Experimental investigation of concrete strength curve based on pull-out post-insert method

Investigation of Bond Stress in Pull Out Specimens with High Strength Concrete

Some international standard regulate the use of the high strength concrete, which may not be adopted generally without consideration of the differences that can exist among the materials in different countries. This paper relate the results of an experimental study consisting of pull out tests of Brazilian’s steel, with five different concrete strength 20, 40, 60, 80 and 100 MPa, and three diff...

Studies on the pull-out strength of ribbed bars in high-strength concrete

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 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...

Theoretical and Experimental Investigation into the Adhesion between Fiber-Reinforced Bitumen and Aggregates by Using Pull-out Method

Pull-Out Strength and Bond Behavior of Prestressing Strands in Prestressed Self-Consolidating Concrete

With the extensive use of self-consolidating concrete (SCC) worldwide, it is important to ensure that such concrete can secure uniform in-situ mechanical properties that are similar to those obtained with properly consolidated concrete of conventional fluidity. Ensuring proper stability of SCC is essential to enhance the uniformity of in-situ mechanical properties, including bond to embedded re...
