“…These features make it suitable to cement concrete, resulting in an eco-friendly and economical material when the replacement of cement by GGBS lies between 40% and 45% by weight. In addition, although ultrafine GGBS can improve strength and durability, the addition of new materials to GGBS can increase these properties [55]. Furthermore, the mechanical properties in Self-Compacting Concretes (SCC), replaced by Granulated Blast Furnace Slag (GBFS) in the limestone aggregate from 0% to 60%, have been analysed [56].…”

Over the last few decades, the European steel industry has focused its efforts on the improvement of by-product recovery and quality, based not only on existing technologies, but also on the development of innovative sustainable solutions. These activities have led the steel industry to save natural resources and to reduce its environmental impact, resulting in being closer to its “zero-waste” goal. In addition, the concept of Circular Economy has been recently strongly emphasised at a European level. The opportunity is perceived of improving the environmental sustainability of the steel production by saving primary raw materials and costs related to by-products and waste landfilling. The aim of this review paper was to analyse the most recent results on the reuse and recycling of by-products of the steelmaking cycles as well as on the exploitation of by-products from other activities outside the steel production cycle, such as alternative carbon sources (e.g., biomasses and plastics). The most relevant results are identified and a global vision of the state-of-the-art is extracted, in order to provide a comprehensive overview of the main outcomes achieved by the European steel industry and of the ongoing or potential synergies with other industrial sectors.

“…Based on the research that has been done by found that occurs the increase of concrete compressive strength on concrete M40 with variations of a mixture of 40% on the concrete, so that the GGBFS useful for structural concrete and can reduce CO2 emissions and reduce pollution on the environment. The GGBFS is cementitious and has a content of compounds of similar chemical cement portland in general, so it could potentially be used as a material of the adhesive aggregates such as cement in general (Saranya, Nagarajan, & Shashikala, 2018). This research will use the GGBFS as a substitution material in cement and fibers coconut as an ingredient added to the mix of concrete against the weight of the concrete.…”

Development developments have an impact on the building materials industry sector. To reduce CO2 emissions due to soaring productivity of cement, the industry can use Ground Granulated Blast Furnace Slag (GGBFS) as a substitute for cement. This study aims to determine the effect of using GGBFS as a substitute for cement and coconut fiber as an additive on the workability, density, water absorption, compressive strength and split tensile strength of concrete at 3, 7, and 28 days. In this study using the experimental method with a total of 84 samples of cylindrical specimens with a size of 10cm x 20cm. This research was conducted with variations of GGBFS substitution of cement (0%, 35.5%, 43.5%) and coconut fiber as an additive (0.23%, 0.63%).The results of this study indicate that the optimum compressive strength test value at the age of 28 days is at GGBFS (35.5%) and coconut fiber (0.63%) reaches an average compressive strength of 32.32 Mpa. The SU1 variation (24.63 Mpa), SU2 variation (30.20 Mpa), SU3 variation (30.77 Mpa), SU5 variation (28.16 Mpa), SU6 variation (28.31 Mpa). Optimal splitting strength at the age of 28 days, namely the SU4 variation with GGBFS 35.5% and coconut fibers (0.63%) reached an average split tensile strength of 2.23 Mpa.

“…Dampak lingkungan terhadap emisi CO2 ini dapat diatasi dengan substitusi sebagian semen portland menggunakan granulated blast furnace slag (Arini et al, 2019). GGBFS merupakan GBFS yang dihaluskan, bersifat cementious, serta memiliki kandungan kimia yang mirip semen OPC, sehingga dapat digunakan sebagai bahan perekat agregat seperti semen pada umumnya (Saranya, P., Nagarajan, P., & Shashikala, A. P., 2018).…”

ABSTRAKJauhnya lokasi batching plant dengan tempat penuangan kerapkali membuat beton setting sehingga dibutuhkan bahan tambah retarder. Ground Granulated Blast Furnace Slag (GGBFS) memiliki komposisi kimia mirip semen. Oleh karena itu, dilakukan penelitian penambahan retarder pada beton dengan substitusi GGBFS sebagai pengganti sebagian semen untuk mengetahui pengaruh (dengan uji regresi SPSS), sifat fisik dan mekanik beton, serta mendapatkan kadar optimum penambahan retarder. Metode penelitian ini menggunakan metode eksperimental dengan variasi campuran 90% semen, 10% GGBFS dengan retarder 0%, 0,2%, 0,4%, dan 0,6% berat semen dengan fas 0,5 sesuai SNI 03-2834-2000. Hasil penelitian menunjukkan retarder 0,2% - 0,6% mampu meningkatkan kuat tekan sebesar 19,61 - 50,59%. Berdasarkan hasil penelitian diperoleh kadar optimum 0,2% karena memiliki sifat paling baik.Kata kunci: GGBFS, kuat tekan, retarder ABSTRACTLong distance between batching plant to the pouring area often causes the concrete undergo a setting, so that a retarder addition material is needed. Ground Granulated Blast Furnace Slag (GGBFS) which has a chemical composition similar to cement. Therefore, a research was conducted on retarder addition to concrete with GGBFS substitution as a partial cement substitute to obtain the effect (regression analysis method in SPSS), physical and mechanical properties of concrete, and to obtain the optimum level of retarder addition. This research used an experimental method with a mixture variation of 90% cement, 10% GGBFS with retarder percentage as follows; 0%, 0.2%, 0.4%, and 0.6% of cement weight with a water/cement is 0.5 according to SNI 03-2834-2000. The results of research with the addition of a retarder of 0.2% - 0.6% were able to increase the compressive strength by 19.61 - 50.59%. Based on the results, the optimum level of retarder is at a variation of 0.2% as it has the best physical and mechanical properties.Keywords: GGBFS, compressive strength, retarder
