Final Answer:
The use of Supplementary Cementitious Materials in concrete offers a range of benefits, including enhanced strength, durability, and sustainability, as well as addressing specific challenges such as heat generation and alkali-silica reaction.
Step-by-step explanation:
In concrete construction, SCM (Supplementary Cementitious Materials) serves several purposes beyond meeting workability requirements. SCM refers to materials that are added to concrete in addition to the usual cementitious materials (like Portland cement) to enhance certain properties of the concrete mixture. Here are some purposes and benefits of using SCM in concrete:
