 · concrete block with dimension of 15× 15×60 cm and core is a cylinder with 10cm diameter and 15cm height (Figure2 and 3). As shown in Table 1, two different kinds of concrete mix proportion were used in this research. Nominal maximum size of aggregates was 20 mm. Figure 1. Rebars placement in beams Figure 2. Coring of beams Figure 3. Cored beams

 · Similarly, the crushing of core concrete depends on the compressive strength of concrete and the detailing of longitudinal and transverse reinforcement. Predicting the drift corresponding to core crushing is not straightforward and different empirical expressions exist in the literature, . The buckling of longitudinal bars is a common form of ...

Concrete Crushing for Interior or Other Sensitive Projects. A small, electric demolition robot for those interior demolition applications that demand safe, fumeless equipment. A variety of concrete crushing equipment for areas …

 · The crushing of concrete cubes or cylinder samples is required in a construction especially concrete structures. The reason why this is to verify the strength given in the design mix. Let say for example for a concrete column commonly it has 60 megapascals of specified strength. When you crush it, the result should be equal or more than 60 Mpa. The specified …

 · Pile crushing is an entirely different beast than 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. This is an effective way to access the rebar when the steel cage of the pile must be tied into ...

 · Table 1.1 Example Core Tests Results. Notice that a series of coring samples are obtained as per table 1.1. According to ACI 318, as stated in ACI 214-4R-03 Chapter 7, the suspected concrete is considered adequate if …

Overview. Neoprene Pads or Pad Caps are ideal for tests between 1,500 and 7,000psi, but can also be used for concrete strengths up to 12,000psi with proper verification by the user as noted in ASTM C1231. These pads spread the compressive force evenly across specimen surfaces. Durometer hardness of neoprene pads must be matched to the design ...
