    If the cube mould of size 70.6 mm is used then the cube shall be compacted in how many layer?
    Two or three?
    If three then how many poking for each layer

      Thank you for your comment. As per ASTM C109, 50mm +- 0.25 is the standard size of the mold. If more than or less than that, you must make a standard variation.

    what were the results of the test? which curing method works best?

    • @lorenzdxb
      @lorenzdxb  2 роки тому

      Theoretically, the soaked one (wet). The hydration of the cement was on the proper curing. Since, this experiment was for students and made by students, there are lots of factors that affects the result. Thank you for your message.

      Hi, the students usually test the mortars @2 days with ave. 18.7kN=7 MPa and @7days with 45.91kN=18.36 MPa....cheers
