Question

Which of the following is not a supplementary cementitious material for cement​

Answer 1

Answer:

Supplementary cementing materials (SCMs) contribute to the properties of hardened concrete through hydraulic or pozzolanic activity. Typical examples are fly ashes, slag cement (ground, granulated blast-furnace slag), and silica fume.

Answer 2

Supplementary cementing materials contribute to the properties of hardened concrete through hydraulic or pozzolanic activity.

SCMs:

• For of sustainable construction to lead the idea tested for many  SCM.
• Long term performance of these type of cement is also a matter of my interest for Re-cycled materials except fly ash.
• The cementitious materials is based on silicate pozzolans.
• Fly ash, silica fumes and slag are composed of oxide of silicon.
• Examples for typical are fly ashes, slag cement ground, granulated blast-furnace slag and silica fume.
