Sodium Sulfate Corrosion of Polypropylene Concrete Strength Curve of Impact Study

Using ultrasonic method for various corrosion instars of clear water, sodium sulfate solution corrosion respectively after block of NDT, polypropylene mortar test results calculated according to the theory of strength. Through the press again the compressive strength test, it is concluded that polypropylene mortar test block intensity of real value[4]. Through the press again the compressive strength test, it is concluded that polypropylene mortar test block intensity of real value.
