Hardened concrete | PPT
The document discusses various properties of hardened concrete, including strength, deformation under load, durability, permeability, and shrinkage. It explains that concrete gains strength over time through hydration. The compressive strength of concrete is influenced by factors like water-cement ratio, degree of compaction, and curing.

Blended cement exhibited high early-term strength. However, its 3d-age strength is lower than ordinary Portland cement. On the other hand, all blended cement mortars fulfil the compressive strength requirements of TS 24. Hence, it can be said that blended cement can achieve adequate early compressive strength.
