Experimental Study Of The Mechanic Performances Of Hydrosoluble HP Fibre's Reinforcement To Cement Mortar And Concrete

This paper mainly deals with the effect of hydrosoluble HP fibre ,fibremesh and FDN on cement mortar's bend resistant strength and compressive strength under the same operating conditions and with different HP mixtures; Comparing fibremesh to HP, both of which have different effects on concrete's compressive strength, tensile strength and bend resistant strength ; and finally discussing HP's mechanism.The results indicate that HP can promote the toughness and strength of cement mortar and concrete, and with the increase in HP mixture, compressive strength increases more obviously than bend resistant strength does; With the hydrosoluble HP fibre added, the microstructure of mortar or concrete will change, the space web structure will be formed, which consists of mixed hydrates and HP films. As a result, the performance of mortar and concrete, with high strength and few apertures, can be improved.
