Abstract

Paving blocks are compositions of building material constructed from a mixture of Portland cement or other similar hydrolysis, water, and aggregate with or without other additives which do not reduce the quality of the material. Paving blocks in the field are made of cement, sand, aggregate, and water by mixing all the ingredients and form the paving blocks. In this research, the paving blocks are made of the mixture of soil, sand, and cement. In the process, the paving blocks are compacted by a modified penetration tool in order to improve the paving blocks quality in accordance with SNI-03-0691-1996.The soil samples used in this research were from Kota Baru, Lampung Selatan. The amount of mixture used for making the paving block was 75% of soil, 10% of sand and 15% of cement. The variations of curing time were 7 days, 14 days, 21 days and 28 days as well as with pre and post burning treatment on the paving block samples.The results of the compressive strength test to the paving blocks which are made of soil, sand, and cement showed that the cement and sand do not meet the standard of SNI 03-0691-1996 for the paving block classification because the highest compressive strength value is obtained by the paving blocks with pre and post burning treatment on the variation mixture of 75% soil, 10% sand, and 15% cement with the value 7,65 MPa and 7,25 MPa. The result of water absorption value which was between 16,6% - 25,4% do not meet the specification in SNI-03-0691-1996.Keywords: Paving block, silt, compressive strength, water absorption

Abstract

Kekuatan tanah dasar memegang peranan penting dalam mendukung suatu konstruksi seperti; jalan, bangunan gedung , jembatan dan sebagainya. Dan untuk menilai kekuatan tanah dasar tersebut, dipergunakanlan nilai CBR (California Bearing Ratio). Tetapi seringkali di lapangan, karena keterbatasan transportasi pada daerah pedalaman dan ketersediaan alat pengujian yang cukup memadai, alat yang paling mudah untuk mendapatkan nilai CBR dari tanah dasar tersebut dapat digunakan alat Dinamic Cone Penetrometer (DCP). Dari data pengujian alat DCP tadi, dengan menggunakan fungsi logaritma tertentu sesuai dengan besaran sudut konus dari alat DCP, yaitu 30o atau 60o, yang kemudian digambarkan dalam grafik hubungan antara besaran penetrasi dan jumlah tumbukan, didapatlah besaran nilai CBR. Grafik hubungan yang digunakan adalah perumusan dari Smith dan Pratt, 1983 untuk sudut konus 300 dengan persamaan Log CBR = 2,503 – 1,15 (Log DCP), dan TRL, Road Note 8, 1990, untuk sudut konus 600 dengan persamaan Log CBR = 2,48 – 1,057 (Log DCP). Sebelumnya sudah ada, grafik hubungan DCP dan CBR, akan tetapi untuk menentukan nilai CBR yang dihasilkan, harus menggunakan cara diterawang menggunakan kertas lain, dan hal ini cukup menyulitkan jika titik yang diuji sangat banyak jumlahnya. Dengan perhitungan logaritma yang diaplikasikan ke grafik dan persamaan fungsi, diharapkan dapat mempermudah dan mempersingkat waktu yang dibutuhkan untuk mengolah data DCP yang diuji. Kata kunci : Tanah dasar, grafik DCP, hubungan DCP dan CBR, logaritma DCP

Abstract

The strength of infrastructure buildings is influenced by the type of soil underneath. One type of land that is widely found in the land in the province of Lampung is fine-grained soil. The fine grained soil is meant soft clay and organic clay. Construction of the above clay will experience significant land subsidence constraints when given the loading. The load that causes the pore water pressure increases so that the pore water out and soil decreases consolidatively. Therefore, it is necessary to study soil degradation using box test and bamboo concrete mats as a means of land degradation. The result of clay decline testing using boks modeling and bamboo concrete mat, soft clay experience faster rate of process of decline (Cv) than organic clay. The magnitude of soft clay (Cc) decline is less than that of organic clay. Soft clay volumes are also changing volume (Mv) faster than organic clay. Coeficient of compression(av) of soft clay is also faster than organic clay. The total decline in total soil over a 20 year period on soft clay is smaller than that of organic clay. Keywords : Clay, Test Box, Bamboo Concrete Mattress, Soil Consolidation

Abstract

Soil sample that used as base material in this study was taken from Belimbing Sari Village area, Sub Jabung, East Lampung. Based on the testing of soil physical's characteristics, USCS classified soil samples as organic soil with medium to high plasticity and belongs to the OH group. The mixed content which used in this study was 85% soil, 10% lime, and 5% cement with curing time for 14 days, then it was divided with combustion and without combustion treatment on the paving block sample and soaked for 4, 8, 12, and 16 days. The result of this study was to obtain the average value of pressed-value on a mixture of 85% soil + 10% lime + 5% cement after the largest burning treatment and soaked for 4 days at 11.7 MPa. Thus, in addition to the combustion, the duration of immersion also affects its pressed-value. The longer it had soaked, the smaller its pressed-value would be. Therefore, this pressed-value met the requirement of the paving blocks' SNI-03-0691-1996 that was qualified on the classification of quality D which had the average pressed-value of at least 10 MPa. In addition to the pressed-value, the water absorption rate which was 15.5% -20.32% did not meet the paving blocks' requirement of SNI-03-0691-1996.Key words : Paving block, organic clay soil, compressive strength, water absorption, immersion.
