"filling concrete" is a correct and usable phrase in written English.
It is typically used when describing the process of filling a hole, gap, or space with concrete material. Example: The workers spent the morning filling concrete into the cracks in the sidewalk to repair the damage caused by the harsh winter weather.
Most of previous investigations have reported that the BFS has been used as traditional construction materials (cement, roadbed filling, concrete).
These results indicate that the epoxy bonding agent was sufficient to provide the interaction between the precast U-shaped forms and the filling concrete core.
This paper proposed an innovative scheme to improve the load bearing capacity of bamboo by filling concrete or cement mortar in bamboo cavity.
Material nonlinear constitutive laws, 4-noded plane elements and frictional contact finite elements were introduced in the model at the steel concrete interface between the girder flange and the concrete slab and between the studs and the filling concrete.
When a CFST member is subjected to axial loads, the filling concrete is confined by the steel tube, resulting in a tri-axial state of compression that improves its strength, stiffness and ductility.
Numerical simulations concerned by this work lead to highlight the internal force transfer mechanisms through the specimen for several layouts and loading conditions, such as the stud arrangements, the filling concrete performance, the reinforcement percentage of the slab, the restrain slab conditions and especially the combination of axial and shear loads.
The interface performance between the steel tube and filled concrete is considered in the model.
The filled concrete increases its strength due to the confined effect and the steel plates increase the resistance against local buckling because the deformation is restricted by the filled concrete.
the main studied parameters were the stub height (200, 300, 400, 500 mm), the effect of the in filled concrete, the continued weld and the eccentric force.
Several past experimental programs have stressed that the apparent strength and stiffness enhancement phenomena observed in tensile circular steel tubes can be attributable to the filled concrete.
Therefore the tensile load was transferred from the outer steel tube to the reinforcing bars or angles through the filled concrete.
