These concrete crushers and concrete shears demolish concrete quickly and efficiently while reducing noise and vibrations. With great dimensions and thick teeth, the rotational crusher ensures that youll get an impressive penetration in concrete structures and very low maintenance costs.
The concrete crushers updated planetary gearbox delivers accurate maneuverability and precision when positioning the machine during demolition. The rotational crusher includes an integrated hydraulic installation that permits the multi-system to make a 360 rotation in both directions for fast, accurate and efficient positioning of the jaws in any working condition. This makes it ideal for operators who use excavators with very long booms.
The concrete crusher is made of reinforced HARDOX and WELDOX steel and features a two-cylinder system for improved durability and reliability. The clutching installation permits a constant 360 rotation making it perfect for excavators without a rotation installation.
We specialize in demolition attachments amp hydraulic attachments. We can help you find the right hydraulic attachment for your needs and budget. Our attachments come with a 3 year warranty, a price match guarantee amp free shipping in the USA.

Chengqing Wu, Yu Su, in Development of Ultra-High Performance Concrete Against Blasts, 2018.
Fig. 3.55 shows the NSC slab after 8kg TNT detonation at 1.5m above the slab center, and the slab failed completely with a permanent deflection of 190mm which was manually measured after the test. Although some shear cracks can be observed, the failure of the NSC slab was predominantly flexure with a major crack in the slab mid-span. After the blast load impinged upon the slab, tensile crack was initiated on the slab distal surface. With the increase of the slab deflection, longitudinal reinforcement started yielding and the slab failed after concrete crush on the slab proximal surface.
Sep 10, 2015nbsp018332I need some advice, Mobile Jaw or Impact crusher. We recycle concretebricks etc for about 6 years, We ran Komatsu 380 Jaw crushers and it worked well I sold this unit 12months ago.Im Looking to start crushing again and a few blokes have been saying mobile impact crushers are the go in stead of the jaw,I would like to buy a machine around 30 ton mark any coments.
They crush concrete of up to 600 Mm 23.62 in thickness and cut steel reinforcements of up to 28 mm 1.10 in diameter. The crushers feature replaceable breaker tips and reinforcement cutting blades made of of high tensile steel HB 500. The crushing force is independent of the excavators hydraulic pressure by means of a hydraulic booster.

2. Strain in the steel and the surrounding concrete is the same prior to crushing of the concrete or yielding of the steel. 3. Concrete in the tension zone of the section is neglected in the flexural analysis and design calculations, and the tension reinforcement is assumed to resist the total tensile force Concrete tensile strength is.
Jan 15, 2020nbsp018332Concrete Installation When Is Reinforcement Needed What Are the Properties of Concrete Concrete contains crushed rock and sand, and these aggregates help concrete slabs resist damage caused by compression. However, concretes tensile strength is only about one-tenth of its compressive strength. In virtually all cases, breaks and cracks are
Reinforced cement concrete R.C.C is the combination of ordinary concrete with the reinforcement to increase its compressive and tensile strength to a great extent.
Concrete is a versatile material for modern construction which is prepared by mixing well-proportioned quantities of cement even lime in some cases, sand, crushed rock or gravel, and water.
As you know that, Concretehas a very high compressive strength, but it is low in tensile strength.
Thus, when only the compressive loads are acting on the concrete surface, then there is no need of using reinforcement in it.
But where tensile forces are also involved, as in, beams and slabs, there is a very high risk of its failure when plain concrete is used.
The crushing ratio of limestone, rubble, and asphalt is about 101. Which depends on the concrete grade and the reinforced concrete crushing ratio is 101 to 151. If limestone, rubble, bricks, inferior concrete in a closed process equipped with a final screen and material returning equipment, the rock crushing ratio can be up to 201 or higher.
Hence, when these two concrete and steel are combined together,.
These crushers reduce the concrete size into pieces that can be easily managed or recycled, and also split the concrete from steel reinforcement. Numerous types of jaws are used, including the shear jaws, cracking jaws, and pulverizing jaws. The jaws used are in accordance with the material characteristics, and the size required by crushing.
May 19, 2020nbsp018332Work Method Statement for Plain and Reinforced Cement Concrete PCC and RCC SCOPE The work of Plain Cement concrete shall consist of laying and compacting of cement concrete on excavated earth in accordance with the requirements of Technical Specifications accordingly to lines, grades and cross sections shown on the drawings.
Pile crushing done right. Pile crushing is an entirely different beast when compared to pile cutting. This technique is used when piles that have already been driven or poured need to be modified. The process breaks down the concrete exterior of the pile without harming the reinforcement.
Reinforced cement concrete Since concrete is a brittle material and is strong in compression. It is weak in tension, so steel is used inside concrete for strengthening and reinforcing the tensile strength of concrete. The allowable stresses are fractions of the crushing strength of concrete fc and the yield strength fy. Because of
