【Abstract】 Energy consumption situation is serious and energy saving is seldom taken into account in construction. Thermal preservation performance of cement with different fiber is studied in this paper. Results show that the adding of fiber could improve the heat preservation behavior of cement. The thermal performance of fiber/cement composite is more stable than normal cement in the environment with inconstant temperature; the primary factor that affects the heat transmission of composite is the morphological structure of fiber added. The amount of fiber added influences the heat-store performance of cement composite. Compared with the other fibers added, the adding of fiber with nine holes in fiber cross-section improves the thermal preservation behavior of cement composite most obviously.更多还原
