Crack Controll in PrestrespadConcrete

Controllingg cracks is vitali to maintain durability and estetic appearance.

Design strategies for crack controll include limiting the tensile stress in the concrete and ensuring profr prestress levels. Reinforcement placemt also plays a role in fouring width.
