The Influence of Shear Strain on the Torsion Capacity of Hybrid Beams [PDF]

open access: yesEngineering and Technology Journal, 2020
This research discusses experimentally the shear strain of the reinforcement concrete hybrid beams composed of reactive powder concrete (RPC) at the peripheral and conventional concrete (CC) at the core beams under torsional strength tests.

Enhancement of flexural behavior of hybrid flat slab by using SIFCON

open access: yesOpen Engineering, 2023
Flat slab systems are widely utilized in construction due to their versatility and efficient use of space. Nevertheless, they are susceptible to flexural failure, particularly in the tension zone. To address this issue, slurry-infiltrated fiber concrete (

Synergy assessment of hybrid reinforcements in concrete [PDF]

open access: yesComposites Part B: Engineering, 2018
The present paper is devoted to the assessment of synergy due to the combined use of metallic and synthetic fibres in concrete matrix. Such an evaluation is performed both at first cracking stage by computing fracture toughness, and at post-peak stage by determining two toughness indexes.

Developing a hybrid FRP-concrete composite beam

open access: yesScientific Reports, 2022
AbstractCurrent materials engineering trends put forward the development of efficient structural solutions. The steel replacement with fiber-reinforced polymers (FRP) exemplifies the key to the corrosion problem. However, the relatively low deformation modulus of typical FRP materials raises the deformations of the structural components.

The effect of metakaolin and hybrid polymers on the microstructure of concrete

open access: yesPeriodicals of Engineering and Natural Sciences (PEN), 2021
It has been established that metakaolin (MK) can be applied as a supplementary cementitious material and that some polymers can enhance substantial properties of concrete. Previous studies showed that, when used in combination, MK and polymers can complement each other, and enhance further the mechanical and durability properties of concrete, which ...
