### Experimental study on Steel Fiber Reinforced Concrete

The partially loaded area leads to high compressive stresses underneath the loading zone, that can cause crushing failure, and tensile transverse stresses, which could provoke splitting failure. Rebars are typically adopted by designers This article relates to the investigation of the flexural behaviour of Ordinary Portland Cement (OPC) concrete slabs and High-Volume Fly ash (HVFA) concrete slabs Cracking and crushing of reinforced concrete ResearchGate

Concrete Bursting is a quiet and efficient method to weaken and remove concrete. Burster heads are inserted into pre-drilled holes and a hydraulic force applied to introduce controlled cracks in the concrete. Utilisation. Bursting. Hydraulic Bursting is one of the safest and most efficient methods of removing reinforced or mass concrete, brickwork, or natural stone. Hydraulic Bursters are placed in pre-drilled holes and expanded to induce controlled cracking of the material. Thus reducing it to manageable sections for removal.

This paper presents a mathematical model for the analysis of reinforced concrete (RC) uniaxial and biaxial columns. This proposed model is a quick and faster approach for the analysis and design of reinforced concrete rectangular columns without going through the interaction charts procedure as well as other iterative methods for the Concrete elements subjected to high compressive loads applied over a small contact area is a typical engineering problem. The partially loaded area leads to high compressive stresses underneath the loading zone, that can cause crushing failure, and tensile transverse stresses, which could provoke splitting failure.Experimental study on Steel Fiber Reinforced Concrete and Reinforced

2.2.1. Bursting region. Early research on partial area loading focused on the structural behaviour of bursting regions. The magnitude and distribution of the bursting stresses primarily depends on the applied axial compressive stresses σ x 0 = N / (b 1 d 1), the load concentration ratio m = (b 1 d 1) / (b 2 d 2) and the reinforcement layout. The The local splitting behaviour in Fibre Reinforced Concrete (FRC) elements under a high concentrated load is gaining a growing interest, especially with reference to precast tunnel segments. In fact, during the lining construction process, high concentrated thrust jack forces are introduced in the segments leading to both high Splitting and crushing failure in FRC elements subjected to a high

This involves forcing the concrete apart with a special hydraulic tool inserted into holes specially drilled for the purpose. Although the bursting process itself does not expose the operator to any vibration, in this case the holes were made with a rock drill which would have exposed the operator to vibration magnitudes as high as 15 m/s 2.The energy of the discharge pulse was approximately 95 kJ. It took 6–8 min to perform a discharge bursting experiment, and the efficiency of the pulsed-power system was approximately (0.85–0.9) m3/h. There have been relatively few studies on high voltage pulse crushing of reinforced concrete members.Experimental study on crushing of concrete slabs by high-voltage
