Blended Cement: Types, Applications & Advantages

Blended cement is a homogeneous blend of normal Portland cement (OPC) with additives including silica fumes, fly ash, limestone, and slag to enhance the quality of the cement Blended cement are produced by intergrinding Portland cement clinker together at temperatures of about 1400–1500°C) with supplementary cementitious Blended Cement Advantages, Types and Applications Constro

What is Blended Cement? Advantages of Using Blended Cement

Blended cement has two major types: 1) Binary Blended Cement and 2) Ternary Blended Cement The first type contains OPC and one , while the other contains OPC and CementCement

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
