“…The results of this study are also in line with research conducted by other researchers. Salain (2021) researched concrete with a high-volume fly ash mixture (ATVT). His research showed that the compressive strength, split tensile strength, and impermeability increased gradually with hydration time and reached those produced by concrete.…”

Cement, as a concrete-forming material, is a contributor to CO2 emissions in the world. Reducing cement and substituting fly ash and silica fume as concrete substitution materials in the manufacture of concrete makes green concrete without lowering the quality of the concrete. Concrete in the marine environment is frequently destroyed by severe environmental elements, such as seawater penetration; hence, high-performance concrete materials are required. This research aims to analyze the effect of adding fly ash and silica fume on concrete compressive strength and permeability. The specimens made were then immersed in freshwater and seawater. Analysis of the compressive strength test result shows that the compressive strength values for the samples treated with freshwater or seawater have exceeded the expected compressive strength of 30 MPa. The permeability test on the test object resulted in the supplementary fly ash to the concrete immersed in freshwater having a good value, i.e., the water penetration was below that required by DIN-1045, namely 5 cm. The penetration of concrete with fly ash impressed in seawater is good only in concrete with a 10% fly ash variation. The water penetration value still meets the requirements in concrete with silica fume for all variations with freshwater and seawater treatment.

“…Jika kuat tekan yang dimiliki suatu beton meningkat akibat penambahan limbah maka ikatan antara semen limbah semakin kuat sehingga kadar Zn, Cu dan Ba sulit untuk keluar. Kekuatan beton tergantung kekuatan ikat semen dengan limbah dan sifat reaktif dari permukaan limbah dalam berikatan dengan semen [16]. Menurut Keputusan Kepala Badan Pengendalian Dampak Lingkungan Nomor: KEP-03/BAPEDAL/09/1995 tentang Persyaratan Teknis Pengolahan Limbah Bahan Berbahaya dan Beracun menyebutkan bahwa kadar maksimum Zn, Cu, Ba dan fenol hasil S/S masing-masing 50 ppm, 10 ppm, 100 ppm dan 0,5-1,0 ppm [21].…”

This study aims to assess the potential use of fly ash burning coal as a substitution and materials to making concrete filler. Material used in this study were fly ash waste product from PT. SOCI MAS, phenol, Portland cement type I, sand, gravel, and water.The use of fly ash as a substitution done with the variation in the percentage of 0%, 5 %, 10 %, 20 %, and 30 % of the weight of a cement used, and the use of fly ash as a filler material was carried out adding percentage variation of, 0%, 20 %, 40 %, 60 and 65 % of the weight of a cement used.The parameters for concrete are maximum load, compressive strength, water absorption, phenol analysis test amd loose weight metal after solidification/stabilization. The best result of using fly ash as a substitution acquired at 10 % substitution that produces a maximum load of 680 kN, strong press of 32840 MPa, and the water adsorption of 1.275 %, and as a filler best results obtained on the use of the 65 filler % that produces a maximum of 825 kN and strong press of 39.494, and the water adsorption of 0,123 % MPa. The results of the analysis free phenol and metal such as Zn, Cu, Ba are 0.003 ppm, 0.010 ppm, 0.022 ppm, 0.170 ppm.
