Here are 10 key facts about cement:
1.Binder: Cement is a substance that hardens to bind materials together.
2.Main type: Portland cement is the most common type, used in concrete and mortar.
3. Production: Cement production is energy-intensive and releases CO2.
4. Concrete strength: Concrete excels in compression but is weak in tension.
5.Ongoing hardening: Concrete continues to strengthen over time.
6.Widely used: Concrete is the most used man-made material globally.
7.Ancient use: Romans used concrete-like materials in construction.
8.Cement vs. concrete: Cement is the powder, concrete is the final mix.
9.Types: Various cement types exist for different applications.
10.Storage: Cement needs dry storage to avoid moisture damage.

1.Ties Used in columns, ties are provided to hold the longitudinal reinforcement bars in place and prevent them from buckling under compressive loads[

2.Stirrups Used in beams, stirrups are placed perpendicular to the longitudinal reinforcement to resist shear forces and prevent shear
