The content material of sulphoaluminate cement ranges from 0 to one hundred and the dosages of polypropylene fibers are 0 3.five , respectively. Furthermore, the mechanical properties (compressive and flexural strengths), the relative dynamic elastic modulus (RDEM) plus the chloride permeability of specimens with 50 sulphoaluminate cement and different dosages of polypropylene fibers are determined immediately after the specimens are exposed to distinctive NaCl freeze haw cycles. The water inder ratio in this study is 0.25, as well as the sand-tobinder ratio is 1.25. Results show that the Compound 48/80 site connection amongst the mechanical strengths of RPC at early curing ages (reduced than 7 d) along with the sulphoaluminate cement content material can be a linear function having a optimistic correlation. However, when the curing age reaches 14 d, the compressive and flexural strengths reduce within the type of a linear function with all the addition of sulphoaluminate cement. The correlation amongst the mechanical strengths and polypropylene fiber volume can be a positive quadratic function. Even so, the mass loss rate and flexural strength loss price enhanced within the form of a quadratic function, and RDEM shows a adverse quadratic function with all the freeze haw cycles. Additionally, the compressive strength loss rate increases linearly together with the freeze haw cycle. The addition of polypropylene fibers can proficiently boost the freeze haw resistance of cement mortar with an assembly unit of ordinary cement and sulphoaluminate cement.
