Study on properties of untreated FGD gypsum-based high-strength …
At 28 d of standard curing, the compressive strength of the untreated FGD gypsum-based high-strength building materials was more than 42 MPa, the flexural strength reached 8 MPa, which has reached the strength requirements on P·O 42.5 Portland cement in Chinese standard GB175-2007. And its shrinkage ratio was very low, …
