“…Rasiwan, R., Syahrani, D., Supardi, I., Rabihati, E., Abduh, M., & Haryani, S. (2022) From figure 2, we can see the relationship between variations, which shows the tensile strength and age of concrete from the picture above. The maximum tensile strength is 8.2336 MPa for variation 2 for 3 days while the minimum compressive strength is at variation 1 for 3 days of age with a compressive force of 3,118 MPa (Strzałkowski, & Garbalińska, 2020;Tjokrodimuljo, 1996;Toklu & Yazıcıoğlu, 2020;Zaharieva et al, 2004 Zaharieva et al, 2004;Zhang et al, 2018;Zhao et al, 2015;Nurkertamanda et al, 2017) 4 Conclusion…”
