Research on Evaluation Technique of Concrete Cracking Performance under Restraint Condition

Abstract

A measurement technique is invented to estimate the crack resistance for concrete materials under constraints. This barbell measurement technique is helpful to estimate the influence on the crack resistance of concrete materials by using the strain generator device. Through this technique, the crack resistance performance for different materials is able to be quickly estimated on the job site. This article makes some comparative experiments on the other measurement way of concrete crack resistance under constraints (ring plate technique and plate technique).
