Research On Pavement Materials And Structural Design Of Brucite Fiber Concrete

It can be prepared by a new type of concrete pavement materials by brucite fiber mixedwith to cement concrete，being brucite fiber cement concrete. It is one important way toimprove the brittleness of the cement concrete pavement.In addition，brucite fiber as atoughening materials have a very good application future in concrete pavement applications.This article mainly expounds workability、mechanical properties、mixture ratio designand pavement structure design parameters of brucite fiber concrete as a pavement materials.we introduce the materials needed to various physical and chemical properties of brucitefiber cement, focuses on the physical and chemical properties of brucite fiber.In the second chapter of the test section, We design test programs of brucite fiberconcrete，and detailed study every application parameters impact in pavement concreteworkability and mechanical properties at brucite fiber pavement concrete application. For theworking performance through the process test and performance testing，we study the systemof the cement grade, the relationship between the amount of cement, water-cement ratio,amount of fiber, sand ratio and concrete fluidity, cohesiveness and water retention, anddetermine the optimal parameters. We can see through mechanical properties testresults,brucite fibe rhas little effect on concrete compressive strength， but when theappropriate amount can improve the flexural strength and toughness of concrete.According to experimental studying the brucite fiber concrete pavement materials，reference ordinary cement concrete pavement materials mixture designing standard conductbrucite fiber concrete proportion designing methods.Finally, it presents brucite fibers concretedesigning parameters and the formulas at concrete pavement， Calculate the relationshipbetween the brucite fiber concrete pavement slab and concrete pavement slab，Provide areference for the brucite fiber concrete pavement design.
