@civilengineeringhub001: 3 joints in concrete construction you should know. Contraction joints create planned locations where cracking caused by shrinkage or contraction can occur in a controlled manner. Expansion joints accommodate movement between parts of a structure, including movement caused by temperature changes. Construction joints are planned interfaces where one concrete placement ends and another continues later. They may all be called “joints,” but their purposes and detailing are different. #civilengineeringhub001 #concretejoints #concreteconstruction #structuralengineering #civilengineering
