Due to increased demands for durable and high-performance concrete structures, the use of admixtures has become essential. In this paper, material properties, and durability of concrete mixed with natural inorganic minerals(R-1) are obtained from test results. Through the comparisons with OPC(Ordinary Portland Cement) concrete, the R-1 concrete shows improved compressive strength and durability.
