ABSTRACT
Magnesium phosphate cement (MPC) is a new type of cement with fast curing time, high early strength, strong adhesion, and good durability, which is used commonly to rapidly repair roads and bridges. However, MPC has high dry shrinkage, poor ductility and poor practicality. Adding fine fibers is an effective method to improve the mechanical properties and ductility of cement materials. Thus, five different fiber types with the same length (10mm) and proportion (1.2%) were added to MPC to overcome the problems mentioned above in this study. The fiber that exhibit the best mechanical properties after addition of magnesium phosphate cement and its concentration were determined by measuring the flexural and compressive strength of fiber reinforced MPC. The compressive strength and flexural strength increased by 30% and 85% respectively. These results can be used to guide the reinforcement during the construction of bridges and roads.
