Study of the properties of chemically resistant repair mortar with the use of secondary raw materials

Abstract This paper deals with the research of a new silicate-based repair mortar modified selected secondary raw materials. The aim this work is to develop chemically resistant material suitable for use in an extremely aggressive environment sewers. monitored parameters include key physical-mechanical characteristics, resistance sulphate ions and attack biogenic sulfuric acid. Chemical was tested by simulating exposure laboratory conditions, according methodology DIN 19573. obtained results show that modification reference it possible maintain values characteristics improve chemical test samples.
