| Cement concrete as a building material itself is more than 100 years of history. In the future, it will be the most important materials for a very long period of time. But the main shortcoming is that the tensile strength of cement-based materials prone to cracking and brittle.Composite high performance cement-based materials is the main way, Composite materials are generally used for engineering materials will be distributed in another kind of material, in order to enhance the performance of certain purpose. The former is called a reinforced material, the latter known as the substrate.For concrete, steel reinforced material is the most important, in addition, Composite fiber-reinforced cement-based materials is the most widely used in recent years, the fastest growing of a new reinforced material. The three main roles lie in fiber strength, toughness and resistance to split.Hybrid fiber-reinforced cement-based composite materials is used two or more fibers with different properties and different scales, so that the performance of different scales and levels complement each other, to achieve the purpose of creating high-performance concrete.The current research work is not done much for light aggregate concrete, for the introduction of a single fiber or hybrid fiber lightweight aggregate concrete to enhance the mechanical properties and durability of the relevant literature also not very comprehensive. This paper mainly chooses clay ceramic this lightweight aggregate, to create a specimen with forta-ferro fiber, steel fiber, alkali-resistant glass fiber and mutual mixed each other respectively, then do the mechanical properties such as resistance and fracture test, the durability test like permeability and anti-carbonation test. Then collect the data of tests, do analysis and comparison between each other and compare the conclusion of study given by the other literatures, get the corresponding clay ceramic fiber reinforced concrete for the coarse aggregate performance of the various theories. Providing the theoretical and experimental basises to the recent studies of the fiber-reinforced lightweight aggregate concrete. |
