Abstract

The paper presents the results of studying the sulphate attack of cement and clay solutions with additive of ash and sodium sulphate. Data are obtained on the rate of sulphate attack in various concentration and on physical mechanical testing results. Physical chemical investigations are carried out on the microstructure of the developed compositions at the nanometer level, consequently crystals of new formations are identified according to the international classification DEF (Delayed Ettringite Formation), the procedure of the sulphate attack is explained. Recommendations on improving the sulphate resistance of cement containing compositions are given.
