This study reported the influence of CSA admixture affecting early-age strength formation of concrete. According to test results, slump of plain concrete shows that fluidity was decreased due to increase of displacement ratio. It also decreased with setting time. All specimens had successful air content and bleeding was declined due to small percentage of water to binder ratio and high percentage of CSA ratio. Setting time was promoted 3 to 6hours in 35% of W/B and 2 to 4hours in 45% of W/B. As properties of compressive strength, plain concrete was significantly dwindled, compared with that of OPC, at the early age. However, plain proportion incorporating CSA admixture much improved early-age strength reduction.
