Perkembangan dunia teknik sipil mengalami kemajuan yang sangat pesat di era society 5.0 dan gencarnya pembangunan infrastruktur di tanah air. Beton SCC merupakan beton yang inovatif yang tidak memerlukan getaran ataupun alat pemadat karna baton SCC dapat memadat sendiri. Banyaknya kebutuhan akan material menyebabkan terjadinya penambangan ilegal yang akan merusak lingkungan. Oleh karena itu, perlu adanya alternatif lain untuk mengurangi eksploitasi alam yang semakin lama akan berdampak buruk bagi lingkungan. Tujuan dari penelitian ini yaitu pemanfaatan serbuk cangkang telur dan serbuk granit digunakan sebagai subtitusi agregat halus, limbah beton digunakan sebagai subtitusi agregat kasar. Material serbuk cangkang telur berasal dari limbah cangkang telur yang telah dihaluskan dan memiliki kandungan kalsium karbonat (CaCO3) tinggi. Dalam proses produksi granit, 30% dari setiap lempengan berubah menjadi lumpur batu. Limbah tersebut sering dimuat ke dalam truk untuk dibawa pergi dan dibuang ke alam. Limbah beton adalah material sisa beton yang sudah tidak terpakai lagi untuk konstruksi.. Hasil pengujian yang dilakukan menunjukan hasil optimum masing-masing inovasi adalah 40% serbuk cangkang telur, 20% serbuk granit dan 20% limbah beton. Okamura dan Ouichi menyatakan bahwa dalam pembuatan beton SCC, agregat halus harus lebih tinggi daripada agregat kasar. Inovasi beton SCC ramah lingkungan menggunakan serbuk cangkang telur, serbuk granit, dan limbah beton mampu menghasilkan kuat tekan >41,4 MPa dan dapat menghemat biaya Rp. 407.739 /m3 dari harga beton SCC tanpa menggunakan inovasi atau setara dengan 25,92 % lebih ekonomis.

Cement has been widely utilized as a primary material in the construction of structural and architectural elements. The cement factory industry can contribute to 30% of global carbon dioxide emissions. Geopolymers were first introduced by Davidovits in 1979 to represent inorganic polymers produced from geochemistry. Geopolymer materials make use of waste materials such as fly ash as a substitute for concrete binders. In this study, Class C (high calcium) fly ash from the Paiton Power Plant was used. The mix design for geopolymer mortar in this study employed the absolute volume calculation method. Absolute volume calculations are based on the absolute volume proportions of each constituent material within 1 m3. The compressive strength of geopolymer mortar with the addition of 5% borax to the molarity value, the alkali/cementitious ratio showed good performance in the mechanical properties of geopolymer mortar. Alkali/cementitious ratios of 0.3, 0.35, and 0.4 in Class C-based geopolymer mortar with 5% borax addition exhibited good workability, making it suitable for use as a base material in architectural material production.
