3)Shrinkage & Creep Concrete Testing Criteria
Concrete Technology Lecture 3 Shrinkage & Creep Concrete Testing Criteria Shrinkage “Shrinkage is reduction in volume of concrete due to loss of water” Coefficient of shrinkage varies with time. Coefficient of shortening is: 0.00025 at 28 days 0.00035 at 3 months 0.0005 at 12 months Shrinkage = Shrinkage coefficient x Length Excessive shrinkage can be […]
