Mechanical Property of Brucite Fiber Reinforced Composite Material

Abstract

In this paper, microstructure of brucite fiber was introduced briefly and its physical and chemical properties were given. Disperse method of fiber applied in concrete has been introduced. The effect of compressive strength, flexural strength of concrete and cement mortar by the addition of brucite fiber have also been discussed. The mechanism that fiber can reinforce concrete has been discussed. The results showed that the diameter of brucite fiber changes from micrometer scales to nanometer dimension with the dispersing action of water reducers. Brucite fiber can exert its high tensile strength on concrete and improve the mechanical property of cement motar and concrete. Life of bructie fiber reinforced composite material can be prolonged by the addition of brucite fiber.
