Research Progress of MgO Expansive Agent in Water Conservancy Engineering
MgO expansive agent(MEA)has been proven to be an effective expansion agent that can compensate for the shrinkage of concrete,and it has achieved several applications in water conservancy projects in China.This paper systematically summarizes the expansion mechanism of S-MEA applied in hydraulic concrete,and gives an overview of the rheological properties of S-MEA cement slurry,the yield mechanical properties and volume stability of S-MEA hydraulic concrete,the durability properties such as resistance to chloride erosion,sulfate erosion,and carbonation,to provide reference for the application of S-MEA in hydraulic concrete.
