COMPARISON OF GLASS FIBER REINFORCED CONCRETE & GEOPOLYMER CONCRETE WITH GLASS FIBER REINFORCEMENT

open access: yesInternational Journal of Research in Engineering and Technology, 2014
In the world most commonly used as well as durable material is concrete. In the field of concrete tech nology, glass fiber reinforced concrete (GFRC) is the recently introduc ed material. GFRC has many advantages such as light weight material, steel reinforcement corrosion free and structural deterio ration free.

Use of CFRP to provide continuity in existing reinforced concrete members subjected to extreme loads

open access: yes, 2008
textA special problem in many reinforced concrete structures built in the 1970s and earlier is the lack of continuity between elements. Continuity is a characteristic of structures essential to preventing collapse.

Shear Bearing Capacity Prediction of Steel-Fiber-Reinforced High-Strength Concrete Corbels on Modified Compression Field Theory

open access: yesBuildings
In order to analyze the shear mechanism of the steel-fiber high-strength concrete corbels, a calculation model for the shear bearing capacity of steel-fiber-reinforced high-strength concrete corbels was proposed based on the modified compression field ...
