Abstract


Paving Block is the product of a cement building materials that are used as an alternative ground
cover of surface hardening. In general, paving block itself is usually made from a mixture of
coarse aggregate (gravel) and fine aggregate (sand) with a mixture of cement and water are
formed according to demand. So in this study, will provide another alternative to using a mixture
of soil and cement as well as soaking to know the effect of compressive strength.
Soil samples were taken from Kota Baru, South Lampung. The mixture used is 20% cement and
80% is soil, with a variation of immersion 7, 14, 21, and 28 days. Soaking were conducted with
and without the combustion process to be seen compressive strength and water absorption.
The result is that the compressive strength without burning has increased up to -28 immersion day
by 38.8%, while the compressive strength is experiencing burning decreased to 28 days amounted
to 20.63%.Despite an increase in the sample without fuel, and a decrease in samples that undergo
combustion, which produced the same compressive strength together to meet quality specification
D on SNI 03-0691-1996. Value of water absorption of pre-combustion meets the specification SNI
03-0691-1996 which is 3%-10%. While with combustion does not meet due to exceed 10 %.
