Permeability Study of Cracked Concrete
Cracks in concrete generally interconnect flow paths and increase concrete permeability. The increase in concrete permeability due to the progression of cracks allows more water or aggressive chemical ions to penetrate into the concrete, facilitating deterioration. The present work studies the relationship between crack characteristics and concrete permeability. In this study, feedback controll...
متن کاملGas permeability of macro-cracked concrete: effect of temperature and water saturation
This experimental work investigates the hydraulic behavior of a macro-cracked concrete, in order to improve the understanding of the coupled effects of temperature and water saturation. A concrete sample is macro-cracked using the Brazilian test technique. It is then submitted to dry or wet gas flow at different temperatures and confining pressures and its permeability is recorded. This first p...
متن کاملWater Permeability of Cracked Cementitious Composites
Cracking is one of the most severe problems facing the concrete industry worldwide. Of critical importance is the drastic decline of durability associated with these cracks, and the resulting cost of repair or replacement of concrete structures. This research examines the effect of crack width and crack frequency upon the durability of reinforced mortar, quantified by water permeability. Crack ...
متن کاملA Study of Permeability and Tortuosity of Concrete
Permeability of concrete is commonly used as a key index for assessing the durability of concrete, especially when concrete is to be exposed to the aggressive environment. For a porous material like concrete, permeability depends on porosity and pore characteristics such as pore size, orientation, connectivity, and size variation. The effects of porosity and pore characteristics on permeability...
متن کاملPermeability of Concrete Mix Design
In the present investigation, study of water permeability of concrete was carried out..The strength of concrete is depend on its mix proportions. we used high strength concrete which have its compressive strength is above 50 MPa.in order to measure co-efficient of permeability as per IS:3085-1965,the cylinder with height to diameter ratio equal to one were cast and subjected to a constant press...
