Influence of Caustic Soda Flakes-Phosphogypsum on Activation and Microstructure of Carbide Slag-Flyash Ding Qingrong1, a, Ma Yuying2, Xiang Xing2 Caohong2, b,Xue Jun2 1 Yichang Highway Bureau of Hubei, Yichang Hubei China 443000; 2 School of Material Science and Engineering, Wuhan Institute of Technology, Wuhan, China 430074 a ycgljbgsxx@136.com, b caohong@mail.wit.edu.cn Keywords: caustic soda flakes; phosphogypsum; carbide slag; flyash; hydration products.
However, the caustic soda flakes -phosphogypsum can promote the formation of C-A-S-H and AFt, so can improve the strength and engineering application of the system effectively.
Therefore, many scholars apply the carbide slag-flyash in road engineering [1-4].Rostov Civil Engineering and Architecture of the former Soviet Union had mixed carbide slag, flyash, loess and phosphogypsum to take many tests, concluded that the product’s strength can in line with Class I of strength standard[5];Xu Qingfei adopts the second class carbide slag and III grade flyash, take the laboratory and field tests about concrete pavement base [6].

Finite element method is a kind of method with the aid of computer engineering analysis of discretization numerical calculation.
It has powerful computational analysis capabilities with the preprocessor and postprocessor and has been widely used in civil engineering, automotive engineering, machinery, water conservancy and hydropower engineering, mining, nuclear industry, shipbuilding and other industries and fields.

Polymer composites have been used successfully for many decades as engineering materials [2, 3].
They have been design and manufacture for various application such as aircraft, automobiles and civil structure [4, 5].
