Reinforced concrete (RC), also called reinforced cement concrete (RCC), is a composite material in which concrete''s relatively low tensile strength and ductility are compensated for by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel bars and is usually embedded passively in the concrete before the concrete ...

· Crushing Load Definition. Jalal Afsar October 24, 2013 Concrete No Comments. Crushing load is the intensity of load required to crush the material. Crushing load of a material can be found out by taking out crushing stress test. Crushing load will be the load corresponding to the stress at which material get crushed.
Reinforced Concrete Engineering. DIANA''s Background in Reinforced Concrete Analysis. Failure analysis of reinforced concrete was a leading subject for research in the late 80''s and 90''s in Europe, the US and Japan. Mathematical formulations for cracking and crushing of concrete were developed and validated in experimental tests.
Development of equipment for breaking concrete pavements be they plain, mesh-and-dowel or continuously reinforced. Development of methods to remove steel that minimizes hand labor. Use and application of crushing equipment that can accommodate steel reinforcement. There are no restrictions on the types of concrete pavements that can be recycled.
A movable crushing knife (5) which is semi-circular in form and has a rear side edge (5a) which has a rectangular shape with a small curved edge section (5a1) located on the angle section, also has a front edge (5b) which is formed in general by a large curved edge section. The rear side edge is located so that it faces a side of the movable clamping jaw body (3) orientated inwards in the ...
Concrete recycling is the use of rubble from demolished concrete structures. Recycling is cheaper and more ecological than trucking rubble to a landfill. Crushed rubble can be used for road gravel, revetments, retaining walls, landscaping gravel, or raw material for new concrete.Large pieces can be used as bricks or slabs, or incorporated with new concrete into structures, a material called ...
An apparatus (10) for shearing off reinforced concrete piles and metal piles, casing and conductor pipes, and crushing reinforced concrete piles has a frame (11) with first and second ends and a cutter blade (41) movably mounted on the frame driven by hydraulic rams (21) between a retracted position adjacent to the first end and an extended position toward the second end.
· This paper reports the effect of pre-existing cracks on the web crushing strength of reinforced concrete beams. Two experimental series were conducted. The first series involved the test of four slender beams with large amounts of stirrups. The second series involved the test of five deep beams without transverse reinforcements.
Two design methods currently exist for the design of buried reinforced concrete pipe (RCP): the indirect design method and the direct design method.The direct design method employs advanced structural analysis techniques, modern concepts of reinforced concrete design, and soil characteristics in contrast to the traditional empirical nature of the indirect design approach.

Highlights This work studies the plastic hinge zone of RC flexural member with FEM modeling. Concrete crushing, rebar yielding, and curvature concentration zones are quantified. Results show that no existing models are adequate for prediction of hinge length. Chaotic phenomenon is …
· A stable growth of numerous flexural cracks is possible in moderately reinforced concrete beams, and then the load carrying capacity is connected with reaching the yield stress of reinforcing steel or concrete crushing in the compression zone. In higher reinforced concrete beams without transverse reinforcement, brittle failure can take place ...

CE 331, Fall 2010 Flexure Strength of Reinforced Concrete Beams 5 / 5 4. Calculate φ (strength reduction factor) φ is a function of the strain in the steel. If the strain in the steel (εs) is at least 2.5 times the yield strain (εy ~= 0.002 = 60 ksi / 29,000ksi = f y / Es), then the max. value of φ = 0.90 can be used.
Concrete, which must be free of trash, wood, paper and other such materials, is collected from demolition sites and put through a crushing machine, often along with asphalt, bricks and rocks. Reinforced concrete contains rebar and other metallic reinforcements, which are removed with magnets and recycled elsewhere.

Several authors of experimental studies have mentioned that delamination of concrete cover in the soffit of the slab could be observed before failure, even in cases where failures were shown to be within the shear-reinforced region or by crushing of concrete struts.
Disposing of reinforced concrete poles in recycling centers is pricey, even if it''s just the cost of transporting the material. If a company wants to be autonomous and use a stationary crusher, the rebar in the concrete can easily cut the conveyor belt or jam the machine, which results in downtime, work stops, and wasting time and money.
forced concrete beams and found that with the addition of 1% steel fibers, the ductility index can be increased by as much as . ACI 440 [5] recommends that the FRP reinforced structures should be over reinforced and concrete beams have to be designed so that they fail by concrete crushing rather than by rupture FRP reinforcement.
