What to Do If Cube Test Fails in Test After 28 Days?

1. It may be Concrete is firm; the cube is also firm.
2. It may be concrete is vulnerable; the cube is also vulnerable.
3. It may be Concrete is firm, but the cube is vulnerable.
4. It may be concrete is weak, but the cube is firm.

For Concrete of Grade M- 20 and Over,

Now the Inquiry of Artistry

1. Whether cubes sufficed by a trained executive?
2. Whether the strength inferior as per the right formula?
3. If so, whether they fulfill the originator with corrective styles as suggested and NDT test effects documented from labs?
4. Still doubtful go for lading test?

Concrete Cube Test Failure Reasons

1. Wrong Mix Poured The concrete blend scheduled isn't the consented combination strategy for that individual strength.
2. Wrong Mix Design There's an error in the concrete combination design. It isn't duly organized, and strength isn't duly estimated.
3. Improper Sample Collection Sometimes concrete model for the cube test isn't contained by a professed worker, or a specialized person may not correspond to it on a pinpoint. So, there may be prospects that the stockpiled concrete instance isn't truly describing the fresh Concrete delivered at the point. Indecent Cube Trial
4. The concrete cure must be a privilege per the pedagogy given in IS 516.
   • Several compressive offenses might impact the compressive strength of concrete cube during cube casting, parallel as,
   • Indecorous alignment of cube mold is acting in deformed cube shape,
   • Indecorous/ shy tamping Improper tamping results in voids conformation in the cube model
5. Shy Curing of the Cube Samples
   • The curing of the concrete cube can be as per the instruction delivered in IS 516.
   • Once the concrete cube is organized, the cubes must protect with wet gunny bags for the most undersized 24 hrs from when water is preferably counted to the Concrete.
   • Furthermore, after clearing the concrete cube from the molds and maintaining it under neat water until the test time. Completely infallible, the curing temperature is between 24 ˚C to 26 ˚C.
6. Experimenting Wrong Samples Duly, recognize the cube medication marking on the cube—periodically wrong cell sample test.
7. During Testing, this includes improper placing of molds over the CTM, pulling the face, ditching the cube, rate of cargo procedure, etc.
8. Crimes With the Testing Apparatus This may contain crimes with the reading exhibition, lading or hydraulic techniques, or a homemade blunder in homework and diagnosing the expressed value.
9. Unauthorized Water- Cement Rate Correction of the Mix Periodically, completing concrete fluently friendly labor counts repetitious water without conferring a specialized person.
10. The difference in Quality of Accoutrements Occasionally, the element of concrete accouterments utilized to possess the concrete blend on-point may discuss from those utilized while formulating the course blend.
11. Batching Factory Error There may be the possibility of batching factory error wrong accouterments volume added in the blend, due to any mechanical/ software blunder, which went unrecognized.

What to Do If We Don't Want to Strike the Concrete Member?

1 Providing Steel Casing

2. Providing Steel Stiffeners

3. Providing Fiber Reinforced Polymer (Frp) Distance Relating

4. Sprayed Concrete/ Shotcreting

5. Attaching Pre-Tensioned Lines to the Concrete Members
