PENGARUH WAKTU PEMERAMAN TERHADAP UJI KUAT TEKAN PAVING BLOCK DARI CAMPURAN TANAH, SEMEN DAN PASIR MENGGUNAKAN ALAT PENETRASI MODIFIKASI MODIFIKASI

Abstract

Abstract
Paving blocks are compositions of building material constructed from a mixture of Portland
cement or other similar hydrolysis, water, and aggregate or without other additives which do not
ruduce the quality of the material. In this research, the process of making paving blocks using a
modified penetration tool in oder to improve the paving blocks quality in accordance with SNI-03-
0691-1996. The soil samples tested from Kota Baru, Lampung Selatan. The amount of mixture
paving blocks was 75% of soil, 10% of sand and 15% of cement. The variation of curing time were
0 days. 7 days, 14 days and 28 days as well as with pre and post burning treatment on the paving
blocks samples. The result showed that the making of paving blocks using silt with additional
material of cement and sand fulfill the requirement in SNI-03-0691-1996. The addition and the
curing done could improve the physical and mechanical properties of the soil. For the
compressive strength value of the paving blocks with or without burning treatment, the best result
is shown in addition of 75% soil, 10% of sand and 15% of cement with 14 days curing time which
fulfill the requirement in SNI-03-0691-1996. The result of water absorption value which was
between 20,7% - 24,2% did not meet the specification in SNI-03-0691, 1996 that is 3% - 10%.
Keywords : paving block, silt, compressive strength, curing time, water absorption.
