A Study of Concrete Specimen Change Under Fracture
نویسنده
چکیده
Volumetric images of small mortar cylinders under load are acquired by X-ray microtomography. The images are binarized at different threshold values, and the connected components are extracted at each threshold with a 3D spaceand time-efficient program. Statistics of volume and surface area of separated concrete segments and cracks are collected and analyzed. Under increasing load, the concrete specimen can undergo size distortion. The largest segments and cracks account for 99% of the change. Some segments and cracks merge.

Cracks Analysis in Zavin Concrete Dam Using Fracture Mechanics Approach
Most of the existing concrete dams are subjected to cracking. These cracks are caused by various factors such as construction practices, curing, loads and volume change of mass concrete which reduce the efficiency, failure or instability of concrete dams. Using fracture mechanics as a new method to estimate stability and durability of concrete dams is recommended in scientific publications in w...

Fracture mechanics is a field of solid mechanics interested with the behaviour of materials under certain loads their distribution and finally the fracture criteria of given materials.This Paper evaluates size dependency of fracture parameters, fracture energy (Gf) and fracture process zone effective length (Cf) of concrete concluded as per Bazant’s size effect method. Fracture mechanics standa...
متن کاملDetermination of Tensile Strength and Crack Growth of a Typical Polymer Concrete Using Circular Disc Samples
Cracked and un-cracked Brazilian disc specimens subjected to diametral compression were used for conducting fracture toughness and tensile strength experiments on a polymer concrete (PC) material. The value of mode I fracture toughness (KIc) was determined from the center- cracked Brazilian disc and the indirect tensile strength (σt) was obtained from the un-cracked Brazilian disc specimen. The...
