The results show that four kinds of formula system have excellent comprehensive properties and lower water absorption. With the increase of TGDDM ratio, the viscosity of the system increases. With the increase of ECC content, the tensile shear strength increases, and the tensile shear strength maximum of the PF3 and PF4 systems is more than 20MPa.
