The Contrast of Concrete Brazilian and Flattened Brazilian Disc Specimen under Quasi Static Diametral Compression Tests

Abstract:

Reference the test method of the rock mechanical properties, through the concrete Brazilian and flattened Brazilian disc specimen under quasi static diametral compression tests and compared, research shows that flattened Brazilian disc specimens split eventually destroy the formation more than one cracks, on both sides along the platform has large cracks, even cracks in some specimens from the platform to the next platform throughout the ipsilateral endpoint, and complete Brazilian disc does not appear this phenomenon. Complete Brazilian disc specimens and flattened Brazilian disc test specimen loading force curves form remains the same, but flattened Brazilian disc specimens eventually reach the extreme loading force has a higher value than the first extreme loading force.
