INFUENCE OF MINERAL ADDITIVES ON CORROSION RESISTANCE OF GROUTING MORTARS

The influence of mineral highly dispersed additives on the properties and corrosion resistance of grouting mortars was considered. Selected additives: bentonite clay, metaлaolin and silica. It was established that when all additives are injected into the oil-well cement, the strength of the last is reduced. The lowest strength was observed in specimens with addition of bentonite clay. The addition of metaacolin does not reduce the rate of water separation of tampon solutions and for its use it is necessary to add a stabilizing additive. Solutions containing additives bentonite clay and silica conform to requirements of standards for this indicator. Highest corrosion resistance in cement with silica.
