STRENGTH DETERMINATION OF GYPSUM FREE PORTLAND CEMENTS CONCRETE BY NON-DESTRUCTIVE METHODS

Popis výsledku v původním jazyce

Strength tests of concrete structures from gypsum-free cement (GFC-C) could be carried out as well as on normal concrete by two ways ? on testing samples or by nondestructive methods. Paper presents practically verified calibration curves for compressivestrength calculation of BSPC-B. Calibration curves are for Schmidt hardness tester. Calibration curves published in ČSN 731373 Testing of concrete by hardness testing methods is not accurate. There was also verified rationalization of laboratory worrk by the use resonance methods for decreasing amount of tested samples, samples used for monitoring of GFC-C strength progress. Also calibration curves for diagnosis of compressive and bending strength were elaborated from dynamic compressive and tensile strength modulus, made out from resonance method of longitude oscillation self-frequency.
