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.

Abstract One of the world's construction needs is casting in large volumes that require concrete with low hydration heat, and one of the problems is that the concrete has a setting during the casting queue. Therefore, a research was conducted on adding retarder to concrete with a mixture of GGBFS and Fly Ash. The purpose of this research was to analyze the physical and mechanical properties of concrete, the effect of adding retarder and obtain optimal retarder levels. This research used an experimental methods to make concrete specimens of 75% cement mix: GGBFS 15%: Fly Ash 10% with a water cement ratio of 0.5 using mix design SNI-03-2834-2000. Variations of the retarder added to the concrete mixture were 0%, 0.2%, 0.4%, and 0.6% by weight of cement with the Naptha RD 31 type. Analysis of the effect of the retarder used statistical regression test methods on SPSS. The results of research obtained the longest setting time in this researchwas 1890 minutes at a variation of 0.6% with a slump of 168 mm. The compressive strength of the concrete increased by 12.07% - 52.36% by using a retarder added material. Based on the research results, it was obtained that the optimum level of use of retarder in mixed concrete GGBFS and Fly Ash was 0.2% because it has the best physical and mechanical properties.

Abstract

Kelurahan Beji Timur memiliki wilayah topografi dataran rendah bergelombang dengan kemiringan sampai 20 %, sehingga terdapat daerah cekungan. Jika intensitas hujan cukup tinggi, daerah cekungan ini sering kebanjiran. Penyebabnya antara lain adanya kiriman air dari daerah yang lebih tinggi. Sementara tanah sebagai peresapan air banyak yang sudah tertutupi oleh beton dan aspal akibat semakin padatnya pemukiman penduduk.  Air dalam jumlah yang banyak dan deras yang tidak bisa tertampung lagi oleh drainase menggenang dan mengakibatkan banjir dan hal ini terjadi setiap tahun. Tentu saja banjir sangat merugikan bagi masyarakat yang bermukim di daerah itu. Tim Pengabdian Kepada Masyarakat (PKM) mencoba berpartisipasi menanggulangi banjir dengan membuat sumur resapan. Sumur resapan memberikan banyak keuntungan antara lain mengurangi aliran permukaan dan mencegah terjadinya genangan air, mempertahankan tinggi muka air tanah dan menambah persediaan air tanah. Sumur resapan ini menggunakan material beton non pasir yang merupakan inovasi teknologi beton ringan. Beton non pasir yang bersifat mudah dilalui air karena tidak menggunakan agregat halus (pasir) sangat cocok digunakan sebagai material untuk sumur resapan. Sumur resapan yang akan dibuat sebanyak 3 (tiga) buah dan mempunyai diameter 100 cm. Lokasi yang dipilih untuk penempatannya adalah daerah yang lebih tinggi dari daerah cekungan, dan merupakan daerah tangkapan hujan yaitu RT 04/RW 02 Kelurahan Beji Timur. Sehingga dengan dibuatnya sumur resapan diharapkan dapat mencegah terjadinya banjir dan dapat menjaga persediaan air tanah pada waktu musim kemarau
