Extending blending proportions of ordinary Portland cement and
This study extended blending proportion range of ordinary Portland cement (OPC) and calcium sulfoaluminate (CSA) cement blends, and investigated effects of proportions on setting time, workability, and strength development of OPCCSA blendbased mixturesThe main reasons for using slag in blended cement are: 1) improve the performances of the cement by increasing late strength and durability; 2) reduce the amount of ordinary Portland cement (PC) clinker thus reduce the CO2 emissions of the final cementitious productImpact of CSH seeding on hydration and strength of slag blended cement
