for garden. The combustion process of paving
blocks is giving only slightly against the increase in paving blocks without
the process of combustion. The highest compressive strength value generated by
post-combustion of paving blocks on the variation of mixture 10 % sand + 15 %
cement + 75 % soil amounted to 10.05 MPa . While the value of the water absorption
test ranged from 16.6 % - 23.8 % so it does not meet the standard of SNI
03-0691-1996 .
