What is Temperature Crack?

Temperature Cracks is one part of a crack but I try to create a temperature crack definition

Definition

Concrete crack which developed by high or low temperature during casting of concrete is known as Temperature Cracks

• Temperature Cracks also known as “Thermal Cracks”

Concrete temperature limits are established to ensure that high-quality concrete with specified requirements is produced at various standards and specification provides limits on concrete temperature to achieve the specified strength and durability of concrete temperature limits

Code Guidelines For Thermal Crack

Changes based on the type of elements and conditions of hot or concrete temperature limit for cold weather airy or calm dry or humid conditions this article outlines concrete temperature restrictions in different conditions according to different standards such as ACI code, ASTM standards and standard Australian standard but all the code have similar condition factors set concrete temperature limit High initial temperature requires high water content to maintain required slow high water content leads to lower strength high permeability greater shrinkage lower air content at given air-entraining admixtures If ambient temperature increase in combination with high initial temperature then it reduces set time higher early age strength durability problem thermal cracking in massive concrete structure, low initial temperature lead to intolerable setting time in cool weather influence rate of strength achievement and reduce ultimate strength up to 50 per cent If fresh green concrete is frozen concrete temperature limits ACI 300 1.5, ACI 301 and ASTM C 94 said no temperature limit on fresh concrete in hot weather conditions if precautions are considered in proportioning production delivery placing and concrete curing nonetheless.
