NEW INDICATOR METHOD FOR DETERMINING CARBONIZATION ZONES IN CONCRETE AND REINFORCED CONCRETE STRUCTURES

The article considers a new indicator method for identifying zones of carbonization (neutralization) concrete, which can be successfully applied in the practice inspections building structures made concrete and reinforced (at field laboratory stages work). aspects occurrence course process are considered. cases its influence on durability various objects (industrial, transport, civil, hydraulic, linear) analyzed. Carbonization lead to leaching under certain conditions. This is followed by damage armature structures. survey using A comparison effectiveness this with phenolphthalein test made. disadvantage (PPTM) that it does not allow understand full picture pH distribution over layers, because has 1 working color transition interval. difference consists higher accuracy: allows identify areas corrosion associated mass transfer target component during just beginning or fully proceeding. In addition, helps assess condition protective layer at current time. promising, assessing examined their degree damage. results study used organizing repair
