    • PURPOSE:To ensure accuracy and justice of test results, by entering necessary descriptions on the inside of a side wall of a main body of a test concrete frame before cramming unhardened concrete and hereafter, cramming the unhardened concrete and displaying on the outside of the test sample at a point of time of drying. CONSTITUTION:Necessary items such as a data of cramming unhardened concrete, a data of test, strength slump appointed by an ordering person, air content, a name of construction and a sign of a field supervisor as an attestor, are entered on the inside of a side wall 2 or 3 of a main body 1 of a test concrete frame and six columnar test samples cramming the ungardened concrete is made. Further, a frame is removed at a point of time of drying the unhardened concrete and dried concrete is housed in a water tank and then, aging in water is carried out. Said concrete is taken out in a week and four weeks after cramming the unhardened concrete to make a strength test and manufacture of the test sample is finished.
