With many years of construction and application of common concrete, researchers have always been searching for a better composition. One of the notable ideas for achieving such a composition is using recycled materials. One of the materials which is suitable for environment and constant development is damaged tires .For studying mechanical properties of concrete containing tire particles, a ser...

The objectives of this study are to present a new concept of the bone anchorage using long implants in remote bone sites and to discuss four cases treated with this method. Our patients were treated with long implants with a distant anchorage in the skull bone. The planning procedure, the construction of the drill guide, and the surgical protocol are described. In the clinical cases described, ...

To achieve the efficient, rapid construction of prestressed anchor cables, in this study, through an indoor pull-out test and field basic test, we investigated mechanical behavior, expansion, drawing performance bond properties a new type high-strength, fast anchorage agent. We analyzed influence water material ratio curing time on its determined corresponding construction. It was found that an...

pervious concrete is a concrete mixture prepared from cement, aggregates, water, little or no fines, and in some cases admixtures. the hydrological property of pervious concrete is the primary reason for its reappearance in construction. much research has been conducted on plain concrete, but little attention has been paid to porous concrete, particularly to the analytical prediction modeling o...

Large deformation causing damage due to uplift force is generated in buried pipeline located in shallow trenches in marshes and saturated soils. In this paper, existing common methods of pipeline anchorage are discussed and considering advantages and disadvantages of these methods, a new method of pipeline anchorage are studied and presented. In this new developed method, geo-textile materials ...

The transfer of forces from reinforcing bars to surrounding concrete in reinforced concrete (RC) is influenced by many parameters. Several efforts were made to understand the influence of bond on global behaviour of RC members. However, the information on bond strength of high strength concrete (HSC) is lacking. An attempt was made to study the influence of various parameters on bond such as ba...

The unique self-prestressing behavior exhibited by Iron-based shape memory alloys (Fe-SMAs) coupled with the ease of application makes them suitable for numerous structural applications requiring post-installed reinforcement. However, practical realization Fe-SMA rebars as reinforcement systems entails an understanding their bond concrete to ensure use adequate anchorage length prestress transf...

Fiber materials have advantages such as light weight and high strength, corrosion resistance, fatigue easy processing production, they are widely applied in the repair renovation of concrete structures. To promote construction convenience fiber materials, raw yarn is continuously braided to form fiber-belt-bars. Based on existing research, performance bonding between fiber-belt-bars a interface...
