NON-DESTRUCTIVE METHOD FOR CONTROL OF STRENGTH OF POROUS CONCRETES THROUGH PLASTIC DEFORMATION OF SURFACE

摘要

Non-destructive method for control of strength of porous concretes through plastic deformation of surface is in immersion to concrete of punch with given shape and dimensions with following determination depending on dimensions of imprints obtained of brand and class of strength. Indenter arranged in form of a ball is immersed to concrete due to static load. Separate calibration dependences make it possible to determine by results of same experiments grade and class of porous concrete by strength as well.
