Abstract

Terdapat dua metode produksi beton readymix yang digunakan saat ini yaitu wetmix dan drymix. Pencampuran wetmix merupakan metode pencampuran beton yang memiliki produktivitas yang lebih tinggi dibandingkan drymix. Tingginya produktivitas tipe wetmix dikarenakan pan pengaduk pada pencampuran wetmix memiliki putaran mixing yang lebih cepat dari pada tipe drymix sehingga durasi pengadukan lebih cepat. Adapun perbaikan yang dapat dilakukan untuk meningkatkan produktivitas produksi beton readymix adalah dengan merubah bentuk batching plant serta memperbesar kapasitas hooper agregat agar dapat mengurangi waktu tunggu alat lain pada operasi penggunaan loader, sebab produksi beton pada aktivitas produksi berasal dari penggunaan loader untuk transportasi agregat.

Abstract

      The work of embankment in the main dam with an upright core consists of 5 pile zones: the core, filter, random, rock, and rip-rap. There was difference in planning and implementation of embankment filling. Random and rock used quarry Bondrang in planning but blasting upstream of the excavated material was used in implementation. This difference is because there are social problems with the community surrounding the Bondrang quarry. The purpose of this thesis is to repair the dam foundation, to find out the seepage discharge, to analyze the possibility of piping, to determine the safety factor of slope stability in the dam, and to determine RAB Maindam of Bendo Dam Project Ponorogo.      The required data were of the geologic of the dam foundation, embankment materials, cross-sectional images of the dam body, and dam technical. Repairing the foundation using 3 methods : curtain grouting, consolidated grouting and blanket grouting; and for seepage calculations using the Cassagrande formula; to calculate safety figures using the Fellenius method and use the Geo-Studio 2012 application, the Seep / W program to find out the seepage discharge and the Geo-slope program to find out slope stability in maindam.      The analysis resulted in 3 methods of repairing dam:  curtain grouting with a depth of 39.83m, consolidated grouting with a depth of 5m, and blanket grouting with a depth of 15m; seepage discharge capacity <1% passing water average meaning safe; velocity seepage (7,3816 x 10-7m/sec) < velocity critical (0,004017m/sec) and 11,97  > 4 meaning safe for piping; >1.5 slope stability in various conditions without earthquake load meaning safe; 1.2 slope stability in various conditions with earthquake load meaning safe; the estimated cost IDR290,388,884,070.62 for main dam

Abstract

Self Compacting Concrete (SCC) as one type of concrete that is mostly used in building construction has good workability and can be obtained by adding filler instead of cement. Ground Granulated Blast Furnace Slag (GGBFS) has a chemical composition similar to the content in cement. Therefore, the study of the use of GGBFS was used as a partial substitute for cement in the SCC to examine the influences and quality of GGBFS on fresh concrete and to obtain SCC with the best compressive strength. This research method uses an experimental method by making SCC concrete specimens with an initial fas of 0.4 according to ACI 211.4R-93. The specimens were worked using GGBFS levels of 0%, until 80%, and using 1,4% superplasticizer, and 2% accelerator by weight of cement. The use of GGBFS at SCC can increase the value of compressive strength of about 4,27%-25,64 compared to SCC without using GGBFS. The resulted are known that GGBFS can influence compression strength. Based on the testing of fresh and hard concrete, it concluded that the best quality of SCC used 20% of GGBFS.
