This paper studies the use of fly ash in concrete, cement is replaced partially by fly ash in underground construction concrete. In this experimental work concrete mix prepared with replacement of fly ash by 0%, and 20%. Effect of fly ash on compressive strength and flexural strength of underground construction concrete are studied. To study the impact of partial replacement of cement by fly ash on making concrete insert plate of SVP steel frame in undergound mines. |
