Investigation of Stress-Strain Behavior of Plastic Concrete Using Monotonic Triaxial Compression Tests

In this paper, the mechanical behavior of plastic concrete being used in the cut-off walls of earth dams has been studied. To do the task, triaxial compression tests on the specimens in various ages and mix designs under different confining pressures have been done and the stress-strain behavior of such materials and their strength parameter changes has been experimentally investigated. It has ...

Strain-rate dependent stiffness of articular cartilage in unconfined compression.

The stiffness of articular cartilage is a nonlinear function of the strain amplitude and strain rate as well as the loading history, as a consequence of the flow of interstitial water and the stiffening of the collagen fibril network. This paper presents a full investigation of the interplay between the fluid kinetics and fibril stiffening of unconfined cartilage disks by analyzing over 200 cas...

the effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...

Mathematical Model for Predicting Stress-Strain Behaviour of Bacterial Concrete

Bacillus subtilus, a mineral precipitating microorganism, when introduced into concrete produces calcium carbonate crystals which seals the micro cracks and pores in the concrete. This process imparts high strength and durability to bacteria treated concrete along with enhancement in other mechanical properties. In order to study one such mechanical property, the stress-strain behavior of bacte...
