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 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...
متن کاملInfluence of Controlled Permeability Formwork on the Permeability of Concrete
Corrosion of steel reinforcement related to the intrusion of chloride ion is still the main threats to the durability of concrete structure, especially in marine environment. For the purpose of delaying the Cl− concentration at the surface of steel reinforcement reaching the critical value leading to initial corrosion, the permeability of concrete is usually improved by optimizing the concrete ...
متن کاملVirtual Pervious Concrete: Microstructure, Percolation, and Permeability
As the usage of pervious concrete continues to increase dramatically, a better understanding of the linkages between microstructure, transport properties, and durability will assist suppliers in mixture proportioning and design. This paper presents various virtual pervious concrete microstructural models and compares their percolation characteristics and computed transport properties to those o...
متن کاملPermeability testing of biomaterial membranes.
The permeability characteristics of biomaterials are critical parameters for a variety of implants. To analyse the permeability of membranes made from crosslinked ultrathin gelatin membranes and the transmigration of cells across the membranes, we combined three technical approaches: (1) a two-chamber-based permeability assay, (2) cell culturing with cytochemical analysis and (3) biochemical en...
