This paper discusses experimental investigations on bond stress–slip response in concrete in end anchorages of steel reinforcement. The influence of embedment length, bar diameter and lateral confinement on the end anchorage bond strength, and bond stress-slip response has been studied.

Bursting System. Bursting system can be used for concrete breaking to replace traditional handheld percussive breakers. It speeds up the demolition process and shortens the duration of noise …

This research aim to find unified relationship connect the results of these tests and correlate them with the results of crushing strength of cubes by using statistical methods in the analyzing process depending on laboratory tests carried on concrete cubes with different mixing ratios and different curing conditions, and finding correlation ...

The relationships among the crushing energy, surplus energy density, and fractal dimension of coal with different bursting liabilities were explored in detail and compared with traditional methods. This provides new research directions for quantitatively describing the energy evolution of coal.

Using hydraulic power, this breed of demolition comes in two forms – bursting and crushing. Both offer powerful, low vibration options for removing unwanted concrete and masonry. We deliver this service using the latest machinery, selected from our extensive fleet of industry tech, and a highly trained team – NVQ 2 Certified Operatives ...

Surface cracking happens while the concrete is still fresh and before it undergoes initial set. Weather conditions not favorable to concrete are the primary cause.

AusCrush and Recycle Pty Ltd is an Australian family-owned and operated company, specialising in mobile crushing and screening services.

To investigate the effectiveness of high voltage pulse discharge (HVPD) in crushing concrete slabs, HVPD in-liquid tests were conducted in pre-drilled holes in three double-layer bi-directionally reinforced and twelve single-layer bi-directionally reinforced concrete slabs.

Fenwick (1986) performed the analytical and experimental work on the post- tensioned concrete beam. Experimental and nite element study on eighteen models was presented to study bursting force developed after formation of rst crack in concrete member. Results shows that the magnitude of bursting force used for designing of anchorage zone …

Dating back to the early days of concrete structures, both the localized crushing beneath the bearing area and the bursting cracks in the concrete blocks have been observed. Bauschinger [7] may be the first to provide an approximate formula for the bearing capacity of concrete blocks.

Previous Next Concrete Drilling / Coring Core Drilling techniques are applied when precise, circular diameter cuts are needed. Sizes of holes are ranging from diameter 10mm to 1000mm. Technical Specification: Core Hole Diameter: 10mm – 1000mm Core Hole Depth: Above 10 M Core Inclined Hole: Angle ranges from +90C to –90C Stitch Coring is an…

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. What's more, the equipment can be used in ...

7 demonstration of work skills to measure, mark out, set up, connect, drill and burst 8 use and maintain hand tools, portable power tools and ancillary equipment 9 carry out bursting in reinforced concrete to given working instructions relating to vertical and/or horizontal surfaces 10 sort and remove rubble and materials 11 measure and record ...

Steel used as reinforcement of concrete elements may lead to durability issues. That is why in recent years steel bars are sometimes substituted with fibre reinforced polymer (FRP) bars. Although FRP has better durability, it lacks ductility, an important characteristic of load-bearing elements. The ductility of FRP reinforced …

course, the book also contributes to mining, especially in terms of crushing and screening, and for those seeking a greater focus on mining, 's minerals processing handbook is also available.

Crushing and Screening Handbook is a dive into the world of rock processing and aggregates production. It goes through the main factors impacting the quality and costs of aggregates, introduces different equipment, and demonstrates various processing methods. After reading the handbook, one should have a clear understanding on aggregates ...

In posttensioned concrete members, the high local stress under the anchorage causes transverse tensile stress. Therefore, it is very important to predict the bursting force to determine appropriate reinforcement details. In the present work, the existing equations of the bursting force for the anchorage zone were evaluated and an …

The reason for the formation of cracks that may cause structural damage in the concrete in fresh concrete is due to plastic shrinkage and plastic settlement; cracks also in hardened concrete are ...

If you're considering using concrete bursting on your next project, read on to learn about the top 6 benefits of concrete bursting.

See 6 ways to use concrete for construction sites in Baltimore, Northern VA, and Washington DC. These are benefits to on-site concrete crushing.

In fact, during the lining construction process, high concentrated thrust jack forces are introduced in the segments leading to both high compressive stresses under the thrust shoes that can provoke a concrete crushing and tensile transversal stresses that can cause cracks and, eventually, a splitting failure.
