Strength and Durability Assessment of Prestressed Precast Self Compacting Concrete of Beams

Abstract

This study evaluates the strength and durability of prestressed, precast self-compacting concrete (SCC) beams of M45 grade. Prestressing enhances load resistance and crack control, while precasting ensures quality and accelerates construction. SCC improves workability and compaction without vibration. Identical beam specimens (200 mm × 200 mm × 700 mm) and concrete cubes were cast and cured for 28 days, then tested for compressive strength, flexural strength, durability, and water absorption. Results confirm that SCC with prestressing and precasting offers superior environmental resistance and construction efficiency, providing valuable insights for durable infrastructure development.
