In this article we demonstrated the study results of sulfate attack in cement-clay solutions with an additive ashes and sodium sulfate. We also made conclusions on speed of this sulfate attack. We performed physical-chemical research of the developed compositions microstructure, and as a result, we identified crystals of new formations according to the international classification DEF (Delayed Ettringite Formation), ISA (Internal Sulfate Attack), ESA (External Sulfate Attack). We explained the sulfate attack process. |
