I want to use MTS testing machine with maximum capacity of 300 KN, but I don't know, which size of specimens is suitable to test compression and bending strength of bio composite concrete to use MTS testing Machine (E45, 300KN) ? what is your recommendation, why, and according to which standard code? #concrete #MTS_E45
Noble Doctor, The relevant local standard must certainly establish adequate criteria. However, any equipment has its own manual and apparatus, where by inserting input data into the machine's script depending on the geometry of the mold, you can obtain the strength and / or tension - as well as desired graphics.
In fact in concrete the cube sizes were fixed to have five to six times of aggregate sizes. In you case this not the issue I suppose. However bio composite based on magnesium phosphate cement as binder have shown strength of 10 MPa. As such even if you use 100 mm cube your machine capacity is enough as this will result into 100 kN failure load for a strength of 10 MPa. (100x100x10/1000=100 kN)
I suppose I have understood your question properly.
Afshin Turk hi dear
how about cubic sample? man motoasefane be hamin ye dastgah dastresi daram chon kolan kare ma test concrete nist. baraye flexural strength test che size pishnahad midin?
