Microstructure and pore structure of concrete mixed with superfine phosphorous slag and superplasticizer
AbstractThe hydration products, microstructures and pore structures of paste with part of Portland cement replaced by superfine phosphoric slag were investigated by XRD, DTA and SEM in this article. The results shown that the appropriate replacement of Portland cement by superfine phosphoric slag can decrease the amount of portlandite, increase the amount of C–S–H gel, reduce the harmful pores (larger than 100nm), make the structure denser, and improve the microstructure and durability of concrete.
