PENGARUH WAKTU PERENDAMAN TERHADAP UJI KUAT TEKAN PAVING BLOCK MENGGUNAKAN CAMPURAN TANAH, SEMEN DAN ABU SEKAM PADI DENGAN ALAT PEMADAT MODIFIKASI
ABSTRACT: Paving block is made
of by mixturing cement portland or other hidrolic material, water, and agregate
or without any other material. In this research paving blok will be made by
using of soil, cement, and rice husk ash. Besides, soaking of paving block is
aimed to improve compressive thepaving block that is suitable with SNI 03-0691
(1996). The samples of soil that is used came fromq ITERA, South Lampung. The
making of paving block samples consists of two stages. First, mixture A (10% of
cement, 5% of rice husk ash, 85% of silt soil) and mixture B (15% of cement,5%
of rice husk ash, 80% of silt soil) and the making of samples in the second
stage is to deter-mine the effect of immersion of compressive the paving block
in which the samples using is samples with optimum compressive result from
making samples in the firsh strage by time variant in 0 day, 7 days, 14 days,
21 days and 28 days and also by doing pre-burning and post-burning. From the experiment
result of innovation compressive this paving block includes to the quality
class D and absorption of paving block that is made of mixturing soil, cement,
and rice husk ash is not appropriate with SNI 03-0691 (1996). The adding of
rice husk ash gives a little influence in improving compressive of paving
block. The soaking that is done to paving block causing the decrease of compressive
till 45,7%. The highes compressive produced by paving block post-burning during
immersion 0 day that is 11,70 Mpa.
